hi.

i am messing around with amanda tryin to get it working. and
am unsure why i recieve this error message:

Amanda Backup Client Hosts Check
--------------------------------
ERROR: mail-wa2: [can not access /dev/hda7 (hda7): Permission denied]
ERROR: mail-wa2: [can not access /dev/md0 (md0): Permission denied]
Client check: 1 host checked in 0.092 seconds, 2 problems found.

(brought to you by Amanda 2.4.1p1)

my disklist shows:
mail-wa2 md0 always-full
mail-wa2 hda6 comp-root-tar
mail-wa2 hda7 comp-user

i checked the permissions, /dev/md0 and hda7 have the same
permissions as hda6

backup@mail-wa2:~$ ls -l /dev/hda6 /dev/md0 /dev/hda7
brw-rw----    1 root     disk       3,   6 Nov 30 07:22 /dev/hda6
brw-rw----    1 root     disk       3,   7 Nov 30 07:22 /dev/hda7
brw-rw----    1 root     disk       9,   0 Dec 11 21:03 /dev/md0

permissions seem to be ok? :
backup@mail-wa2:~$ id 
uid=34(backup) gid=34(backup) groups=34(backup),6(disk),26(tape)
backup@mail-wa2:~$ /sbin/dump -S /dev/hda6
35379200
backup@mail-wa2:~$ /sbin/dump -S /dev/hda7
270146560
backup@mail-wa2:~$ /sbin/dump -S /dev/md0 
1456024576

can't figure out why it can access /dev/hda6(mounted as /) but
not able to access /dev/hda7(mounted as /usr) or /dev/md0(mounted
as /var/spool)

running debian 2.2r2 on both systems. apt-get'd amanda this
afternoon. this is my first time playing with amanda, if you
need more info lemme know.

thanks

nate
