Unable to change jail root directory

[jstam]

I'm in the process of moving jails from one pool to another. However, I am completely unable to change the jail root directory!

I started with moving them using zfs snapshots, it looks like all the data is there and is the same.

I have two pools: "Media", and "nas4". Current jail root is /mnt/Media/jails, I'd like to change it to /mnt/nas4/jails

It seems that no matter what I do, I get the message: "Jail dataset created on a share". Even if I attempt to set the jail root directory to what it's already set to.

Really not sure how to proceed here...

EDIT: I ended up deleting all my jails, with the idea to recreate them on the new pool. But I still am unable to change the jail root directory.

Do you have a share configured on /mnt/Media or /mnt/nas4? If so, you'll need to delete the share before you can move it.

I had a share on /mnt/Media, which I've now removed, and I am able to open the jail root directory config page, make no changes, and hit save with no complaints from the interface.

I've got three samba shares on another pool /mnt/nas (note, different than nas4), but the jails aren't on that share and I'm not moving them to it.

Perhaps I'm going about the process wrong? I'm creating a new dataset "/mnt/nas4/jails", then trying to select that directory in the jail root directory config.

Sorry for the double post, and m0nkey_ thanks for your reply! I was just able to move the jail root directory!

However, I'm wondering if this is expected behavior?

Pool setup:

• /mnt/Media
• /mnt/nas
• /mnt/nas4

I was trying to move the jail root directory from /mnt/Media/jails to /mnt/nas4/jails. And was getting an error complaining that I was moving the jail root directory onto a share.

Shares set up at the time:

• /mnt/nas/experiments
• /mnt/nas/research
• /mnt/nas/storage

I wasn't able to move the jail root directory /mnt/Media/jails to /mnt/nas4/jails until I deleted all the shares on /mnt/nas.

Yes, this is expected. You cannot create a jail root on an already shared dataset.

Sorry, my pool names are kinda confusing, "nas" and "nas4". I wasn't able to move the jail root anywhere in the "nas4" pool, which has never had any shares, without deleting my shares on the "nas" pool.
