First, remove the RemovableMedia=yes line from the Vchanger-drive Device
in bacula-sd.conf. That causes Bacula to search for any file on
ArchiveDevice that may be appendable and usable for the job. With
vchanger, a specific file is mapped to a slot, so the search is not wanted.
Remember that vchanger will be run as the same uid:gid that bacula-sd
runs as. So /etc/bacula/vchanger must be executable by that user.
/etc/bacula/vchanger.conf must be readable, the vchanger work_dir and
all magazine filesystems must be writable by that user. Check filesystem
permissions. Also, if you use seLinux, ensure that /etc/bacula/vchanger
has needed permissions. Set logfile= in vchanger.conf to a file writable
by the uid:gid bacula-sd runs as and log_level=7 to get detailed logging
from vchanger that might point out the problem.
My guess is permissions. As root, use the -u and -g switches to run
vchanger manually and force the same uid:gid that bacula-sd runs as. A
simple su bacula may not run with the same permissions.
