Dear folks,
After running FreeBSD for a couple of years in what was basically a
sandbox, I recently put several machines into production and am now
enjoying all of the privileges and problems that go along with such a move!
I've checked the archives but haven't found anything that sounds quite like
this. I am attempting to get backups working on a fileserver running Samba
on 4.3-Release with a custom kernel. This is a dual-PPro machine using
vinum to stripe data over 7 physical disks. Full dmesg is at the end of
this message.
When I try to do a dump, it seems to run fine for a short period and then
fails. I initially thought it may have been dump choking on the striped
vinum volume for some reason, but it also fails on /, which is not part of
the concatenated plex and resides entirely on a single disk. I have tried
various command line arguments in an attempt to find something that works,
but haven't had any luck. I have tried:
dump -0af /dev/sa0 /mnt/mainvol
dump -0a /dev/da0s1a
dump -0a -f - /dev/da0s1a | gzip -9v > /dev/sa0
and probably a few other variations over the past few days, all with
similar results. This is what I see on the terminal when trying 'dump -0a
/dev/vinum/mainvol'

When I attempted to pipe it through gzip, it ran for a time and then
terminated with a broken pipe, followed by more errors like the above.
I have tried 3 different tapes with similar results. Am I looking at some
kind of problem with the tape drive? Have I failed to do something to
prepare the tapes for use by dump? Is it an Idiot Operator error? (The most
likely cause!)
Any advice would be welcome. Thank you!
Matt
