Cache Drives unmountable following reboot

My HA VM had a few issues so I rebooted my Unraid system. Once back online, my cache drives have been showing as "Unmountable: Unsupported or no file system".

 

I had made no changes to the system or drives, it just seemed to happen. 

 

Any advice, please? Diagnostics attached.

    btrfs rescue zero-log /dev/sde1

     

    Then restart the array and post new diags.

    updated diagnostics after running the command.
    I also needed to run umount /mnt/cache_recover as "/dev/sde1 is currently mounted"

     

    after doing both of these things, the drives are back and docker & VMs have returned. 

     

    Reliably do you think? Or deep issue that needs fixing?

    Looks OK, but recommend scrubbing the pool, since before there were some checksum errors logged, there are also a few corruption errors on the docker image, any issues with it, better to just recreate it.
