Moving ZFS mount location

Impulse1 · Post by **Impulse1** » 27 May 2016 17:21

When I first set up my NAS and ZFS pool I made the mistake (I think its a mistake) of making its mount location /mnt.

As in there is no /mnt/pool/[begin NAS file structure here] its just /mnt/[begin NAS file structure here].

I realize this is a limitation if I want to add any additional pools in the future, or just separate drives. is it possible to relocate my ZFS pool to a new mount location without rebuilding the pool? I really don't want to have to go out and buy 4TB worth of external drives to backup my pool just to relocate it.

Also, is this actually something I should worry about, or would I be able to create a /mnt2 in the future if I wanted to add new drives?

No worries

Mount your pool under /mnt that's where mine has been past few years, working great

zfs set mountpoint=mnt/poolname poolname

Ok I'll just leave it as is then. I haven't had any issues so far, I was just worried about when I wanted to add an additional pool and my current pool is called /mnt.

using the set mountpoint= command, can I change the location without any risk of loosing data?

Yes, it is safe, because it won't touch the data in your pool.
You can also define the alternate mount point in GUI:

Disks|ZFS|Pools|Management|Edit

Have fun!

Can you post the output of zpool status.

In the meantime have a look at this to see if its relevant

Is this what you were looking for?

Code: Select all

 nas4free: ~# zpool status
  pool: Pool1
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
	still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
	the pool may no longer be accessible by software that does not support
	the features. See zpool-features(7) for details.
  scan: none requested
config:

	NAME        STATE     READ WRITE CKSUM
	Pool1       ONLINE       0     0     0
	  raidz2-0  ONLINE       0     0     0
	    ada0    ONLINE       0     0     0
	    ada1    ONLINE       0     0     0
	    ada2    ONLINE       0     0     0
	    ada3    ONLINE       0     0     0
	    ada4    ONLINE       0     0     0
	    ada5    ONLINE       0     0     0

errors: No known data errors

Thanks. From the GUI could you also do a Disks.zfs.configuration and report the text in the Name and Mount Point columns in the Pools(1) table.
