Cache Pool Failure - BTRFS filesystem unmountable

My server just took a big crap. It's been working fine but the last few days quite a few errors have popped up.


Recently it would just be totally unresponsive on the network. I could still access it from console but nothing else. I usually would just reboot it from there and all is good. Last week my docker image got corrupted so I had to start a new one but no it looks like my whole cache is all wonky.


I just rebooted and am getting these errors and it says BTRFS filesystem is unmountable. It looks like the smart on one of the cache drives is reporting a Reallocated sector count of 10 and CRC error count of 2. Nothing like critical. I was going to replace that soon but did it die on me?

How should I proceed?

Update: I ran

btrfs rescue zero-log /dev/sdf1

and it fixed it to be able to mount but what would cause this in the first place?
