I have a newbie question. I have been getting errors on reboot with my software raid 5 (i use 4x2 TB drives). I created it with MDADM, it takes 6 to 8 hours to set up the 4th drive with parity.
When I shutdown, i see errors that drives have failed (just before shutdown) from mdadm. Then after reboot, my raid 5 is in auto/read-only and says it needs to rebuild again.
I’ve been googling around but I have not been successful in finding a solution so far. Is there a safe way to shutdown the raid 5 I guess, before the machines shuts down or reboots?
Any tips, links or info would be very helpful. Thanks everyone!
