Dear Cephers, I just had one Ceph osd node (Luminous 12.2.13) power-loss unexpectedly, and after restarting that node, two OSDs out of 10 can not be started, issuing the following errors (see below image), in particular, i see Rocksdb: Corruption: missing start of fragmented record(1) Bluestore(/var/lib/ceph/osd/osd-21) _open_db erroring opening db: ... **ERROR: OSD init failed: (5) Input/output error I checked the db/val SSDs, and they are working fine. So I am wondering the following 1) Is there a method to restore the OSDs? 2) what could be the potential causes of the corrupted db/wal? The db/wal SSDs have PLP and not been damaged during the power loss Your help would be highly appreciated. best regards, samuel huxiaoyu@xxxxxxxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
