Zfs mount temporary mountpoint service, even if off. This directory is created as needed, and ZFS automatically mounts the file system when the "zfs mount -a" command is invoked (without editing /etc/fstab). The correlation between ZFS properties and mount options is as follows: All my computers at home are Macs and The FreeBSD ZFS pools are mounted on /Volumes/volX on the server. There is a startup mechanism that allows FreeBSD to mount ZFS pools during system initialization. , acltype=posixacl) is sometimes necessary to ensure compatibility with ACLs and container requirements. The size of the aggregate is 0. Note. zfs set -u mountpoint=/data-old zpool/data1 zfs set -u mountpoint=/data zpool/data2 Now the properties are changed, but nothing is changed to the current mountpoints; /data still points to zpool/data1, but after a reboot, it will be zpool/data2. By default, a ZFS file system is automatically mounted when it is created. zpool import altroot= allows importing a pool with a base mount point instead of the root of It's like a temporary mountpoint for the pool. zfs [-sfnvh] [-o options] dataset mountpoint DESCRIPTION The mount. zfs create You can see where the new filesystem is created with "zfs list", "zfs get mountpoint zroot2/home" zfs set mountpoint Note the single file system, morpheus, whose mount point is the alternate root of the pool, /mnt. Users should should invoke either zfs(8) in most cases. Rerunning the mount command should show that all of the filesystems--including zroot/var, zroot/tmp, and zroot/usr--are mounted as read-write. user. It is not good, - what do you expect will happen ? But I think the proper way to address this is to add mountpoint to That should work for what you want to do, you need to have used zfs create zpool/data_storage_area to have created a storage pool under the rpool to be able to access one. This file system can then be exported and imported under an arbitrary alternate root pool on a different system by using -R alternate root value syntax. zfs mount zfs mount [-Oflv] [-o options] -a|filesystem zfs unmount [-fu] -a|filesystem|mountpoint DESCRIPTION zfs mount Displays all ZFS file systems currently mounted. With manually created snapshots the same situations. options are handled according to the Temporary Mount Point Properties section in zfsprops(7), except for those described below This property value was explicitly set for this dataset by using zfs set. zfs - mount a ZFS filesystem SYNOPSIS. The mount point for a given zpool can be moved at will with one command: # zfs set mountpoint=/foo/bar poolname Upgrading pools. Arch Wiki is wrong, zfs-mount can not be used for system datasets. /var/log dataset will then refuse to mount on a non-empty mountpoint. ZFS file systems are automatically mounted at boot time without requiring you to edit the /etc/vfstab file. Namely, systemd will get ahead of zfs-mount and populate /var/*/* with files, rendering the mountpoints non-empty. ZFS automatically mounts the newly created file system if it is created successfully. service, with additional dependencies as follows: Mounting ZFS File Systems; Managing ZFS Mount Points; Automatic Mount Points; Automatic Mount Points. Filesystems: For a filesystem called pool1/documents, the mount point is /pool1/documents. But, now I need to mount /dbbackup-prod as our codebase and Python backup script hardcoded those path. move user1's home back to /home This directory is created as needed, and ZFS automatically mounts the file system when the zfs mount -a command is invoked Po without editing /etc/fstab Pc . Mounting Filesystems. . -O compression=lz4 Use lz4 compression for the pool. The default (as mentioned above) is to mount the filesystem under the parent. Removing a mountpoint: zfs set mountpoint=none zroot/my/dataset Removing an entire dataset: zfs destroy zroot/my/dataset The difference Using Temporary Mount Properties. The following examples show how to set up and manage a ZFS file system in legacy mode: # zfs set mountpoint=legacy tank/home/eric # mount -F zfs tank/home/eschrock /mnt Now we must backup directory /home/user/ into a temporary directory such as /tmp/user-bck/ Now we give (immediate and permanent) instruction to ZFS about mount point of the pool zhome/home. Is generally recommended. The only zfs filesystem which should have a mountpoint of none is zroot/ROOT: zfs set mountpoint=none zroot/ROOT Note. Automatic mounting of / is not required because Legacy Mount Points. A file system mountpoint property of Note. You can also set the default mount point for the root dataset at creation time by using zpool create's -m option. Mount is performed immediately and will be performed on every boot. NAME mount. When upgrading ZFS to a new version, new feature might be available. zfs is part of the zfsutils package for Linux. Trying to use UFS on a ZFS filesystem doesn't make a whole lot of sense. -a Mount all available ZFS file systems. Automatic mounting of / is not required because DESCRIPTION zfs mount [-j] Displays all ZFS file systems currently mounted. When file systems are created on the NFS server, the NFS client can automatically discover these newly created file systems within their existing mount of a parent file system. g. Automatic mounting of / is not required because zfs-mount or zfs-mount-generator. Solved Remove ZFS mount points from pool. I don't want the external ZFS system to clobber or replace my current file system, nor do I want If any of the mount options described in the preceding section are set explicitly by using the -o option with the zfs mount command, the associated property value is temporarily overridden. See zfsprops(7) for more information on what properties can be set and acceptable values. The reason I'd prefer /mnt over /root is because you're most likely working on a To achieve this, you could either set mountpoint=/ and let ZFS handle things, or set mountpoint=legacy and mount it explicitly. 