This is again about our bad cluster, with too much objects, and the hdd
OSDs have a DB device that is (much) too small (e.g. 20 GB, i.e. 3 GB
usable). Now several OSDs do not come up any more.
Typical error message:
/build/ceph-14.2.8/src/os/bluestore/BlueFS.cc: 2261: FAILED
ceph_assert(h->file->fnode.ino != 1)
Also just tried to add a few GB to the DB device (lvextend,
ceph-bluestore-tool bluefs-bdev-expand), but this also crashes, also
with this message.
Options that helped us before (thanks Wido :-) do not help here, e.g.
CEPH_ARGS="--bluestore-rocksdb-options compaction_readahead_size=0"
ceph-kvstore-tool bluestore-kv /var/lib/ceph/osd/ceph-$OSD compact
Any ideas that I could try to save these OSDs?
Cheers
Harry
