One of host that runs ceph-mon went offline and then monitor become out of quorum state. To fix that I deployed a new ceph-mon unit and removed failing one.
Ceph successfully created new monitor however following warning raised in Ceph status:
client is using insecure global_id reclaim
Any suggestion to fix that warning?
Note: we are using focal ussuri.
Your new ceph-mon unit is likely patched to a version of Ceph which now supports secure Global ID Reclaim.
Check under “Fix Details” number 3 notes that upgraded ceph-mons will start showing the message when it detects older client versions attached.
This CVE will walk you through addressing this. I would recommend starting with checking ceph versions and performing package upgrades and service restarts to get the cluster up to the same level, then addressing the alert.
