I tried xfs_repair, on the drive with the bad file system, got the following root@NAS1:~# xfs_repair -v /dev/md9 Phase 1 - find and verify superblock... superblock read failed, offset 0, size 524288, ag 0, rval -1 fatal error -- Input/output error The Array starts and I can get to the remaining disk shares I am fine with losing the data on these 2 drives, Just need help getting the array back with the remaining drives. nas1-diagnostics-20190808-1522.zip Quote Link to comment
trurl Posted August 8, 2019 Share Posted August 8, 2019 Disk9 appears to have dropped offline. Check connections. Emulated disk5 is mounted. You should be able to rebuild it. Are you sure the disk is bad? Was it the Unassigned Device sdi? Quote Link to comment
trachal Posted August 8, 2019 Author Share Posted August 8, 2019 I checked the connections and swapped the cables. Disk 5 was failed Red X, and now is the Unassigned Device sdi Think that happened after a few reboots Quote Link to comment
JorgeB Posted August 8, 2019 Share Posted August 8, 2019 Both look like connection problems, check/replace cables for both, disk9 should then mount and just rebuild disk5, if the emulated disk still mounts. Quote Link to comment
trachal Posted August 8, 2019 Author Share Posted August 8, 2019 I Just replaced them both with 2 brand new cable. Got 9 back, added 5 back to the Array and it is rebuilding. Will see how it looks when all is done. Thanks for the help Quote Link to comment
