[HOWTO] Importing ZFS volumes from FreeNAS 8 to Nas4Free

[slaycock]

I have a ZFS volume that was created under FreeNAS 7. This has been migrated to FreeNAS and and now to NAS4Free. The pool contains a single dataset. However the pool is imported into the root directory and not under the mnt directory.

The CIFS/Samba documentation strongly suggests that shares should be located in mnt. Up to now there have been no problems, but in upgrading to the current nightly of NAS4Free I can no longer see the share. Nothing else has changed.

Any suggestions?

you need to impor from shell adding desired mount point because the mount point originally in FreeNAS 8 Do not work on FreeNAS 7 = Nas4Free.

Code: Select all

zpool import -R /mnt -f poolname

or

Code: Select all

zpool import -o mountpoint=/mnt -f poolname

PD: if your pool is actually imported, first need to export.

When done and works, go to ZFS WEBGUI and syncronize to reflect changes you do in shell.

Thanks for the prompt response. Unfortunately the two shell commands above do not work.

The command

zpool import -R /mnt -f poolname

Works for the current session but dissappears when NAS4FREE is rebooted.

The command

zpool import -o mountpoint=/mnt -f poolname

gave the response that 'mountpoint' is not a valid zpool option but your command agrees with those I've googled.

Do I need to create a directory in /mnt to be able to mount my pool.

A. Found the answer. zfs set mountpoint=/mnt/poolname poolname

Moves the pool 'poolname' also mounted as 'poolname' to a new mountpoint. Don't use just '/mnt'. Checked and it does survive a reboot.

Please also note that you will need to reimport in the GUI as synchronisation doesn't detect this change. So BEFORE you delete the pool in the GUI please export it from the command line. Then delete from the GUI. The you won't inadvertently delete the filepool as I did. If you do accidently delete the file pool then you can get it back using

zpool import -D -f poolname

However I did note that using the GUI to import a pool already imported from the command line still doesn't set the mountpoint field in the GUI ZFS configuration screen.

to see in the GUI you need to go to ZFS | Configuration | Synchronize,

And synchronize your Pool to web GUI:
