Topic

Updated glusterfs, gluster-afr, gluster-dht, distribution, build,
gluster-nfs, gluster-quota, gluster-smb, gluster-snapshot, gluster-swift,
glusterfs-geo-replication, glusterfs-rdma, and glusterfs-server packages
that fix numerous bugs and add various enhancements are now available
for Red Hat Storage 3.0.

Description

Red Hat Storage is software-only, scale-out storage that provides flexible
and affordable unstructured data storage for an enterprise. GlusterFS, a
key building block of Red Hat Storage, is based on a stackable user-space
design and can deliver exceptional performance for diverse workloads.
GlusterFS aggregates various storage servers over network interconnections
into one large, parallel network file system.

This update fixes numerous bugs and adds various enhancements in RDMA,
SMB, Snapshot, Swift, NFS, Quota, and Geo-replication. Space precludes
documenting all of these changes in this advisory. Users are
directed to the Red Hat Storage 3 Technical Notes, linked to in
the References section, for information on the most significant
of these changes.

This advisory adds the following enhancements:

• With this advisory, User Serviceability Snapshot is out of technology

preview and is supported. You can now view and retrieve snapshots
using CIFS for a Windows client. A new volume set option
'features.show-snapshot-directory' is added to make the '.snaps' directory
explicitly visible at the root of the share. (BZ#1094830)

• With this advisory, Remote Direct Memory Access (RDMA) support for

communication between GlusterFS bricks and clients is out of technology
preview and is supported. It fixes bugs and provides options to configure
RDMA support for the new and existing volumes. (BZ#852276)

• Red Hat Storage Object Store has been rebased to Red Hat OpenStack Icehouse.

This feature allows you to schedule deletion of objects which are stored
in the Red Hat Storage volume. You can use the Object expiration feature
to specify a lifetime for objects in the volume. When the lifetime of
an object expires, it automatically stops serving that object at the
specified time and shortly thereafter removes the object from the
Red Hat Storage volume. (BZ#1180463)

• A new command, 'gstatus' provides an easy-to-use, high-level view of the

health of a trusted storage pool with a single command. It gathers
information by executing the GlusterFS commands, to gather information
about the statuses of the Red Hat Storage nodes, volumes, and bricks.
The gstatus command is under technology preview. (BZ#1171546)

All users of Red Hat Storage are advised to install these updated packages.
