Hello,
I recently had one of my cache drives fail in Unraid.
I have (had) two 1TB SSDs installed for a cache drive pool and one failed. So far the failed drive won't recognize in unraid or on another PC.
I have disabled the Docker Service and removed the remaining SSD from the pool. Before I removed it from the pool the SSD stated "Unmountable: Unsupported or no file system"
I tired to Mount the SSD using Unassigned Devices but gives me an error "Device '/dev/sdf' failed to mount. Check the syslog for details."
Below is what it generated in the syslog.
I would really like to mount the drive and copy the data over to my array if possible. I also included my diagnostics file.
