+BlueFS log rescue
+=====================
+
+Some versions of BlueStore were susceptible to BlueFS log growing extremaly large -
+beyond the point of making booting OSD impossible. This state is indicated by
+booting that takes very long and fails in _replay function.
+
+This can be fixed by::
+ ceph-bluestore-tool fsck --path *osd path* --bluefs_replay_recovery=true
+
+It is advised to first check if rescue process would be successfull::
+ ceph-bluestore-tool fsck --path *osd path* \
+ --bluefs_replay_recovery=true --bluefs_replay_recovery_disable_compact=true
+
+If above fsck is successfull fix procedure can be applied.
