is it possible to rename a zpool?

Stop the array, click on the pool, click on the pool name to change it, restart array.

This will rename an unRaid pool. I don't see a GUI way to rename a zpool yet, including using the ZFS Master plugin.

 

To answer the original question, THIS is how to do it via terminal command line. I haven't tried it, but all zfs commands I've used (thus far) have worked as expected.

After some testing, was able to rename a zpool with the following commands in terminal:

 

remove pool to be renamed:

zpool export pool_to_rename

 

re-add pool with new name

zpool import pool_to_rename new_pool_name

 

The only caveat being ZFS Master wasn't able to see pools with a period in the name. `zpool list` would still show them, but ZFS Master would not.

For anyone coming upon this post, like I did, because they wanted to rename their zpool in the webUI:

I don’t know what was the correct way or not to do this 2 years ago when TS posted the original question. But today, using 7.1.14, the method @JorgeB describes is working great for renaming a zpool in the webUI.

If you want to know what unRAID does under the hood when applying the name change in the UI you can run ”zpool history <pool_name>”.
