Eric and Frank, thank you very much for your detailed analysis of my problem.
I just noticed on the most recent amstatus I ran that centernet:sda5 completed,
and admin:sda3 is now dumping to tape. I've pasted in the most recent amstatus
to the end of this note. I guess the reason that it says just "dumping to tape"
rather than centernet's "dumping 1332992k ( 73.56%) (2:02:34)" is that admin
is the tapehost itself.
The holding disks on the tapehost are large, I thought:
amanda@admin:~ > df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 7.6G 5.2G 2.0G 72% /
/dev/sda1 22M 3.4M 17M 16% /boot
/dev/sdb1 8.3G 753M 7.1G 10% /var/amanda #This is hd1 (holding
disk 1)
/dev/sdc1 33G 4.9G 26G 16% /dumps2 # and this is hd2
shmfs 1009M 0 1009M 0% /dev/shm
amanda@admin:~ >
They don't seem to be in use at this late stage of this backup:
amanda@admin:/dumps2/amanda > du -sxh . /var/amanda/
8.0k .
12k /var/amanda
amanda@admin:/dumps2/amanda >
Centernet is a low-volume web server, primarily. Even while running the backup,
the load was less than 2. It's a 600MHz dual Pentium Dell PowerEdge 2450 with
256MB, 100MHz RAM. The tapehost, in contrast, right now has a load of almost 4:
amanda@admin:/dumps2/amanda > uptime
4:24pm up 1 day, 23:30, 1 user, load average: 3.77, 3.71, 3.57
amanda@admin:/dumps2/amanda >
There's no firewall between centernet and the tapehost, admin. Both are inside
our firewall. The network is switched 100Mbps Ethernet.
Here's a ps list of the amanda jobs currently running on the tapehost:

I'll send in the daily report as soon as I receive it. Normally, I would have
interrupted amanda around 2:00pm by just killing all the amanda jobs on admin
and running amcleanup. Then, I would put the next tape in and run amflush. This
would complete before I needed to put the next tape in for the nightly run and
go home. Tonight, I'll just let it run out. In addition, there's a thunderstorm
rolling through Baltimore right now and all the lights are flickering. All the
servers are on a UPS, but my workstation isn't.
The partitions on admin like "admin://db/c$" are actually Samba shares from an
NT host.
Thanks, again, for all your suggestions. I won't make any changes right now,
until you've had a chance to look at the daily report. I appreciate all your
help.
It still hasn't ended and it's 5:03 and I'm hungry and tired, so I'm going
home. I'll talk with you all again tomorrow.