2 system (zroot02) that I want to temporarily mount, read only, so I can get some files off of it, then disconnect it afterward. 10 Oneric, kernel 3. files/tunes and I would like to mount it to /mnt/tunes in container The expected ZFS behavior is to refuse if the mount point is busy. I've done a fresh Debian stretch install (due to weired problems), and when the pool is imported and datasets are mounted, datasets with mountpoint=none with children datasets with mountpoint set up, the parent dataset is mounted anyway (instead of mounting just its childs), regardless the folder is non-empty and Overlay mounts are disabled. zfs mount [-vO] [-o options] -a | filesystem Mounts ZFS file systems. This approach allows for secure and controlled access to host directories from within LXC containers on Proxmox, utilizing ZFS and ACLs for efficient and flexible permissions DESCRIPTION zfs mount [-j] Displays all ZFS file systems currently mounted. Managing ZFS Mount Points. Maybe I (we) have mistaken the correct usage of jails_zfs_dataset=<foo> <jail> unless it is broken under FreeNAS. 2 using ZFS on root as the file system (zroot01). You can override the default mount point by using the How do I mount a ZFS snapshot? I created a zpool and in it there is a zfs volume. The following sudo zfs set mountpoint=/newmnt poolname/datasetname maybe the pool have to be mounted and no process using the dataset (ps aux|grep /oldmountpoint;kill -9 pidhere) Reply reply NAME mount. Final Advice. Based on the information below, I think there's something about Proxmox or Debian that hardcodes the mountpoint for / to have relatime enabled, but I'd really like a second opinion. It looks like my Ubuntu system can't do this without setting mountpoint=legacy: # zfs list -o name,canmount,mounted,mountpoint pool/test NAME CANMOUNT MOUNTED MOUNTPOINT pool/test on no /home/research/test # mount -t zfs pool/test /mnt filesystem 'pool/test' cannot Note. It should ALSO fail if $ zfs mount tank/home/bhall cannot mount 'tank/home/bhall': legacy mountpoint use mount(8) to mount this filesystem $ mount -F zfs tank/home/bhallm. Let's see if it stays after boot. share-a | filesystem Setting a different mount point. conf: zpool import -o sets temporary properties for this import only. Set the following properties for the ZFS Mountpoints in /etc/pve/storage. Automatic mounting of / is not required because # zfs get mountpoint tank/data/home NAME PROPERTY VALUE SOURCE tank/data/home mountpoint legacy local # zfs get mountpoint tank/data/home/kevdog NAME PROPERTY VALUE SOURCE tank/data/home/kevdog mountpoint legacy local I'd like to change these mounts to be handled by zfs rather than mount. ShelLuser. After that, verify all the mounted filesystems appear in df -h. Reactions: ShelLuser. To really see what's mounted just use the mount command. See zfs(8) for more information. comma-separated list of mount options to use temporarily for the duration of the mount. ; For NFS-specific options, see Mount processing parameters in z/OS Network i do have this issue - some stubborn pools go to /mnt/mnt/, and zfs set mountpoint doesn't work. I didn't realize I can change the mount point while the pool in in use. See the Temporary Mount Point Properties section of zfsprops(7) DESCRIPTION. The /mnt/mnt folder cannot be removed even after reboot. You can override the default mount point by using the zfs set command to set the mountpoint property to a specific path. # zfs set mountpoint=/mat mat/vol_4 cannot set property for 'mat/vol_4': 'mountpoint # zfs set read-only=off zroot. -l The command can also be given a path to a ZFS file system mount point on the system. DESCRIPTION mount. Mar 10, 2016 #1 I have a simple zfs pool called NAS. Automatic mounting of / is not required because Mount ZFS filesystem on a path described by its mountpoint property, if the path exists and is empty. Automatic mounting of / is not required because Encryption roots always generate zfs-load-key@root. See mount(1M) for more information. Numeric values can be specified as exact values, or in a human-readable form with a suffix of B, K, M, G, T, P, E, Z (for bytes, kilobytes, megabytes, gigabytes, I need a little help to figure out how to mount my zfs pool to a container. options are handled according to the Temporary Mount Point Properties section in zfsprops(7), except zfs mount zfs mount [-Oflv] [-o options] -a|filesystem zfs unmount [-fu] -a|filesystem|mountpoint DESCRIPTION zfs mount Displays all ZFS file systems currently mounted. zfs. As this is your root filesystem, letting ZFS manage it I've searched the net and look at zpool and zfs manpages and found nothing. zfs mount [-Oflv] [-o options] -a|-R filesystem|filesystem Mount ZFS filesystem on a path described by its mountpoint property, if the path exists and is empty.

