Hello all,

I recently upgraded from 2.4.3 to 2.5.1p3 and things have mostly been
working correctly except for a few rough edges.  To complicate matters,
we also upgraded from an AIT drive to an LTO drive.  We're currently
using 100GB tapes, which comfortably fit an entire level 0 dump (about
60GB).

We run bsdtcp auth on all hosts (the main thing driving the update, some
remote sites had mtu issues that would cause big estimates to get
dropped).

We have about 20GB of holding disk space available.

We use a mix of gtar (1.16.1) and dump, all on FreeBSD 4.11.

Going through the logs it looks like I've got a number of problems.

First is the tape size issue:

[devel2]/var/log/amanda # grep FAIL log.20070329.0
FAIL planner b02.foo.com /var/qmail 20070329 0 [dump larger than
available tape space, 2147483647 KB, but cannot incremental dump new
disk] FAIL planner b02.foo.com /var/db/pkg 20070329 0 [dump larger than
available tape space, 2147483647 KB, but cannot incremental dump new
disk]

Hummm, why do I seem to detect the odor of a 2GB file size limit in your
BSD filesystems?  I'd surely think this has been fixed, but I believe
that number is 2GB-1 in decimal notation.

This seems odd since not only do we have more than enough tape space,
but those are very, very small tar backups:

[b02]/var/db/pkg # du -hs
3.8M    .
[b02]/var/qmail # du -hs
1.5M    .

Then we have issues that look like permissions issues, but I can't
reproduce them by hand:

FAIL dumper b02.foo.com / 20070329 0 [err create
/var/db/amanda/index/b02.foo.com/_/20070329_0.gz.tmp: Operation not
permitted]

Selinux?  Or are you perchance running amdump as root?

[devel2]/var/log/amanda # su -m operator -c "touch
/var/db/amanda/index/b02.foo.com/_/20070329_0.gz.tmp"
[devel2]/var/log/amanda # ls -l
/var/db/amanda/index/b02.fo.com/_/20070329_0.gz.tmp
-rw-r--r--  1 operator  wheel  0 Mar 30 20:24
/var/db/amanda/index/b02.foo.com/_/20070329_0.gz.tmp

And then I assume this error is related:

FAIL chunker b02.foo.com / 20070329 0 [cannot read header: got 0
instead of 32768]

And on the client side:

sendbackup: time 1.226:  87:  normal(|):   DUMP: dumping (Pass III)
[directories]
sendbackup: time 1.387:  87:  normal(|):   DUMP: dumping (Pass IV)

sendbackup: time 6426.055: pid 64720 finish time Thu Mar 29 05:19:43
2007

And also some chunker errors that have no corresponding dumper errors:

FAIL chunker h10.foo.com /spool 20070329 0 [cannot read header: got 0
instead of 32768]

On the client:

sendbackup: time 5543.622:  87:  normal(|):   DUMP: 3.63% done, finished
in 37:33
sendbackup: time 5843.560:  87:  normal(|):   DUMP: 3.86% done, finished

sendbackup: time 6358.557: pid 67054 finish time Thu Mar 29 05:20:00
2007

And then at the end of the log I have a number of warnings:

WARNING driver chunker4 pid 18178 exited with signal 1
WARNING driver dumper4 pid 18032 exited with signal 1
WARNING driver dumper3 pid 18031 exited with signal 1
WARNING driver dumper2 pid 18030 exited with signal 1
WARNING driver chunker2 pid 18852 exited with signal 1

Can anyone help me kind of focus on a few root issues here?  I'm having
a really hard time chasing down all these different errors at once.

Thanks,

Charles

First, and it might not be related, amanda is to be built by a normal
user, preferably a user named amanda that you have added, and who has
been made a member of the group disk (or backup, there are others too)
that have enough perms to wander about the system.

Thanks,

Charles

Only the install is to be done as root.

Doing that will eliminate one potential list of perms problems.
