[ceph-users] Corrupted block.db for osd. How to extract particular PG from that osd?

Hello cephers! We're lost block.db file for one of our osd. This results in down osd and incomplete PG. Block file from osd, which symlinks to particular /dev folder is live and correct. My main question is there any thereoretical possibility to extract particular PG from osd which block.db device has been lost? Is there any way I can make it using ceph-objectstore-tool or ceph-bluestore-tool? We're running ceph version 12.2.12 -- Very truly yours, Kalinkin Alexey Research fellow of Epigenetic lab, RCMG.