When you change the mountpoint property from legacy or none to a specific path, In the following example, a file system is created Note. Automatic mounting of / is not required because Beginning with z/OS V2R3, a newly created VSAM linear data set is formatted during its first mount if the following conditions are true: VSAM linear data set is defined with the ZFS keyword (instead of LINEAR) or defined by using the zfsadm define command from a z/OS V2R3 or later system. Reset the mount points for the ZFS BE and its datasets. Thread starter gentoobob; Start date Mar 10, 2016; Tags remove zfs mount remove zpool mount points gentoobob. -o options An optional, comma-separated list of mount options to use temporarily for the duration of the mount. As you know when mounting a Network share in Mac it goes into /Volumes with the same share name. I sometimes forget if I mounted something or not too. However for compatibility reasons ZFS won't automatically enable new features on previously created pools. A file system can also have a mount point set in the mountpoint property. The mount option nosuid is an alias for nodevices,nosetuid. Now I have the data and want to take a snapshot so that I can view it on another machine that is not in production. tank The pool name. Then, mount all of the filesystems: # zfs mount -a. 0-15-server. Is there any way to change this path? I looked into zfs man page on FreeBSD but I am unable to find change option. It is important to set the property canmount=noauto on any file systems with mountpoint=/ (that is, on any additional boot environments you create). so i script "zfs export; zfs import; zfs mount" on every boot. One of the more important uses for temporary properties is allowing mountpoint to be set to '/' at boot time for the bootfs, while leaving it's permanent mountpoint property set to Before you begin: You need to know that the mount point must be an empty directory. This is controlled by the mountpoint property - run zfs get -rt filesystem mountpoint to see its current value for each dataset. I'm going to assume that your "source" installation is purely on ZFS, and boots directly from the ZFS pool. When I boot into single user mode, how can I mount the zfs pool to a temporary location? When I run: zpool import tank. If any of the mount options described in the preceding section are set explicitly by using the-o option with the zfs mount command, the associated property value is temporarily overridden. 0. Automatic mounting of / is not required because Note. ZFS automatically creates this mount point, if needed, and automatically mounts this file system when the zfs mount -a command is invoked, without requiring you to edit the /etc/vfstab file. You can also set i do have this issue - some stubborn pools go to /mnt/mnt/, and zfs set mountpoint doesn't work. By default, ZFS filesystems are automatically mounted in the /mypool directory. zfs helper is used by mount(8) to mount filesystem snapshots and or zfs(8) in most cases. If mountpoint is set to legacy, the filesystem should be instead mounted using mount(8). A directory can be used as a mount point for a file system. As storage you select the ZFS # zfs set mountpoint=/mnt temp-rpool/ROOT/s10_u8 # zfs mount temp-rpool/ROOT/s10_u8 ### For example, edit /a/mnt/etc/hosts # zfs set mountpoint=/ temp-rpool/ROOT/s10_u8 # zfs export temp-rpool --> But, I want to give temp-rpool its original name 'rpool' before or after this export. One of ZFS‘s many advantages is automatic mounting. Open comment sort options The mount point is stored in the pool itself so that if the pool moves between hosts it doesn't depend on managing /etc/fstab which The snapdir=visible setting makes the . In the following example, the atime property is temporarily Zfs will mount the pool automatically, unless you are using legacy mounts, mountpoint tells zfs where the pool should be mounted in your system by default. Invoked automatically as part of the boot process. ZFS does not automatically mount legacy file systems at boot time, and the ZFS mount and umount commands do not operate on datasets of this type. service, with additional dependencies as follows: Note. I'm too new to ZFS to be confident in my guesses. If ZFS is currently managing the file system but it is currently unmounted, and the mountpoint property is changed, the file system remains unmounted. It is not possible to do this prior. options are handled according to the Temporary Mount Point Properties section in zfsprops(7), except Note. Any help is appreciated. See the "Temporary Mount Point Properties" section Note. These property values are reported as temporary by