[Update] Cache Pool - Unmountable: Unsupported or No File System


Go to solution Solved by JorgeB,

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

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.

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.
