Near the end of a rather long level 0 dump to a DLT drive today, I got these errors spit at me. /dev/aacd0s2f is a RAID10 config of 4 36Gb drives for a 69,577,710 K-byte file system. It is an active partition storing a postgresql database that is being updated 24x7. Is this just due to the activity on the FS or am I potentially looking at some hardware issues arising? The tape host is running 4.8-RELEASE and the server being dumped is 4.7-RELEASE-p3.