the zfs get command and revert back to I'm just diving into zfs and my system will not boot. Automatic mounting of / is not required because Mounting and Unmounting Filesystems. When changing from legacy or none, ZFS automatically mounts the file system. - (none) This property is a read-only property. But, the pool name has the first letter capitalized. -f Forcefully unmount the file system, even if it is currently in use. The mount point that is stored on disk is / and the full path to /mnt is interpreted only in this initial context of the pool creation. All options are handled according to the FILESYSTEM INDEPENDENT MOUNT OPTIONS Can I mount a ZFS filesystem in two places at the same time, one of which is read-only? I suppose I could enable "unsafe, wide links" in /etc/samba/smb. The data/ds-1 is not encrypted (used as fast temporary cache) and so is automatically /tank# zfs mount tank/scans cannot Note. System Administration Guide: Oracle Solaris Zones, Oracle Solaris 10 Zones, and Resource Management is for anyone responsible for administering one or more systems that run an Oracle Solaris release. For example: # zfs inherit -r mountpoint rpool/ROOT/s10u6 # zfs set mountpoint=/ rpool/ROOT/s10u6 I created the zfs dataset and mount point to /dbbackup by typing zfs create -o mountpoint=/dbbackup zroot/mysql. You can use the NFSv4 mirror mount features to help you better manage NFS-mounted ZFS home directories. Please advice. This approach allows for secure and controlled access to host directories from within LXC containers on Proxmox, utilizing ZFS and ACLs for efficient and flexible permissions zfs inherit mountpoint zroot/tmp zfs inherit mountpoint zroot/usr zfs inherit mountpoint zroot/usr/home zfs inherit mountpoint zroot/usr/ports and so on (it may be possible to do a -R on this but I haven't checked). You can unmount ZFS file systems by using the zfs unmount subcommand. encroot=, keylocation= If the dataset is an encryption root, its mount unit will bind to zfs-load-key@root. 73T 205K /data/ds-1 # zfs mount data/ds-1 /data/ds-1 my script to load zfs keys and mount all datasets and found the issue. Before you begin: You need to know that the mount point should be an empty directory. ZFS does not automatically mount legacy file systems on boot, and the ZFS mount and umount commands do not operate on datasets of this type. If it is not, then its contents will be hidden for the duration of any subsequent mounts. Edited : Running Ubuntu Server 20. See the "Temporary Mount Point Properties" section for details. Without this property, the OS will attempt to automount all ZFS file systems and fail when multiple file systems attempt to mount at /; this will prevent your system from booting. ZFS is very flexible about mountpoints, and there are many features available to provide great flexibility. Installed ZFS from ppa also I'm using zfs-auto-snapshot. -l Load keys for encrypted filesystems as they are being mounted. I created and mounted some practice datasets, but now can't unmount them. I get: cannot mount '/tank': failed to create mountpoint: Read-only file system. -O Perform an overlay mount. atime=, relatime=, devices=, exec=, readonly=, setuid=, nbmand= Used to generate mount options equivalent to zfs mount. The mountpoint property can be inherited, so if pool/home has a mount point of /export/stuff then pool/home/user automatically inherits a mount point of /export/stuff/user ZFS Configuration: Adjusting ZFS settings (e. Since you're cloning between two different filesystem types, you'll likely want to use a tool like rsync to accomplish this. The mount- point property can be inherited, so if Volumes/pool/home has a mount point of /export/stuff, then pool/home/user automatically inherits a mount point of /export/stuff/user. I used that to backup data on another server using ISCSI. I am using FreeBSD 10. The mountpoint property is This property value was set by using the zfs mount-o option and is only valid for the lifetime of the mount. As long as Hello, I'm just getting started with ZFS (OpenZFS on Linux), and am having a noob problem. I thought I needed to export it first and then change the mount point To temporarily change a property value on a file system that is currently mounted, you must use the special remount option. zpool import altroot= allows importing a pool with a base mount point instead of the root of the file system. It should to be so easybut I can't do that. – Zimba. zfs-mount-generator is created to address this problem. These property values are reported as temporary by the zfs get command and revert back to their original values when the file system is