Can't remove offline pool (TN Scale)

[stavros-k]

I had created a pool on SCALE with only 1 disk just to test some things, until my new disks arrive. I have unplugged the disk (the 1st pool) and connected the 4 new disks.
Created a new pool which is working fine.
Now i want remove the 1st pool, on Storage tab i can see the pool "OFFLINE" but no gear icon or anything to delete it.

On zpool status it's not listed. I can only see the boot-pool and the new 4disk pool.

Is this a bug? should it be reported on jira?

Thanks

Have you found a solution for this issue?

I also have a pool which is offline on the UI after I did an extense migration for new disks (and forgot to export the pool before disconnecting the disks). The disks are not connected to the server anymore and I have no possibility to insert them back. I still couldn't find a soluhtion to delete this pool (entry) on the UI/Config. If I select "Export/Disconnect", I get the error [ENOENT] None: PoolDataset S8TB does not exist.

Zfs commands from the commandline don't show this pool anymore.

Version: TrueNAS-SCALE-22.02-RC.2

I don't exactly remember, but I think it was a bug with a nightly that has been fixed, I reverted or upgraded to the next and fixed the issue.
But I would suggest filing a Jira ticket. So it can be fixed and won't cause this problem to other people

Thanks, I created a bug ticket: https://jira.ixsystems.com/browse/NAS-114218

I dealt with this "zombie pool" issue in CORE a long time ago... probably the same thing.

Deleting a "Zombie Pool"

I recently created myself a "Zombie Pool" by yanking out a temporary USB disk I had attached to do a backup/restore, but hadn't exported from the GUI before destroying at the CLI. This results in the GUI thinking the pool still exists, but isn't currently available, so it remains in the list...
