Good Day,

I started noticing the following alerts when moving disks between LUNS in my environment

After running lvs -a PVE03

I noticed a snapshot I could not receive from the GUI OR CLI

I started moving disks off PVE03 to another LUN as my intention is to destroy PVE03, check the disks and rebuild it if the disks are fine, these issues could have occurred as PVE03 Thin LV ran out of space recently after taking snapshots and backups were made.

I tried moving disk of VM 157 ( vm-157-disk-0 ), I leave the checkbox untick to delete the source intentionally though..

After 3 hours the dis move completes but fails with the below error.

I have tried this 3 times now, the same result.

Please advise how I can fix the issue OR underlying issue on PVE03 OR move the disks in another way as I don't mind destroying PVE03 and rebuilding it.

Thanks

Hi,

I have managed to migrate most of the VM's off from my LUN PVE03, I cannot migrate one of my disks.

How do I fix/repair this issue

After reading some forums a repair needs to be run on the LV

I have deactivated the LV's on PVE03
Deactivated PVE03/PVE03
Ran the following command

root@pve-205:~# lvconvert --repair PVE03/PVE03

it's on the following line for the last 12 hours

Using default stripesize 64.00 KiB.


I am not sure if anything is happening?

PVE03 is a 3.64Tb SSD LUN

Regards
