Hi...
I had the same error today in ubuntu server:
================
$ sudo vchanger -u bacula -g bacula /etc/bacula/disco_usb.conf initmag 1
magazine bay 1 has no magazine mounted
$ sudo vchanger -u bacula -g tape /etc/bacula/disco_usb.conf initmag 1
magazine bay 1 has no magazine mounted
$ sudo vchanger -u bacula -g disk /etc/bacula/disco_usb.conf initmag 1
magazine in bay 1 (/mnt/vchanger/29d9d497-62dd-4903-9054-a3fb9777b79d)
already initialized as magazine 1
================
bacula-dir and bacula-sd are working in "bacula" and "tape" groups
respectively and all folders and files have this groups.
=================
$ find /var/lib/bacula/ /var/log/bacula/ /var/bacula -not -group
bacula -and -not -group tape
/var/log/bacula/
=================
and after check the output of strace
=================
$ sudo strace -s 100 vchanger -u bacula -g bacula
/etc/bacula/disco_usb.conf initmag 1
stat64("/dev/sdc1", {st_mode=S_IFBLK|0660, st_rdev=makedev(8, 33), ...}) = 0
time(NULL) = 1309454624
stat64("/dev/sdc1", {st_mode=S_IFBLK|0660, st_rdev=makedev(8, 33), ...}) = 0
open("/dev/sdc1", O_RDONLY|O_LARGEFILE) = -1 EACCES (Permission denied)
read(4, "", 1024) = 0
close(4)
=================
I found that the problem is that vchanger try to access the device
(/dev/sd*) directly and not the directory/mountpoint configured..
and how the script are running with a group (bacula/tape) that don't
have access do /dev/sd*, the script don't work...
===========
$ ls -ltr /dev/sd*
brw-rw---- 1 root disk 8, 16 2011-06-28 11:16 /dev/sdb
brw-rw---- 1 root disk 8, 0 2011-06-28 11:16 /dev/sda
brw-rw---- 1 root disk 8, 1 2011-06-28 11:16 /dev/sda1
brw-rw---- 1 root disk 8, 17 2011-06-28 11:16 /dev/sdb1
brw-rw---- 1 root disk 8, 21 2011-06-28 11:16 /dev/sdb5
brw-rw---- 1 root disk 8, 18 2011-06-28 11:16 /dev/sdb2
brw-rw---- 1 root disk 8, 32 2011-06-30 12:10 /dev/sdc
brw-rw---- 1 root disk 8, 33 2011-06-30 12:10 /dev/sdc1
===========
solution... mmm .. include bacula in disk group ??
