mbezzo Posted July 20, 2018 Share Posted July 20, 2018 (edited) Hi All, New to unRAID and have been spending the last few weeks getting everything setup and my data moved over with great success. It's been going really well and I'm really liking the product! That being said, as of this morning I'm getting just unending errors like this: Jul 20 15:15:10 unRAID kernel: BTRFS critical (device sdi1): corrupt node, bad key order: block=164267491328, root=1, slot=44 I'm trying to stop the array, but it won't stop so I guess I'm just not really sure what the next steps are for me to get this resolved. I'm attaching the diagnostics. Any help or pointers would be greatly appreciated! Thanks, Matt unraid-diagnostics-20180720-1515.zip Edited July 20, 2018 by mbezzo typos Quote Link to comment
mbezzo Posted July 21, 2018 Author Share Posted July 21, 2018 alright, so it seems there's unrecoverable errors on the cache drive. how can I delete my cache and recreate it? Quote Link to comment
JorgeB Posted July 21, 2018 Share Posted July 21, 2018 You can run a scrub, if there are uncorrectable errors then reformat the pool. Quote Link to comment
mbezzo Posted July 21, 2018 Author Share Posted July 21, 2018 thanks - scrub can't fix a few, can you point me to directions on reformatting the pool? I can't seem to find that piece! Thanks! Quote Link to comment
mbezzo Posted July 21, 2018 Author Share Posted July 21, 2018 appdata share is so messed up. If I mount it and look around there's only a few of my docker container's directories. BUT, if I use command line to cd to a docker that isn't visible... it works. For some, not all. Any tricks on how to recover? I'm assuming it's gonna be nuke and start over... I so don't understand what happened here but man, a painful lesson! root@unRAID:/mnt/user/appdata# ls -al total 36 drwxrwxrwx 1 nobody users 228 Jul 20 22:39 ./ drwxrwxrwx 1 nobody users 100 Jul 20 17:59 ../ -rw-rw-rw-+ 1 nobody users 6148 Jul 21 12:33 .DS_Store -r--r--r--+ 1 nobody users 0 Jul 1 13:04 .com.bombich.ccc.casetest -r--r--r--+ 1 nobody users 0 Jun 30 14:23 .com.bombich.ccchelper.casetest drwxrwxrwx 1 nobody users 35 Jul 1 09:58 DDClient/ drwxrwxrwx 1 nobody users 18 Jun 24 12:39 DiskSpeed/ drwxrwxrwx 1 nobody users 54 Jul 21 09:17 binhex-radarr/ drwxrwxrwx 1 nobody users 80 Jul 20 14:22 binhex-sonarr/ drwxrwxrwx 1 nobody users 6 Jun 30 13:32 data/ drwxrwxr-x 1 nobody users 78 Jul 20 22:39 krusader/ drwxrwxrwx 1 nobody users 197 Jul 20 22:09 letsencrypt/ drwxrwxrwx 1 nobody users 6 Jul 20 22:07 letsencryptold/ drwxrwxrwx 1 nobody users 33 Jun 30 09:59 nzbget/ drwxrwxrwx 1 nobody users 88 Jul 20 22:52 ombi/ drwxrwxrwx 1 nobody users 20 Jul 2 17:35 organizr/ drwxrwxrwx 1 nobody users 24 Jul 21 12:31 tautulli/ root@unRAID:/mnt/user/appdata# cd PlexMediaServer root@unRAID:/mnt/user/appdata/PlexMediaServer# ls -al total 0 drwxrwxrwx 1 nobody users 14 Jul 16 21:00 ./ drwxrwxrwx 1 nobody users 228 Jul 20 22:39 ../ drwxr-xr-x 1 root root 38 Jul 16 21:00 Library/ How is this even possible!? If it is nuke and start over - what's the best way to do that? Simply delete the appdata share and recreate it? Appreciate the help! Quote Link to comment
JorgeB Posted July 22, 2018 Share Posted July 22, 2018 You can try btrfs restore if you need to save some data. When all data is backed up just wipe all the disks with blkdiscard, stop the array and run: blkdiscard /dev/sdX Replace X with each device, then start the array and reformat the pool.
