Hi Jan,
this doesn't look like RocksDB corruption but rather like some BlueStore
metadata inconsistency. Also assertion backtrace in the new log looks
completely different from the original one. So in an attempt to find any
systematic pattern I'd suggest to run fsck with verbose logging for
every failing OSD. Relevant command line:
CEPH_ARGS="--log-file osd.N.log --debug-bluestore 5/20"
bin/ceph-bluestore-tool --path <path-to-osd> --command fsck
Unlikely this will fix anything it's rather a way to collect logs to get
better insight.
Additionally you might want to run similar fsck for a couple of healthy
OSDs - curious if it succeeds as I have a feeling that the problem with
crashing OSDs had been hidden before the upgrade and revealed rather
than caused by it.
Thanks,
Igor

Hi Jan,
IIUC the attached log is for ceph-kvstore-tool, right?
Can you please share full OSD startup log as well?
Thanks,
Igor

Hello,
I've problem: my ceph cluster (3x mon nodes, 6x osd nodes, every
osd node have 12 rotational disk and one NVMe device for
bluestore DB). CEPH is installed by ceph orchestrator and have
bluefs storage on osd.
I've started process upgrade from version 17.2.6 to 18.2.1 by
invocating:
ceph orch upgrade start --ceph-version 18.2.1
After upgrade of mon and mgr processes orchestrator tried to
upgrade the first OSD node, but they are falling down.
I've stop the process of upgrade, but I have 1 osd node
completely down.
After upgrade I've got some error messages and I've found
/var/lib/ceph/crashxxxx directories, I attach to this message
files, which I've found here.
Please, can you advice, what now I can do? It seems, that rocksdb
is even non-compatible or corrupted :-(
Thanks in advance.
Sincerely
Jan Marek
