rutherford Posted June 26, 2020 Share Posted June 26, 2020 I've had things come up with this drive, MD5, three times now. I keep ending up with wayward files, random pictures, a few videos in the Lost&Found folder the xfs_repair creates. Is it time to replace this drive? Or perhaps I have something else that might be the source of these errors? Thanks. unRaid Log excerpt Jun 25 13:31:38 rubble kernel: XFS (md5): metadata I/O error in "xfs_trans_read_buf_map" at daddr 0x28d64b418 len 32 error 117 Jun 25 13:31:38 rubble kernel: XFS (md5): xfs_imap_to_bp: xfs_trans_read_buf() returned error -117.

Did the xfs_repair status, here are hastebin results Many entries in there. Unfortunate. If I replace the drive, will that fix any of this stuff? I have a hot standby in the server ready to replace this drive. I suspect I'll have to run this repair, THEN replace the drive. Or the errors will simply get copied to the new drive, and I'll have to replace it anyhow. Any help would be terrific, thanks! rubble-smart-20200625-1924 disk 5.zip rubble-diagnostics-20200625-1914.zip Quote Link to comment
rutherford Posted June 26, 2020 Author Share Posted June 26, 2020 (edited) did the xfs-repair. Lost+found is 4GB comprised of 18689 files. FML root@rubble:/mnt/user/lost+found# find . -type f | wc -l 18689 reassigned Disk 5 to my pre-cleared hot standby. Rebuilding drive. But all those files in the lost+found. There is no way I'm going to even make a dent in figuring out what they are, where they go. Isn't this exactly what the RAID is supposed to protect? Oh, my files are gone, they just jumbled beyond any recognition. Is that right?! Edited June 26, 2020 by dkerlee Quote Link to comment
JorgeB Posted June 26, 2020 Share Posted June 26, 2020 Unraid can't protect against filesystem corruption, if corruption keeps happening always on the same disk it might be a good idea to re-format and create a new filesystem, but you'd need to backup all data there first, if corruption is happening on multiple disks without an apparent reason there's likely some hardware problem, like bad RAM, controller, etc. 1 Quote Link to comment
rutherford Posted June 27, 2020 Author Share Posted June 27, 2020 Thank you very much! A shame with that corruption thing. I like the idea of not having to throw away this 4 year old 8TB drive. Can you direct me to some instructions for what you mentioned there? 18 hours ago, johnnie.black said: re-format and create a new filesystem, but you'd need to backup all data there first Is it as easy as limetech mentions in this thread? As I have a hot standby drive option, I've already removed the old Disk 5 (sdg) drive, and the array is rebuilding new Disk 5 (sdf). Would a deeper SMART scan identify any issues with it? Finished the rebuild on to the new Disk 5 sdf. Seems to have worked w/out a flaw. The old sdg is still being precleared. How can I figure if it's safe to use in the future? Quote Link to comment

Disk looks healthy, most likely filesystem in not a disk problem. 4 hours ago, dkerlee said: Is it as easy as limetech mentions in this thread? Yes, but first you need to backup any data there, then restore it after the format. Quote Link to comment
