Problem dumping / filesystem (read error)

Post by Bernard PERR » Sat, 15 Feb 1997 04:00:00


I am using 'dump' to backup all my filesystems regulary.
Since two days, I don't understand why, dump crashe when dumping my root (/)
filesystem with a message :
 DUMP: dumping (Pass III) [directories]
 DUMP: read error from /dev/sda2: Bad address [block 3523]: count=3608576

Fsck (1.06) don't detect anything !

What to do ? Any idea about the problem ? A solution ?

Thanks in advance.


1. ufsdump 0f /dir/filesystem.dump /filesystem requires second tape?

When I do
ufsdump 0f /dir/filesystem.dump /filesystem
on a large filesystem, it tells me that I need a second tape.

Then I use
ufsdump 0cf /dir/filesystem.dump /filesystem
and it seems to work. But I think it still has a limit there.
Is there a option to tell ufsdump it is a filesystem, not a tape,
so that there would not be a second tape? Thanks.
