Hi Samuel, we try to fix it in trick way. we check all rbd_data chunks from logs (OSD) which are affected, then query rbd info to compare which rbd consist bad rbd_data, after that we mount this rbd as rbd0, create empty rbd, and DD all info from bad volume to new one.
But after that - scrub errors growing... Was 15 errors.. .Now 35... We laos
try to out OSD which was lead, but after rebalancing this 2 pgs still have
35 scrub errors...
ceph osd getmap -o <outfile> - attached
