Syslog full of errors around sdc/brtfs

In the last two days I have also gotten the following emailed to me once a day. I am betting it is related:

 

Email Subject: cron for user root /sbin/fstrim -v /mnt/cache | logger &> /dev/null

Email Body: fstrim: /mnt/cache: FITRIM ioctl failed: Input/output error

Now my cache is starting read only after reboots (NOTHING in Unraid tells me this or that anything is wrong, I have to try to write to it via SSH to know this).

 

New diagnostics after the latest reboot.

 

I am guessing either one of the cache drives died (passing extended smart tests but looks like it might have a new unnallocated sector count that was successfully moved) or the btrfs corupted itself.

My whole cache seems to be hosed. BTRFS is doing some serious crunching on something right now after I removed the questionable drive from the cache pool. Will see if that ever comes back up up with a single drive or if I need to rebuild everything (I have backups!). Still don't know if the drive is bad though but suspecting it might be.

SMART shows some issues, so it might be the SSD, difficult to say for sure because the syslog only begins after the problem starts.
