This is a procedure tries to find on disk unreachable extents and pretend they were already a part of bluefs log. If this gives proper crc, accept it. Fixes: https://tracker.ceph.com/issues/46552 Signed-off-by: Adam Kupczyk <akupczyk@redhat.com>
This ability only makes sense as a step that allows to perform fsck before commiting recovered bluefs log. Fixes: https://tracker.ceph.com/issues/46552 Signed-off-by: Adam Kupczyk <akupczyk@redhat.com>

Adds additional paragraph to ceph-bluestore-tool documentation, describing how to use *special* options --bluefs_replay_recovery and --bluefs_replay_recovery_disable_compact to recover large bluefs log. Fixes: https://tracker.ceph.com/issues/46552 Signed-off-by: Adam Kupczyk <akupczyk@redhat.com>

This is procedure that stems from https://tracker.ceph.com/issues/46195.
It was created and tested in Luminous, but now needs to be ported to all other ceph branches.
This fixes https://tracker.ceph.com/issues/46552.
