curiouskid Posted October 4, 2017 Share Posted October 4, 2017 One of my drive seem to have failed but it's passing smart. However, when I tried to start array, I notice following errors in system log and it has not started array for last 30 mins.

I even tried replaceing power cable by borrowing it form SSD and it didn't help either. Array doesn't start for me to run xfs_repair -v /dev/sdc1 Can someone please help? Quote Link to comment
tdallen Posted October 4, 2017 Share Posted October 4, 2017 I'd suggest posting your full diagnostics, Tools->Diagnostics. Quote Link to comment
BobPhoenix Posted October 5, 2017 Share Posted October 5, 2017 16 hours ago, curiouskid said: ata10.01: limiting speed to UDMA/100:PIO4 This make me think you might have some of your MB ports set to PATA mode rather than SATA/AHCI mode. So you may have multiple problems if my suspicion is correct. Definitely post the WHOLE diagnostics as that will help those that can read logs better then I can an idea of any and all problems you might have and whether I'm even close to being correct above or not.

curiouskid Posted October 5, 2017 Author Share Posted October 5, 2017 Attached here are diagnostic file. My data drive is now unmountable. xfs_repair didn't help either. I am getting the feeling that i my data is in extreme danger. Parity is still valid. So, if someone can advice me on how to rebuild it, I would appreciate. root@UnRaid:~# xfs_repair -v /dev/sdc1 Phase 1 - find and verify superblock... - block cache size set to 660784 entries Phase 2 - using internal log - zero log... zero_log: head block 91463 tail block 91448 ERROR: The filesystem has valuable metadata changes in a log which needs to be replayed. Mount the filesystem to replay the log, and unmount it before re-running xfs_repair. If you are unable to mount the filesystem, then use the -L option to destroy the log and attempt a repair. Note that destroying the log may cause corruption -- please attempt a mount of the filesystem before doing this. unraid-diagnostics-20171005-1606.zip Quote Link to comment
itimpi Posted October 6, 2017 Share Posted October 6, 2017 It is quite normal to get that message. When you do you just need to run xfs_repair with the -L option. It is very rare for there to be any data loss as a result and even if it there was it would only affect the last file written. Another option is to do a manual mount/umount of the disk (which clears the need for the -L flag) before running the xfs_repair. Quote Link to comment
