[PVE-User] PVE 7 Ceph 16.2.6 osd crash

hello Eneko
are all your ceph nodes time synced ?
PLS check chrony and drift time
# ceph time-sync-status

in case you have new spare disk and free slot, try to add new OSD and 
stabilize ceph cluster
in case you do not have free slot (and you are sure that it failed) you 
have to replace it
https://docs.ceph.com/en/latest/rados/operations/add-or-rm-osds/#replacing-an-osd

before any changes identify disk and OSD status
list disk bay at server # pvs
# ceph osd tree
# ceph device ls
# ceph-volume lvm list > osd-lvm-list-202110XX

BTW we started with ceph cluster here in June, so sorry i am beginner 
with ceph
