I've got my system set up on ad8, and I'm building a RAID0 array using gvinum that will span ad8 and ad10. So for now, I have partitions on ad8 plus a set of volumes on ad10 that I want to move all my data to. Today I was doing a test move of all the data, using dump | restore like this: # dump -0aL -f - /var | ( cd /mnt/var && restore -rf - ) I got about a dozen messages like this: DUMP: read error from /dev/ad8s1d: Bad address: [block 10992192]: count=5120 What is causing this message, and is it a cause for alarm? Here's my bsdlabel for ad8s1: # /dev/ad8s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 1048576 0 4.2BSD 2048 16384 8 b: 4123872 1048576 swap c: 488279547 0 unused 0 0 # "raw" part, don't edit d: 104857600 5172448 4.2BSD 2048 16384 28528 e: 2097152 110030048 4.2BSD 2048 16384 28528 f: 376152347 112127200 4.2BSD 2048 16384 28528 Thanks in advance for any help.
