August 7, 20196 yr Hi, I got the error (Unmountable: No file system) on Disk 2 the same time when Disk 1 was rebuilding. (After facing this issue) I waited for Disk 1 rebuild to finish, then restart the array/server, but the Unmountable message on Disk 2 still appears. I went through this documentation and executed this command (-nv) in maintenance mode and got the below response: Phase 1 - find and verify superblock... - block cache size set to 707800 entries Phase 2 - using internal log - zero log... zero_log: head block 654523 tail block 654519 ALERT: The filesystem has valuable metadata changes in a log which is being ignored because the -n option was used. Expect spurious inconsistencies which may be resolved by first mounting the filesystem to replay the log. - scan filesystem freespace and inode maps... - found root inode chunk Phase 3 - for each AG... - scan (but don't clear) agi unlinked lists... - process known inodes and perform inode discovery... - agno = 0 - agno = 1 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - process newly discovered inodes... Phase 4 - check for duplicate blocks... - setting up duplicate extent list... - check for inodes claiming duplicate blocks... - agno = 0 - agno = 3 - agno = 6 - agno = 1 - agno = 2 - agno = 4 - agno = 7 - agno = 5 No modify flag set, skipping phase 5 Phase 6 - check inode connectivity... - traversing filesystem ... - agno = 0 - agno = 1 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - traversal finished ... - moving disconnected inodes to lost+found ... Phase 7 - verify link counts... Maximum metadata LSN (1:654601) is ahead of log (1:654523). Would format log to cycle 4. No modify flag set, skipping filesystem flush and exiting.

August 7, 20196 yr Community Expert You should rerun the xfs_repair without the -n option but add the -L option. After doing that the disk should be mountable again.
