I got some advice to preform the parity swap procedure in order to upgrade my parity drive and use the old parity for a data-rebuild of a failed drive. I think I started the procedure on 12/20 and it completed 12/21, but when I looked at my Main Array page the Start array button wasn't enabled, but instead looked like it was asking if I wanted to preform a copy operation again...any advice?

Dec 21 17:59:39 UNAS emhttpd: copy: disk3 to disk0 completed

Parity copy completed successfully, and after that's done you can only click on start array to begin the rebuild or it will reset the procedure, did you do anything else?

I didn't do anything else. I was out at the movies watching the new SpiderMan during the time the parity should've finished and I come home and crashed afterwards. Didn't even touch the server.

Maybe having the preclear plugin running interfered with it, not sure, never tried it.

Could be a possibility...say I wait for the PreClear on the other drive finish. If I kick off the parity swap procedure again I sohuldn't lose any data right? Any risk of data loss if I restarted the server?

No, it will just start over.

No, again you'd need to restart the procedure.

Thanks for the info. Shame we still don't know why the swap failed when the log said it completed. At this point the main suspect is having another drive getting precleared at the same time might've caused intereferance...Best of luck to anyone else. I'll redo the parity swap after the other drive is done with its preclear and hope that resolves the issue...
