Hi Simon,
your analysis is correct, you've stepped into an unexpected state for
BlueFS log.
This is the second occurrence of the issue, the first one is mentioned at
https://tracker.ceph.com/issues/45519
Looking if we can get out of this state and how to fix that...
Thanks,
Igor

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)
The context of that line is "we should never run out of log space here":
// previously allocated extents.
bool must_dirty = false;
if (allocated < offset + length) {
// we should never run out of log space here; see the min runway check
// in _flush_and_sync_log.
ceph_assert(h->file->fnode.ino != 1);
So I guess we are violating that "should", and the Bluestore code
doesn't handle that case. And the "min runway" check may not be
reliable. Should we file a bug?
Again, help on how to proceed would be greatly appreciated...
