Okay, it looks like the Minimum free space setting was reset to 0 zero after the re-import. I'll need to fix that.

This is the Minimum free space setting under the pool settings right?

Okay, a reboot (possibly also the update I performed to 7.2.3 from 7.2.2 during the reboot) appears to have resolved the issue. Unraid now successfully mounts the pool on array start. Sincerely, I appreciate all the help you've provided in helping me resolve this issue.

Hmm, I went ahead and tried to re-add the pool like last time, only to see the import fail due to a cannot import with misplaced devices errorL Dec 30 18:08:11 Nebula emhttpd: zmain: recover volume

drives we added. I'm still able to manually import by running zpool import zmain though. Seems like the Unraid config still has the old pool data saved somewhere.

Okay, I assume you meant moving existing data from zmain to a new pool or drive. I can do that first.

I should also admit that I don't know how to move things around in a ZFS pool. Unless you meant, copying things to a new pool.

I can confirm deletes work now. Would it be quicker to run a balance operation?

Okay. I can also try deleting some files I no longer need if the delete operation works this time.

Actually, this is likely because of the 9455508329953933197 value, which should no longer be accurate since the pool is larger (also never added the 10 missing drives to the command). I can go ahead and try to reimport via the GUI.

Damn, the issue persists after adding the vdev although the error this time is slightly different: I/O error instead of an out-of-space error.

On it. I'll let you know how it goes. Same as last time, I imagine I don't need to worry about stopping the array until I'm ready to reimport, correct?

Here is the output from fdisk -l /dev/sdX for one of the new disks Here is the output for zpool list -v zmain :

The command without autoexpand=on worked: Where do we go from here? I'm still curious whether you see any risks in manually expanding the vdev from the CLI.

As expected, the command failed: Trying it without autoexpand=on now.

Okay, the command is running now. Should hopefully finish within the next 5 minutes. I'm also fairly confident the first command with autoexpand=on will fail.
