How do I mount a ZFS pool?
Sorry for asking an Ubuntu concerning question, but I hope that someone here has some experience with that.
I have to mount the zfs pool I created with freenas8 on Ubuntu. I tried it as described here.
I was able to run that command without error:
sudo zpool import data
and the status of my zpool is like this:
[email protected]:~$ sudo zpool status pool: data state: ONLINE status: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on older software versions. scan: none requested config: NAME STATE READ WRITE CKSUM data ONLINE 0 0 0 sda2 ONLINE 0 0 0 sdb2 ONLINE 0 0 0 errors: No known data errors
so it looks good to me. but, i dont know how to access the pool. in my eyes i have to mount it, but i dont know how.
If you run the command
sudo zfs get allit should list all the properties of you current zfs pools and file systems. One of those properties, if correctly set, should be mountpoint=.
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. If not set you can do so with
sudo zfs set mountpoint=/foo_mount data
That will make zfs mount your data pool in to a designated foo_mount point of your choice.
After that is done and since root owns the mount point you can change the owner of the mount with
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 assign correct user:group privileges to the mount point.
