Cache - Unmountable Disk Present...

Featured Replies

Restarted my Unraid Server after a power outage and found both my drives in my RAID 1, btrfs cache pool were listed as unmountable.

 

There seems to be some hesitancy with running checks/repairs with btrfs so I wanted to post my diagnostics and get some advice before doing something irreparable.

 

I'm unsure of the value what's in my cache. I believe I have a backup of what could be in there but I'd rather not have to rely on it. If there's a way to view the file listing before anything invasive happens that would be idea.

If this is still an issue this may help:

 

btrfs rescue zero-log /dev/sdd1

 

Then re-start array.
