Description
Hi !
We have done an (almost) successful upgrade to Ceph Luminous 12.2.5.
The Cluster becomes almost healthy. But very shortly before that, One OSD crashes (osd.130).
We could already identify a faulty placement group.
Surprisingly this PG is up&running on 2 other servers without any problem.
With "ceph pg dump" we can see, that the last column (SNAPTRIMQ_LEN) of PG 5.9b is "27826
", and not zero like on the other pgs...
To solve the Problem, we already purged all snapshots of the rbd Pool. (ID=5)
Then we increases verbosity, cache Size and throttle_bytes in ceph.conf like this :
[osd.130]
debug bluestore = 20
debug osd = 20
bluestore_throttle_bytes = 0
bluestore_throttle_deferred_bytes = 0
debug throttle = 10
bluestore_cache_size_hdd = 10737418240
bluestore_cache_size_ssd = 10737418240
Then we deleted the PG from the crashing OSD :
ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-130/ --pgid 5.9b --op remove --force
But again, the OSD crashes.
/build/ceph-12.2.5/src/osd/PrimaryLogPG.cc: 358: FAILED assert(p != recovery_info.ss.clone_snaps.end())
What can we do to bring the PG up on all 3 OSDs ?

Updated by Sage Weil almost 6 years ago
- Status changed from New to 12
- Priority changed from Normal to High
The second crash appears to be in the recovery path. are all of the other osds upgraded at this point?
Updated by Siegfried Hoellrigl almost 6 years ago
Yes. 12.2.5. But most of them still filestore. (OSD.130 is a bluestore already)

- Subject changed from Upgrade from Jewel 10.2.10 to Luminous 12.2.5 has broken snaptrim at a placement group. OSD Crashes shortly before Cluster becomes healthy to jewel->luminous: osd/PrimaryLogPG.cc: 358: FAILED assert(p != recovery_info.ss.clone_snaps.end())
Updated by Siegfried Hoellrigl almost 6 years ago
Hi !
Is there any workaround to fix the problem ?
Updated by Siegfried Hoellrigl almost 6 years ago
Hi !
We have now recompiled ceph-12.2.5 with the Patch from https://tracker.ceph.com/issues/24396
and started this OSD.130 with the new binary.
-> Cluster became healthy.
Is there any Roadmap when this patch will be in the official stable release of ceph ?
Updated by Siegfried Hoellrigl almost 6 years ago
Hi !
After a while (Cluster was HEALTH_OK) - there started the scrubbing (or deep-scrubbing ?).
Now we have a scub error.
The strange thing is, that "data_digest" on the primary and on one OSD seem to be the same.
("0xbac4384a"). And on the new OSD with the Patch applied - it is different.
How can we further troubleshoot/fix this ?
Is this related somehow to https://tracker.ceph.com/issues/21388 ?

Hi !
In the meantime we have upgraded to ceph 12.2.8.
In ceph.conf "osd distrust data digest = true" is still set.
Same PG has still problems.
It seems to cause an OSD Crash when we do a "ceph pg repair".
In the logs we can see :
