Do you mean autofs would not mount the drive after the crash? As in, the
ls command hung when you tried to list the drive's root directory? If
so, did you look at dmesg following the crash? Neither Bacula nor
vchanger do anything that should affect autofs. They are just
reading/writing files.
Also, did the vchanger initmag command give any messages? It looks like
there are only 4 volume files listed after the crash, but the
slots_per_magazine=12 in the vchanger config should have caused initmag
to create 12 (empty) volume files. Did the 'label barcodes' command in
bconsole work as expected?
I suggest you run e2fsck on the drives, then erase the files on the
drive and in /var/lib/bacula/vchanger and re-run the initmag. Before
using with Bacula, check that listmags works as expected. Then perform a
load and unload manually with vchanger and confirm that also works. If
not, then it may be a permissions issue. The root directory of the
drives and the /var/lib/bacula/vchanger directory must have rwx for the
user:group that bacula-sd runs as.
