Hi, I'm encountering a data disaster. I have a ceph cluster with 145 osd. The data center had a power problem yesterday, and all of the ceph nodes were down. But now I find that 6 disks(xfs) in 4 nodes have data corruption. Some disks are unable to mount, and some disks have IO errors in syslog. mount: Structure needs cleaning xfs_log_forece: error 5 returned I tried to repair one with xfs_repair -L /dev/sdx1, but the ceph-osd reported a leveldb error: Error initializing leveldb: Corruption: checksum mismatch I cannot start the 6 osds and 22 pgs is down. This is really a tragedy for me. Can you give me some idea to recovery the xfs? Thanks very much! _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
