Homerr Posted December 5, 2021 Share Posted December 5, 2021 (edited) We had a power outage in our neighborhood Friday. I restarted the server that night and it ran a parity check which ended last night, it seemed everything was okay. I was then in the case late last night replacing a case fan (routine, not related to the power outage) and booted the server back up. It was late and I thought everything was okay initially. This morning I noticed that Disk 2 in unmountable. I did shutdown and reseat Disk 2's drive cage and unplug/plug the SATA cable that goes to it's backplane. I did not replace the cable as of yet. This drive is one of the 4 in my system connected to the motherboard via SATA, the others are on an LSI 9201-16i card. I do have a 12tb disk that I can use if needed and I have one spare port on the 16i setup. I did do some searching on this topic and there were serveral paths taken, I'm not sure exactly what I should do here. I don't really know the commands in Linux but can follow directions. Can anyone help me out here? unraid-diagnostics-20211205-0800.zip Edited December 5, 2021 by Homerr Quote Link to comment

Homerr Posted December 5, 2021 Author Share Posted December 5, 2021 Disk is XFS, I restarted in Maintenance mode and ran the check on the disk, result below. I'm at step 2 of Repairing a File System - "Add any additional parameters to the Options field required that are suggested from the check phase. If not sure then ask in the forum. The Help build into the GUI can provide guidance on what options might be applicable." Is it recommended to add any parameters? (Doing this via GUI, btw.) Step 4 notes a -L option. 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... block (7,74328029-74353290) multiply claimed by cnt space tree, state - 2 block (7,74169449-74170249) multiply claimed by cnt space tree, state - 2 block (7,74169449-74170249) multiply claimed by cnt space tree, state - 2 invalid start block 0 in record 51 of cnt btree block 7/2 invalid start block 0 in record 52 of cnt btree block 7/2 invalid start block 0 in record 53 of cnt btree block 7/2 invalid start block 0 in record 54 of cnt btree block 7/2 invalid start block 0 in record 55 of cnt btree block 7/2 invalid start block 0 in record 56 of cnt btree block 7/2 invalid start block 0 in record 57 of cnt btree block 7/2 invalid start block 0 in record 58 of cnt btree block 7/2 invalid start block 0 in record 59 of cnt btree block 7/2 agf_freeblks 207015525, counted 194421230 in ag 7 agi unlinked bucket 39 is 130200423 in ag 7 (inode=15162585959) sb_ifree 8809, counted 8862 sb_fdblocks 576670704, counted 604659013 - 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 data fork in ino 15040730579 claims free block 1953203817 data fork in ino 15162585949 claims free block 1953077194 - agno = 8 - agno = 9 - process newly discovered inodes...

Only if after removing the -n it suggests to add the -L Quote Link to comment
Homerr Posted December 5, 2021 Author Share Posted December 5, 2021 Thenks Squid! I ran it, no errors and restarted in normal array mode and everything looks to be as it should. Quote Link to comment
