Hello, I am messing around with zfs snapshots, and was wondering if it is possible to mount a zfs snapshot. I would like to use this snapshot to backup to tape.

Ah, thanks! I thought it may be possible to show up as a separate mountpoint. But you''re right... this is not really needed!

You should probably be doing a ZFS clone and backing that up.> I am messing around with zfs snapshots, and was wondering if it is > possible to mount a zfs snapshot.

Snapshots don''t change and are perfect for backups for that reason. You don''t need to clone to be able to continue writting in the filesystem who''s snapshot you are backing up. eg: $ zfs snapshot home/darrenm/Documents at backup-`date +%F` $ tar @pf /dev/tape Documents/>> I am messing around with zfs snapshots, and was wondering if it is >> possible to mount a zfs snapshot.

Hi All,
At the time of zpool creation, user controls the zpool mount point by using
"-m" option. Is there a way to change this mount point dynamically ?
Your help is appreciated.
Thanks & Regards

Is there a way to change this mount point dynamically ?By dynamically I assume me mean after the pool has been created. If yes then do this if your pool is called "tank" and you want it mounted on /foo/bar zfs set mountpoint=/foo/bar tank Alternatively see the -R option for zpool import. -- Darren J Moffat
