Public bug reported:

VStorage share is mounted by fuse using vstorage-mount utility
(pstorage-mount is symlink). This utility has the option to specify log
file "-l". Currently default log path used by nova-compute is
"/var/lib/pstorage". However when VStorage package is installed it
creates "/var/lib/vstorage" instead. So this needs to be default value
in nova.conf. Non-existent log path results in vstorage-mount fail like:

Command: sudo cinder-rootwrap /etc/nova/rootwrap.conf pstorage-mount -c mycluster -l /var/log/pstorage/nova-mycluster.log.gz -u nova -g root -m 0770 /var/lib/nova/mnt/a0836a988e84c4c0245d1ffa7cee4921
Exit code: 253
Stdout: u''
Stderr: u'19-05-17 16:28:52.719 failed to access directory /var/log/pstorage - No such file or directory\n'
