Hi folks--
I have an amd64 machine with two drives. 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.
Chris
