[ceph-users] crashing OSDs: ceph_assert(h->file->fnode.ino != 1)

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
