Dump for Linux

Ragni Singh — Fri, 27 Jun 2003 16:51:19 GMT

Hi all,

I'm trying to run this command ..

dump -0u -f /dev/st0 / to backup everything from /down but its not working. How do I specify using dump to do everything from root down. Any help is greatly appreciated and points will be assigned.

# dump -0u -f /dev/st0 /

Thats what I'm doing. Here is the filesystem that I have created using lvm in Linux.

DUMP: Dumping /dev/vg00/lvol1 (/) to /dev/st0
DUMP: Added inode 8 to exclude list (journal inode)
DUMP: Added inode 7 to exclude list (resize inode)
DUMP: Label: none

This only seems to dump thinsg in lvol1 and I was undeer the impressing that specifying a / will in fact dump everything from / down.

try:
dump 0uaf /dev/st0 /down

or:

dump 0unf - /down | gzip -c | dd of=/dev/st0 obs=512

Thank you but none of these works.

try to carry out the following 2 tests and see whether they succeed:
1.
# dump -0u -f /dev/st0 /tmp
2.
# dump -0u -f /var/tmp/boot.dmp

Which fstype dou you use? etx2, ext3, xfs, ...?
Can you post the result of mount command, and errors you are getting?
