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
