Hi! In case of scub error we get some PGs in inconsistent state. What is a best method to check, what RBD volumes are mapped into this inconsistent PG?
Now we invent a long and not easy way to to this: - from 'ceph health detail' we take PGnums in inconsistent state - we check logs for errors, associated with this PG, and take 'rbd_volume' prefix from log line - for all RBD volumes in pool we run 'rbd -p <pool> info <volume>' and check 'block_name_prefix' in output. So, after all, we get a volume name, that potentially have problems due to inconsistency. Is this the right way? Can RBD 'block_name_prefix' maps on two or more PGs, so our method to discover RBD volume <-> PG number are incomplete? How could you determine the impact from inconsistent PGs on data integrity (in terms of affected VM-over-RBD images)? Thanks!