unmounted. Commented Aug 24, Then select GUID associated with the mount point to your drive or folder path. However, if manual mounting is required, the zfs mount command can be used Unmounting ZFS File Systems. -a The command can also be given a path to a ZFS file system mount point on the system. I'd like to mount the current zfs data from a boot image. Unmounting ZFS File Systems. service. See the Temporary Mount Point Properties section of zfsprops(7) for details. When a file system is mounted, it uses a set of mount options based on the property values associated with the file system. tank will be used in throughout this guide. Perform the following steps to mount a file system. May 28, 2017 #create a mountpoint for zfs /: mkdir either boot to single-user OR kill every process that has an open file on that dataset. This property value was set by using the zfs mount-o option and is only valid for the duration of the mount. pool1), ZFS mounts it at /pool1 by default.

In particular, this make . The unmount command can take either the mount point or the file system name as an argument. When you subsequently mount a new root file system on mount point /, Refer to the following documentation for the appropriate file system-specific options: For HFS-specific options, see BPXPRMxx (z/OS UNIX System Services parameters) in z/OS MVS Initialization and Tuning Reference. I just thought iocage had its own method to mount zfs datasets inside the jail somehow. You can manage ZFS file systems with legacy tools by setting the mountpoint property to legacy. I had this out with Jordan and a few others at one point because /mnt is generally considered to be a temporary mount point under most UNIX I'm trying to mount zfs snapshot. ZFS does not automatically mount legacy file systems at boot time, and the ZFS mount and umount commands do not operate on file systems of this type. -v DESCRIPTION zfs set [-u] property=value [property=value]filesystem|volume|snapshot Only some properties can be edited. How to handle changes to a parent mount point: Since any change to a root dataset's mount point could have a knock-on effect on any nested datasets with a relative mount point there may need to be some adjustment in how the mountpoint changes are handled Use 'zfs set mountpoint=legacy' or 'zfs mount t470t/ROOT/FreeBSD-13. If mountpoint is set to legacy, the filesystem should be instead mounted using mount. ZFS automatically mounts datasets as filesystems at boot time, but filesystems can also be mounted and unmounted manually as needed. All I know right now ZFS Mounting Defaults. Automatic mounting of / is not required because I want to take a "drive" by which I mean a physical or virtual disk, and mount it to a folder, so that when I put files into that folder, they're stored on that disk. zfs directory show up during ls etc, and is probably bad, it can cause things like backup software to see all your snapshots and try to back them up. Automatic mounting of / is not required because ZFS is a volume manager and filesystem. temporary. The output of mount -q can be used for the input of unmount. conf, but I would also have to make some very unintuitive files-system access right changes (that could be reverted on the next Nextcloud snap update) that I would not be comfortable with. Allows mounting in non-empty mountpoint. The mount interface is the primary means of setting the temporary properties, but because of the use of the system mount helper and the fact that properties are not handled internal to zfs, but rather read from /proc/mounts or /etc/mtab, there are many issues with inconsistent handling, overwritten or ignored flags, and wrong paths being displayed. Using Temporary Mount Properties. so i script "zfs export; Temporary Mount Point Properties When a file system is mounted, either through mount(8) for legacy mounts or the zfs mount command for normal file systems, its mount However it might be safer to create a mountpoint first: # mkdir /mnt/temp then: # zfs mount -v -o mountpoint=/mnt/temp zroot/ROOT/default. 7T 3. I logged in as root, and then did the following: /tmp/zfs % doas ~/projects/test. If a property value is changed while the file That will make zfs mount your data pool in to a designated foo_mount point of your choice. See the "Temporary Mount Point Properties" section I've mounted my NAS drives under /mnt/NAS, but I've also put links to the mounts on my desktop and marked them as favourites in Nemo (I've been using linux for about a month now and this was pretty much the first thing I did). Automatic mounting of / is not required because # zfs list NAME USED AVAIL REFER MOUNTPOINT data 11. In the following example, a file system is unmounted by its file system name: # rpool/ROOT/pve-1 relatime on temporary. Automatic mounting of / is not required because This directory is created as needed, and ZFS automatically mounts the file system when the "zfs mount-a" command is invoked. Go to your container→Resources→Add→Mount point. # modprobe zfs Mount the file systems # zpool import -R /mnt tank # mount A normal filesystem doesn't know where it should be mounted in an hierarchy, this is only determined by /etc/fstab (or the individual mount command). The expected LINUX behavior is to allow it Should we stick to the ZFS or Linux behavior in this regard? Today we refuse to mount a dataset if the mount point is 'busy' with "stuff". Here's my situation I have a pool with a datatset called /zpool/public. If not set you can do so with. DESCRIPTION zfs set [-u] property=value [property=value]filesystem|volume|snapshot Only some properties can be edited. For descriptions of the valid MOUNT parameters for the zFS file system, see MOUNT in z/OS Distributed File Service zFS Administration. By default, file systems are mounted as /dataset, using the path provided for the file system name in the create subcommand. Legacy file systems must be managed through the mount and umount commands and the /etc/vfstab file. Its value is generated by ZFS. I run a lot of ZFS on FreeBSD, but very little on Linux. By default, a ZFS file system is automatically mounted when it is created. I'm Note. If the boot is failing because of /var mounting problems, look for a similar incorrect temporary mount point for the /var dataset. Quite handy is the -r switch for zfs get: zfs get -r mountpoint mypool Mount ZFS filesystem on a path described by its mountpoint property, if the path exists and is empty. - zfs mount Displays all ZFS file systems currently mounted. service zfs-mount. Legacy Mount Points. sudo chown -R user:user /foo_mount That will make the user user and the group user own the mount point and everything inside it, adjust the command to zfs mount [-Oflv] [-o options] -a|-R filesystem|filesystem Mount ZFS filesystem on a path described by its mountpoint property, if the path exists and is empty. I have an external hard disk with a ZFS file system from another FreeBSD 10. After that is done and since root owns the mount point you can change the owner of the mount with. For more information about temporary mount point properties, see Using Temporary Mount Properties. zfs — mount ZFS filesystem SYNOPSIS mount. For options that are specific to the temporary file system (TFS), see Mounting the TFS in z/OS UNIX System Services Planning. When you create a pool or filesystem, it‘s immediately available at a predefined path: Pools: When you create a pool (e. Perform the following steps to mount a zFS file system. It is a helper program that is usually invoked by the mount(8) or zfs(8) commands to mount a ZFS dataset. -j Displays all mounted file systems in JSON format. You'll mount the source heirarchy (your ZFS pool) at one mountpoint, and mount the destination heirarchy (one or more UFS filesystems) at a Go to Node→Disks→ZFS and click Create: ZFS to add your second disk as ZFS storage to Proxmox VE. – William Nelson. -j, --json Displays all mounted file systems in JSON format. For more information about automatically managed mount points, see Note. ZFS automatically creates the specified mount point, if needed, and automatically mounts the associated file system. Solved: the solution is to mount /mnt first, then create and mount any subdirectories under it like /mnt/root, /mnt/home, etc. After=pve-cluster. DESCRIPTION. Automatic mounting of / is not required because nullfs is what I have done in the past on FreeBSD and is a perfectly reasonable method to mount host directories in a jail.

You can determine specific mount-point behavior for a file system as described in this section. In this example, the newly created bonwick file system is mounted at /tank/home/bonwick. Automatic mounting of / is not required because ZFS Mounting Defaults. Automatic mounting of / is not required because How do I mount a ZFS snapshot? I created a zpool and in it there is a zfs volume. All options are handled according to the FILESYSTEM INDEPENDENT MOUNT OPTIONS zfs-mount or zfs-mount-generator. your best option is to boot to single-user, import the new pool to the correct place, then import the old pool with a different mountpoint (be wary of datasets in the old pool that don't just inherit the root of their mountpoint from the old pool, you'll have to remount them manually) The mount point for the root BE (rpool/ROOT/s10u6) should be /.
