Dear Cephers,
We are planning the upgrade of out Ceph cluster, version Mimic 13.2.10. (3Mons, 3MGRs, 181OSD, 2MSDs, 2 RGW)
Cluster is healthy and all the pools are running size 3 min_size 2.
This is an old cluster implementation that has been upgraded from firefly (There are still a clouple OSDs under filestore about 8 small OSD).
Then I have a couple of questions:
- Can we update directly from mimic to Octopus or should bw step by step ?
- Can we maintain the filestore OSDs or is better to delete migrate this OSDs?
- MIgration order is MONs/MGRs, OSDs, MDS, RGW?
- Can be the OSDs up during the migration? Should be all of them restarted at the same time?
I suggest you first check upgrade notes:
For Nautilus:
https://docs.ceph.com/en/latest/releases/nautilus/#upgrading-from-mimic-or-luminous
For Octopus:
https://docs.ceph.com/en/latest/releases/octopus/#upgrading-from-mimic-or-nautilus
For Pacific: (not supported upgrading directly from Mimic)
https://docs.ceph.com/en/latest/releases/pacific/#upgrading-from-octopus-or-nautilus
Seems, you can upgrade first to Nautilus, then you can choose to upgrade
to Octopus or Pacific from there.
Cheers
