BAlGaInTl Posted October 30, 2023 Share Posted October 30, 2023 (edited) I woke up this morning to all of my docker containers being gone. I dug in a bit more and found the following message for my Cache Pool where the appdata folder resides:  Unmountable: Unsupported or No File System  Not sure how this happened, and I'm not great at troubleshooting it. I'm not sure if something got corrupted?  I run the backup utility, and it ran last night, so I have all my appdata. Just wondering if there is a quick way to restore this?  I've attached my diagnostics dmitri-diagnostics-20231030-0654.zip  Edit: Changed from solved to add details below.

Solution JorgeB Posted October 30, 2023 Solution Share Posted October 30, 2023 If the log tree is the only problem this may help: Â btrfs rescue zero-log /dev/nvme0n1p1 Â Then restart the array. Quote Link to comment
BAlGaInTl Posted October 30, 2023 Author Share Posted October 30, 2023 Thanks. That worked.  Any insight as to 'why' this could happen? I don't see any issues with the drives themselves. Quote Link to comment

BAlGaInTl Posted November 9, 2023 Author Share Posted November 9, 2023 So I've been keeping an eye on it. It's happened two more times now over the last week.  I'm not sure how to track down why this is happening. The btrfs rescue command and restarting the array fixes it, but I don't want to keep having this issue. I'm at a loss on how to fix it permanently.  Any help is appreciated.

JorgeB Posted November 9, 2023 Share Posted November 9, 2023 If the problem is recurring suggest backing up and reformatting the pool. Quote Link to comment
BAlGaInTl Posted November 9, 2023 Author Share Posted November 9, 2023 Are there easy instructions for this, or would it be as simple as:  1 - move all my appdata and other cache shares to the array 2 - Kill the cache pool 3 - recreate the cache pool from scratch 4 - move everything back to the pool  ?  I'm sure I can do some searches on how to accomplish this exactly, but any help is appreciated.  Quote Link to comment
JorgeB Posted November 9, 2023 Share Posted November 9, 2023 Basically that's it, you can use the mover to move the data if you want, to re-format you can click on the pool, then "erase", then start array and re-format. Quote Link to comment
