Hello All,
I'm having a bit of a problem in getting Amanda to work.. specifically it's
failing when estimating the dump sizes when amdump is run. The configuration
is, machine "backup" RH Linux 2.4.20-30.9 Amanda server with an HP-DAT
drive, this machine is not a client. The client is machine "augustus", same
spec as "backup" but is configured as a client.
amcheck runs fine on backup:
Amanda Tape Server Host Check

NOTE: skipping tape-writable test

Amanda Backup Client Hosts Check

(brought to you by Amanda 2.4.4p2)
My disklist entry for this test is:
augustus.XXXX.com /etc nocomp-test
amdump fails with the following error taken from
/tmp/amanda/sendsize....debug on "augustus".

Now, if I run that command line as the amanda user, it succeds:
[amanda@augustus amanda]$ /sbin/dump 0Ssf 1048576 - /etc
DUMP: Added inode 8 to exclude list (journal inode)
DUMP: Added inode 7 to exclude list (resize inode)
18119680
18mb or so.. however the total disk size of /dev/md1 is much larger than
this. I've had a look through the know issues and can't see a problem with
the directory sitting on a disk this size.
Many thanks for people looking at this.. I can't see what's wrong with it,
though there is clearly an issue with it.

The amanda user is a member of the disk group:
[amanda@augustus amanda]$ groups
backup disk
The ownership of /dev/md1 is:
[root@augustus root]# ls -l /dev/md1
brw-rw---- 1 root disk 9, 1 Jan 30 2003 /dev/md1
and it's constituent disks are:
[root@augustus root]# ls -l /dev/hde3
brw-rw---- 1 root disk 33, 3 Jan 30 2003 /dev/hde3
[root@augustus root]# ls -l /dev/hdg3
brw-rw---- 1 root disk 34, 3 Jan 30 2003 /dev/hdg3
The output of amdump is:
These dumps were to tape DailySet1-000.
The next tape Amanda expects to use is: a new tape.
