On FreeNAS 11.3. Lately on the last two weekly scrub days one of my drives (the same one both times) has been getting removed from the pool with the error message "state is DEGRADED: One or more devices has been removed by the administrator. Sufficient replicas exist for the pool to continue functioning in a degraded state."
The drive has been showing some S.M.A.R.T. errors during long tests so I have a replacement ordered but if I reboot the server the pool simply shows as healthy again, albeit with 13 checksum errors on that drive. Is the drive still usable or should I just replace it now? Is FreeNAS removing the drive because of the checksum errors or is it drive somehow shutting down during the scrub process?
