There is no need ibthink. I did all 12 of my cluster at home plus all the work proxmox with no issues
It might be safer to wait, one of my IRL friends ran into an issue, and I saw some others post about it on the Proxmox forums:
TASK ERROR: activating LV 'pve/data' failed: Check of pool pve/data failed (status:64). Manual repair required!I think I didn’t run into that error because I flattened my LVM kinda, but if I hadn’t customized my setup maybe I would have run into that too.
Its in the release upgrade notes. There isvone command to run if you are doing lvm. All my stuff is zfs or ceph so i never ran into it
