exclude list problems (PEBKAC?)
I've checked the docs/FAQ/google/archives and I must be missing
something really simple. :\
I have an amanda client that I'm backing having problems backing up.
We're using tar for /usr on this client:
SNIP disklist snippet
client /usr no-mirror-tar
SNIP
Here's the def for no-mirror-tar:
SNIP amanda.conf snippet
define dumptype no-mirror-tar {
global
program GNUTAR
compress client fast
comment usr partitions dumped with tar
exclude list .amanda-exclude.gtar
priority medium
}
SNIP
The global config only has a comment and 'index yes.'
The exclude list (on the client) has this:
SNIP
$ cat /usr/.amanda-exclude.gtar
./local/mirror
./local/www/logs
SNIP
The runtar.debug looks like this:
SNIP
gtar: version 2.4.2
running: /usr/local/bin/tar: gtar --create --directory /usr
--listed-incremental /usr/local/var/amanda/gnutar-lists/client_usr_0.new
--sparse --one-file-system --ignore-failed-read --totals --file -
--exclude-from /usr/.amanda-exclude.gtar .
SNIP
And the backup of this partition errors out with this:
SNIP
/-- client /usr lev 0 FAILED [/usr/local/bin/tar returned 2]
sendbackup: start [client:/usr level 0]
sendbackup: info BACKUP=/usr/local/bin/tar
sendbackup: info RECOVER_CMD=/usr/local/bin/gzip -dc |/usr/local/bin/tar
-f... -
sendbackup: info COMPRESS_SUFFIX=.gz
sendbackup: info end
? gtar: Cannot add file ./local/mirror/pub/redhat/i386
.
.
.
| Total bytes written: 8484853760
? gtar: Error exit delayed from previous errors
sendbackup: error [/usr/local/bin/tar returned 2]
\
SNIP
There's also a 'file changed as we read it' error, but all of these
errors come from ./local (/usr/local) in places that are excluded (see
above).
Suggestions?
Thanks,
Mike

Your config looks correct to me. What does '/usr/local/bin/tar --version'
show? Can your backup user read the exclude file?

You can compile amanda to consider this exit message and status as normal by placing in config.h a line like #define IGNORE_TAR_ERRORS 1 -- Jon H.

What burns me a bit is that the usual tar --version, doesn't eject the minor number, so thery are all 1.13's. One must forcibly remove any tar thats there, and reinstall a known good one to be sure. -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.17% setiathome rank, not too shabby for a WV hillbilly

Hmm, on my Debian linux server here I get: # /usr/local/bin/tar --version tar (GNU tar) 1.13.19 and on one of my Solaris boxes: # /usr/local/bin/tar --version tar (GNU tar) 1.13.25 Both were compiled from source, but even on a RedHat 7.2 box I see: #/bin/tar --version tar (GNU tar) 1.13.19 Maybe they started including the minor number in the version string somewhere along the line.
