Sousapro Posted March 30, 2020 Share Posted March 30, 2020 (edited) Hello, I have a Unraid system that is constantly generating read only file system errors in docker after being online for a short period of time. troubleshooting steps so far: checked 2x Cache SSD BTRFS with a scrub (no errors found) removed and rebuilt docker.img XFS_Repair on all XFS volumes in array maintenance mode all SMART data is showing green Logs are attached to post. I'm flexible with any needed troubleshooting but this one has kind of stumped me. this occurred after a drive (that had no data on it) started showing pre-fail and was replaced with cleared new drive. thanks for the help and looking at this post. edit: I recreated docker one more time and made sure that I'm running my minimal set of images and that none of them are privileged at this time. going to run it like this for a few hours and see if the error recurs. edit 2: failed within 15 minutes to read only file system. unraid-diagnostics-20200330-1840.zip Edited April 5, 2020 by Sousapro Quote Link to comment
JorgeB Posted March 31, 2020 Share Posted March 31, 2020 Cache filesystem has issues, best bet is to backup all data, re-format the pool and restore the data. Quote Link to comment
Sousapro Posted April 5, 2020 Author Share Posted April 5, 2020 Thanks @johnnie.black, this resolved it. I'm a little concerned about BTRFS Scrub not finding anything before but drive health is good and the array has behaved normally since rebuilding the cache drives. Quote Link to comment
