Just FYI:
standalone ceph-bluestore-tool's quick-fix behaves pretty similar to the
action performed on start-up with bluestore_fsck_quick_fix_on_mount = true

Hi Stefan,
super thanks!
I found a quick-fix command in the help output:
# ceph-bluestore-tool -h
[...]
Positional options:
--command arg fsck, repair, quick-fix, bluefs-export,
bluefs-bdev-sizes, bluefs-bdev-expand,
bluefs-bdev-new-db, bluefs-bdev-new-wal,
bluefs-bdev-migrate, show-label, set-label-key,
rm-label-key, prime-osd-dir, bluefs-log-dump,
free-dump, free-score, bluefs-stats
but its not documented in https://docs.ceph.com/en/octopus/man/8/ceph-bluestore-tool/. I guess I will stick with the tested command "repair". Nothing I found mentions what exactly is executed on start-up with bluestore_fsck_quick_fix_on_mount = true.
Thanks for your quick answer!
Best regards,

Hi Igor and Stefan,
thanks a lot for your help! Our cluster is almost finished with recovery and I would like to switch to off-line conversion of the SSD OSDs. In one of Stefan's I coud find the command for manual compaction:
ceph-kvstore-tool bluestore-kv "/var/lib/ceph/osd/ceph-${OSD_ID}" compact
Unfortunately, I can't find the command for performing the omap conversion. It is not mentioned here https://docs.ceph.com/en/quincy/releases/octopus/#upgrading-from-mimic-or-nautilus even though it does mention the option to skip conversion in step 5. How to continue with an off-line conversion is not mentioned. I know it has been posted before, but I seem unable to find it on this list. If someone could send me the command, I would be most grateful.
for osd in `ls /var/lib/ceph/osd/`; do ceph-bluestore-tool repair --path
/var/lib/ceph/osd/$osd;done
That's what I use.
Gr. Stefan
