Hi Ryan,

all my Servers are on Ubuntu 14.04 64 Bit.
Bacula version is 5.2.6+dfsg-9.1ubuntu3
Using Gluster 3.5.5 packages from: https://launchpad.net/~gluster
4 Gluster nodes. All volumes are distributed-replicate.
Mounted via fuse or nfs.

Only "problem" i have is poor small file performance while backuping.
Workaround is to mount an image via libgfapi in my vms. This works
faster as fuse / nfs mount.


Regards
André
