Gluster
● GlusterFS is a general purpose scale-out distributed file-
system supporting thousands of clients
● Aggregates storage exports over network interconnect to
provide a single unified namespace
● File-system
completely in
userspace, runs on
commodity
hardware
● Layered on disk file
systems that
support extended
attributes
02/09/15 6GlusterFS Meetup
oVirt Gluster Integration
● Introduced in oVirt 3.1
● Supports Three ApplicationMode configuration
– 1 → Virtualization only
– 2 → Gluster only
– 255 → Virtualization + Gluster (default)
● Enable Gluster at cluster level
● New entities (Volumes, Bricks, Volume Options)
● VDSM verbs for gluster management
● vdsm-gluster plug-in
02/09/15 7GlusterFS Meetup
Features supported in Ovirt
● Cluster Management
● Create Gluster Cluster
● Add / Remove Storage Servers
● Delete Cluster
● Volume Management
● Create / Remove Volume
● Start / Stop Volume
● Add / Remove (with migration) bricks
● Re-balancing Volume
● Profiling
● Managing hooks

02/09/15 8GlusterFS Meetup
Managing Gluster in oVirt 1/2
● Gluster Service support
is located in the Cluster
properties
● Deploy Hosts with
GlusterFS Server
support
● Enable Bricks and
Volume Management
from oVirt WebAdmin
and REST-API
02/09/15 9GlusterFS Meetup
Managing Gluster in oVirt 2/2
● It is possible to create and manage Gluster Volumes
from WebAdmin and using the REST-API
● Volume Profiling
● Volume Capacity Monitoring
● Re-balancing Volume
02/09/15 10GlusterFS Meetup
Demo
02/09/15 11GlusterFS Meetup
Upcoming Features
in oVirt 3.6
02/09/15 12GlusterFS Meetup
Disk Management
● Identify available disks and storage devices
● Create new bricks by creating new Logical Volumes (Thin
LVs)
● Format the logical volume with the XFS file-system and
manage fstab entries
http://www.ovirt.org/Features/GlusterHostDiskManagement
02/09/15 13GlusterFS Meetup
Gluster Snapshot
● Supports Volume Snapshot related operations
● Snapshot configurations at Volume level as well as
Cluster level
● Supports Snapshot scheduling to take repeated
snapshots based on the time interval
02/09/15 14GlusterFS Meetup
Geo Replication
● Enables creation and maintenance of Geo-
Replication sessions across clusters
http://www.ovirt.org/Features/Gluster_Geo_Replication
02/09/15 15GlusterFS Meetup
Storage Network Selection
● Currently, Gluster nodes
use the same network for
both Management and
Gluster traffic (possibly
causing traffic chokes)
● The proposed solution is
to separate out the
GlusterFS traffic and
management traffic
VMsandStorageEngine Direct-attached storage (SAS/SATA)
