[Bug 1060422] [NEW] nova-volume volume creation fails, tgt config not loaded

[Adam Gandelman]

Public bug reported:


Commit @ https://review.openstack.org/#/c/13633/ removes the explicit specification of volume config files to tgt-admin, and instead relies in tgt's configuration being set to find those config files in the appropriate place (nova's volumes directory).  We've been shipping a file in /etc/tgt/nova_tgt to specify this directory and import all configs there, but it appears that it is not actually picking them up.  With the --conf flag now removed, volume creation fails with tracebacks such as:
