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. You can manage ZFS file systems with legacy tools by setting the mountpoint property to legacy. Although in the end we don't need ultra high end run-time performance, so I'm hoping to find that sweet spot of simplicity vs performance at least on the maintenance / troubleshooting level, if DESCRIPTION zpool import [-D] [-d dir|device] Lists pools available to import. See zpool-import(8) for details. zfs set mountpoint=/home zstorage/home It also might be that /home is a separate mount point, in that case you need to remove, comment or alter the corresponding entry in /etc/fstab. 5G 24K /conf edjstorage/storage Legacy Mount Points.

The original contents of /usr/ would be hidden from the OS. To change the mount point of the filesystem techrx/logs to /var/logs, you must first create the mount [] The mount option nosuid is an alias for nodevices,nosetuid. I enhance your answer, it can be for example like this: sudo mkdir /newmnt sudo zfs set mountpoint=/newmnt poolname/datasetname In newer versions of OpenZFS, there is the zfs set -u flag. For example, if nothing is mounted under /mnt, zpool import -R /mnt -f ztest would forcibly import pool named ztest and mount its root to /mnt. Here as you can see there is an active process using /backup partition. zfs helper is used by mount(8) to mount filesystem snapshots and mountpoint=legacy ZFS filesystems, as well as by zfs(8) when the ZFS_MOUNT_HELPER environment variable is not set. If this problem occurs, you must forcibly unmount the file system. You don't want to recursively remove the contents of the new filesystem Now you should be able to mount the ZFS filesystem on /home. txt" before the rename should still point to "/path/to/my/file. 10.

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. Promoting a clone makes the snapshot become a child of the clone, rather than of the original parent dataset. But it now has a question mark on it, saying "unable to activate storage 'pve1-data' - directory is expected to be a mount point but is not mounted: '/mnt/pve/pve1-data' (500)" When I try to reformat and mount /dev/sdb1 it says "storage ID 'pve-data' already defined (500)" But where? Another weird behavior is when I restore, it asks on which disk, I select "local-zfs". Sure, but again, the task here is to automate the process.
