GlusterFS is an open-source scalable distributed filesystem that is able to grow to petabytes and beyond in size. More information can be found on Gluster's homepage. This driver enables use of GlusterFS in a similar fashion as the NFS driver. It supports basic volume operations, and like NFS, does not support snapshot/clone. You must use a Linux kernel of version 3.4 or greater (or version 2.6.32 or greater in RHEL/CentOS 6.3+) when working with Gluster-based volumes. See Bug 1177103 for more information. To use Cinder with GlusterFS, first set the volume_driver in cinder.conf: volume_driver=cinder.volume.drivers.glusterfs.GlusterfsDriver The following table contains the configuration options supported by the GlusterFS driver.
