November 25, 20241 yr Hello, my data disk is suddenly showing as Unmountable: Unsupported or no file system. I have tried rebooting and replacing the sata cable with no luck. I ran xfs_repair with the -n option and the result is below. Can someone please provide guidance on how I can repair the issue without losing data? I have important files backed up, but would rather save this if possible. Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... 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... invalid start block 0 in record 0 of bno btree block 0/1 invalid start block 0 in record 255 of cnt btree block 0/2068651 agf_freeblks 108515719, counted 108515715 in ag 0 agi unlinked bucket 12 is 6212940 in ag 0 (inode=6212940) sb_icount 529856, counted 530112 sb_ifree 318, counted 95 sb_fdblocks 534365589, counted 533859465 - 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 bad nblocks 18446744073709551577 for inode 4701659101, would reset to 0 data fork in ino 4769315924 claims free block 596172975 - agno = 3 - process newly discovered inodes...

November 25, 20241 yr Community Expert Solution Run it again without -n, or nothing will be done, and if it asks for -L use it.
