BTRFS error on cache drive

[ipreferpie]

So I discovered today that my docker containers won't load and thought that I needed to delete/recreate the image and all would be ok. But deleting the image from settings and then on bash didn't work. I then went to take a look at my cache pool and that's when things looked iffy. Here's the cache disk log:

Then strange thing is that I have 18,446,744,073,703,520,256 reads and 18,446,744,073,702,512,640 writes. The SSD temperature is no longer displayed and replaced with a "*". But unRAID tells me that the device is in normal operation and active. Something looks seriously wrong and I seem to be only do read-only on the files located in the cache. Any suggestions on my next step? Many thanks!

I've had this happen to me twice now.  I've seen suggestions that it could be as simple as a bad SATA cable, but running in an R710 makes it difficult for me to test that at this time. (proprietary SATA cable and SSD sled for the optical bay)  Your drive is readable, create a space on the array, and copy everything over as a backup.  Reboot.  I found that typically a reboot reset the error state and everything was happy.  The first time I swapped the drive and later learned that there was no need as the drive was still good.  Thankfully I had access to a spare.

 

---aaaandd mine just hosed up again too.
