I just installed Bacula 9.44 Community and am backing up to a ZFS drive. It
works fine with a regular setup.
If I switch to using the Aligned device type then I get the error below. I
switched back to a regular setup but would like to use deduplication since
it would save me a lot of space because my full backups are 5 TB but most
of the files are not changing between ful backups.

Device "Aligned-Disk" requested by DIR could not be opened or does not
exist.
11-Jul 09:29 jw-sd JobId 13: Error: [SE0003] Lookup of symbol
"BaculaSDdriver" in driver Aligned-Disk for device /opt/bacula/plugins/
bacula-sd-aligned-driver-9.4.4.so failed: ERR=/opt/bacula/plugins/
bacula-sd-aligned-driver-9.4.4.so: undefined symbol: BaculaSDdriver
---------------------------------------------------------------------------------------------------------------------------
My OS is latest Centos 7. I installed Bacula from the Bacula 9.4.4 repo. It
appeared to install the plugin successfuly. Yum shows it as installed. It
seems like Bacula is finding it since it lists the correct path to the
plugin.
I set up Bacula for deduplication using the directions at
http://www.bacula.lat/block-level-deduplication-with-aligned-volumes-tutorial-bacula-7-9-9-0-and-above/?lang=en.
See my device entry quoted further down below.
I ran a few programs on the plugin to show the symbols but they do not show
BaculaSDdriver in the plugin. I do not really know what I am doing with
that. I also looked at the plugin itself for text with this value but did
not see it.
I saw a post (wsee below) where someone has the same problem with 9.4.3. I
could not figure out how to reply to that post since I just joined the
bacula-users list today.
Any idea how to fix this problem or if it is a bug?
Thanks,
Joe
