Dear everyone, during a very risky process or rebuilding my OSDs to relocate their WAL&DBs onto NVMe SSD partitions, I created a situation where 2 of 3 OSDs of jerasure 2+1 pool had become destroyed, without waiting for complete rebuild of their respective PGs on newly-created OSDs. And now I have an incomplete PG, looking like this : [WRN] PG_AVAILABILITY: Reduced data availability: 1 pg inactive, 1 pg incomplete pg 1.90 is incomplete, acting [2,3,5] (reducing pool jerasure21 min_size from 2 may help; search ceph.com/docs for 'incomplete') PG OBJECTS DEGRADED MISPLACED UNFOUND BYTES OMAP_BYTES* OMAP_KEYS* LOG STATE SINCE VERSION REPORTED UP ACTING SCRUB_STAMP DEEP_SCRUB_STAMP 1.90 0 0 0 0 0 0 0 0 incomplete 47m 0'0 223998:104494 [2,3,5]p2 [2,3,5]p2 2020-04-01T13:22:08.983764+0300 2020-03-29T18:36:21.037198+0300 This corrupted some (or maybe all) of my iSCSI RBD targets, and now I would like to determine what of them will have to be dropped & recreated so as not to refer to these incomplete objects. Is there a known recipe or scenario to do that ? Also I would like to know if anything special needs to be done to the incomplete PG to make it complete and usable again. Thanks in advance for your help.
