ZFS Pool not starting

[SeaWee]

Hi,

my mirrored ZFS drive does not start. This is where I have all my "important" files

Normally both Main_Storage and Single_Storage loads fine



As you can see, the Main_Storage has a question mark on it.

Also on the ZFS tab only one shows up.



On the Storage tab it looks as if there...



And on the Disks overview, the disks for the Single_Main also appears.



Can anyone help to get this ZFS Pool running again, please?

 

[leesteken]

Please show the settings for Main_Storage, what do you see under Disks > ZFS and what is the output of zpool status?

 

[alexskysilk]

please post output of
lsblk
zpool status
edit @leesteken jinx

As mentioned, the Disks - ZFS show just the "other" ZFS

And lsblk is here

So - just to be clear. I have 3 x 3 TB disk... 2 are in the "MAIN_Storage"....and the 3rd in the "SINGLE_Storage"

 

[leesteken]

What does zpool import show?

Just tried

journalctl -xe

Seems it is constantly trying this pool...

 

[leesteken]

It appears to be completely gone. I have not experience or idea how to get it back. Did those drives get wiped somehow?

I hope not...

under /dev/disk/by-id the disks are there...



but then under label they are not...

Me too.

That does not look like ZFS but something else. I don't know why I assumed that your Main_Storage was a ZFS pool.

Atleast there are three 3TB HDDs with the typical ZFS partitioning (big partition 1 + small partition 9). So by looking at the partitions all 3 disks were used as whole unbootable ZFS disks.

 

[SeaWee]

But Main_Storage is supposed to be a ZFS consisting of 2 x 3TB disks...

I noticed something here:

 

[leesteken]

Can you please double click on the Main_Storage in the Datacenter > Storage GUi or attach /etc/pve/storage.cfg? This will show us how you configured that storage. Are you passing through LVM logical volumes or disk partitions to a FreeNAS that uses ZFS by any chance?

 

[SeaWee]

Here you go:



cfg file

I used these ZFS' in openmediavault...I made an error in omv and wanted to restore it from a backup...

So what I did, I deleted the VM first...and maybe this is the issue....I crossed the 2 lower boxes

No filesystem supports being used on the Proxmox host and a VM (at the same time). Was your openmediavault a VM or a container?

It was a VM - has been running fine with this ZFS for a year...

 

[Dunuin]

So maybe your PVE can't import the pool because it is already imported in the OMV VM in cse you used disk passthrough?
Like leesteken already said, you can't/shouldn't use the same pool for host and guest.
