I did it only on MON servers. OSDs are on centos 7. Process was:
1. stop mon&mgr
2. backup /var/lib/ceph
3. reinstall server as centos 8 and install ceph nautilus
4. restore /var/lib/ceph and start mo&mgr
5. wait few days
6. upgrade mon&mgr to octopus

How did you do the upgrade from centos7 to centos8? I assume you kept osd config's etc?
upgrading nautilus (14.2.22) to octopus (15.2.14) on centos7 (Mon/Mgr
were additionally migrated to centos8 beforehand). Each day I upgraded
one host and after all osd's were up, I manually compacted them one
by
one. Today (8 hosts upgraded, 7 still to go) I started
getting errors like "Possible data damage: 1 pg inconsistent".
For the
first time it was "acting [56,58,62]" but I thought "OK"
in osd.62 logs
there are many lines like "osd.62 39892 class rgw_gc open got (1)
Operation not permitted" Maybe rgw did not cleaned some omaps
properly,
Is the rgw still nautilus? What about trying with rgw of octopus?
and ceph did not noticed it until scrub happened. But now I have got
"acting [56,57,58]" and none of this osd's has those errors
with rgw_gc
in logs. All affected osd's are octopus 15.2.14 on NVMe hosting
default.rgw.buckets.index pool. Has anyone experience with this
problem? Any help appreciated.
