I've been upgrading my cluster from 3.4 to 4.4, we use an iSCSI SAN for shared VM disk.
I noticed in the /var/log/messages on boot, this one message :
cgroup: new mount options do not match the existing superblock, will be ignored
It doesn't seem to be a problem, or cause a problem. The /etc/fstab is pretty basic :
root@strongest:~# cat /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext4 errors=remount-ro 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
So I don't think that there's any mismatched UUID due to the upgrade (fresh installs).
Is this a problem, or can it be safely ignored?
