Upgrade from version 7.4-3 to 8.2-4 issues.

[davidoeol0]

Hello everyone,

During the migration of one of my Proxmox nodes from version 7.4-3 to version 8.2-4, when booting with the kernel 6.8.12-1 that comes with this latest version, the following error appears:

libceph: mon1 (1) 192.168.169.20:6789 socket closed ((con state V1_BANNER))
libceph: mon5 (1) 192.168.169.10:6789 socket closed ((con state V1_BANNER))
libceph: mon6 (1) 192.168.169.15:6789 socket closed ((con state V1_BANNER))[/CODE]
ceph: No mds server is up or the cluster is laggy
[FAILED] Failed to mount mnt-pve-cephfs.mount - /mnt/pve/cephfs[/CODE]

I have already tried several solutions found in other Proxmox forums, such as adding:

[mon]
mon_mds_skip_sanity = true

to the /etc/pve/ceph.conf file, or checking if all the Ceph packages are installed.

I'm including the output of the pveversion -v command from one of the nodes running version 8.2-4 and kernel 6.8.12-1.
