I've got my first LVM-based system to be backed up and I'm running into
permission problems. The client system is Fedora Core 4. I've
installed amanda there by 'yum install'ing the amanda and amanda-client
packages. I've enabled amanda in xinetd and reloaded xinetd. I want to
back up just one directory (so using tar) so I add that to my disklist.
The amanda xinetd setup on the client is set to use the 'disk' group.
Here's my debugging so far...
On the server....
---------------------------
$ amcheck -c CIS client
Amanda Backup Client Hosts Check
--------------------------------
ERROR: client.cis.uab.edu: [could not access /var/lib/pgsql/backups
(/var/lib/pgsql/backups): Permission denied]
Client check: 1 host checked in 0.021 seconds, 1 problem found
When using tar, amanda still must have access to the top level
directory. tar itself is run with root priviledges, but amandad,
which does some checks, is not.
Some directory in the path /var/lib/pgsql/backups has no -x permission
for amanda.
On possibility is to make sure the directory has -x on the group,
and make amanda part of that group. E.g. if the permission of
the directory /var/lib/pgsql is:
drwxr-x--- 2 pgsql pgsql 512 Sep 8 11:15 .
then just add amanda tot the pgsql group (in /etc/group).
service amanda
{
socket_type = dgram
protocol = udp
wait = yes
user = amanda
group = disk
Add this line, and reload xinetd:
groups = yes
This is needed to get the additional "pgsql" group permissions too.
server = /usr/lib/amanda/amandad
disable = no
}
# ls -l /dev/mapper/VolGroup00-LogVol00
brw-rw---- 1 root disk 253, 0 Aug 21 11:03 /dev/mapper/VolGroup00-LogVol00
When using tar, amanda does not access this device. Only when using
dump, this device is needed.
