Well, here we go again. For some reason, after the last update, I could not get the replication service to restart on the other 12TB pool. All the usual tricks didn’t work. I ended up having to delete and recreate the RockNASBU pool to get it going again.
All this happened after a power glitch that occurred previous to the last update. I think it is time to hook up a UPS and see if that helps.
