4 n00b questions ... renaming zpool, getting rid of dataset, device names, add users

[danzg]

1. Now that our server is set up, I would like to rename our zpools ... I read somewhere that the way to do this is export & re-import under the new name. But will all my mount points and shares remain intact? Or will I have to set those up again?

2. I had originally set up one of our shares under a dataset ... which I now realize I don't really need; I can just share the 'root' of the volume. Can I move all the files from the dataset subfolder to the volume root, and then delete the dataset? Will my data remain intact?

3. Since adding a second SATA controller, my device names in 'zpool status' no longer correspond to the 'ada_' convention ... they look all messed up:

Is there any way to fix this so I can correlate the disks to what the GUI shows me?

4. My colleagues need to be able to add ftp users, but I'd prefer they don't have access to the full GUI ... is there any way to allow them to access only the 'Users' section?

Thanks!

Not sure if this answers question #1...

Question #3, as I understand it the naming you see is fine and should not cause any issue. The GPTID is what is used internally even if the status doesn't display it.

Oh, does FreeNAS support the 'zfs rename' command? Everywhere I searched it said you had to export/import.

I have never tried it myself and in other threads on the internet (outside FreeBSD) they talk about both export/import and using zfs rename. Since I have never tried it I cannot say it works. Whatever you do I would recommend you have a backup of your data first because shit happens even when it "should" have been a no brainer.
