Last Sunday my NAS540 again started do recompute RAID 5 parity. As I had to switch it of, I lost connection and it took some time until reconnect was possible again.
Why does the system have to resync RAID 5 parity?
Thanks!

I think one of your disks is dropped from the array from time to time. I didn't know it would re-add that disk without command.

Strange. Having a hot spare I'd expect the system to switch to the hot spare.
I am not sure, but it may be that the problem occurs when I unplug the power supply for more that two days. I could test it, but I don't like the trouble when my assumption ist true.
I'll wait to see whether it happens again.
