Still doesn't work. I've split the /home partition into several pieces as
recommended in an earlier message (my disklist entries are included at
the end). Since I havent' received the usual email report from amanda
(why??), I went to /tmp/amanda to see the logs. It looks like sendsize
is run with non-root privileges hence it cannot stat/read individual
home directories (quite normal as they are restricted to the owner). This
is what I found:
sendsize: debug 1 pid 5628 ruid 103 euid 103: start at Thu Nov 13 23:59:01
2003
...

...
sendsize[5630]: estimate time for /etc level 0: 0.897
sendsize[5630]: estimate size for /etc level 0: 3650 KB
estimate for level 0 for /etc succeeded fine in less then a second.
...
sendsize[5630]: estimate time for /etc level 1: 0.050
sendsize[5630]: estimate size for /etc level 1: 120 KB
the same for level 1 even faster.
Next amanda tries /home_h0:
...
sendsize[5633]: time 1.051: calculating for amname '/home_h0', dirname
'/home', spindle -1
sendsize[5633]: time 1.051: getting size via gnutar for /home_h0 level 0
The runtar is the program that needs to be suid-root. Verify this
please. /home isn't an nfs-mount by accident? On a normal nfs-mounted
directory, root on the cleint becomes "nobody" on the server.
You have to specify special mount options on the nfs-server to get
root==root. See the "no_root_squash" option in the exports file.
sendsize[5633]: time 1.139: spawning /usr/local/libexec/runtar in pipeline

Try to execute the above command line interactively, as root.
Does that work?

....... (similar messages repeated) .....
Do these directories/files actually exist? Or are they shortlived,
and between the time amanda expanded the "./h[0]*" in the file
/tmp/amanda/sendsize._home__h0.20031113235902.include and the time
that gtar was started. It's only a second (1.172 sec to be precise),
but these days computers can get really fast.
Also the message is "No such file or directory" instead of "Permission
denied". Usually I believe those error messages in Unix.
...
My disklist:
rozi.cab.u-szeged.hu /etc root-tar
rozi.cab.u-szeged.hu /home_h0 /home { # h0*
user-tar
include "./h[0]*"
}
...
rozi.cab.u-szeged.hu /home_rest /home { # the rest
user-tar
exclude "./h[0-9]*"
}
