You can now access gluster -volumes directly from qemu and samba without having to come through a -regular filesystem mount point. - -### Quorum enforcement from Trusted Storage Pool - -Quorum can now be enforced from the Trusted Storage Pool. Connectivity -information present in glusterd is used to determine quorum. Server Side quorum - can be enabled by: - -*\#gluster volume set <volname\> cluster.server-quorum-type server* - -*\#gluster volume set <volname\> cluster.server-quorum-ratio <percentage\>* - -More details about this feature can be found [here] -(http://www.gluster.org/community/documentation/index.php/Features/Server-quorum). - - -### Improvements for Virtual Machine Image Storage - -A number of improvements have been performed to let Gluster volumes provide -storage for Virtual Machine Images. Some of them include: - -- qemu - libgfapi integration. -- Causal ordering in write-behind translator. -- Tunables for a gluster volume in group-virt.example. - -The above result in significant improvements in performance for VM hosting. - - -### Synchronous Replication Improvements - -GlusterFS 3.4 features significant improvements in performance for the -replication (AFR) translator. This is in addition to bug fixes for volumes that -used replica 3. - - -### Open Cluster Framework compliant Resource Agents - -Resource Agents (RA) plug glusterd into Open Cluster Framework -(OCF) compliant cluster resource managers, like Pacemaker. - -The glusterd RA manages the glusterd daemon like any upstart or systemd job -would, except that Pacemaker can do it in a cluster-aware fashion. - -The volume RA starts a volume and monitors individual brick daemons in a -cluster aware fashion, recovering bricks when their processes fail. - - -### POSIX ACL support over NFSv3 - -setfacl and getfacl commands now can be used on a nfs mount that exports a -gluster volume to set or read posix ACLs. - -### 3.3.x compatibility - -The new op-version infrastructure provides compatibility with 3.3.x release of -GlusterFS. 3.3.x clients can talk to 3.4.x servers and the vice-versa is also -possible. - -If a volume option that corresponds to 3.4 is enabled, then 3.3 clients cannot -mount the volume. - -### Packaging changes - -New RPMs for libgfapi and OCF RA are present with 3.4.0. - -### Brick port changes - -Brick ports will now listen from 49152 onwards (instead of 24009 onwards as with -previous releases). The brick port assignment scheme is now compliant with IANA -guidelines. - -### Experimental Features - -The following features are experimental with this release: - -- RDMA-connection manager (RDMA-CM). -- Block Device translator. -- support for NUFA translator. - -## Minor Improvements: - -- The Ext4 file system change which affected readdir workloads for Gluster - volumes has been addressed. - -- More options for selecting read-child with afr available now. - -- Custom layouts possible with distribute translator. - -- No 32-aux-gid limit - -- SSL support for socket connections. - -- Known issues with replica count greater than 2 addressed. - -- quick-read and md-cache translators have been refactored. - -- open-behind translator introduced. - -- Ability to avoid glusterfs bind to reserved ports. - -- statedumps are now created in /var/run/gluster instead of /tmp by default. - -- UFO Rebased to Openstack Swift 1.8.0 (Grizzly). - -Note that UFO will be renamed G4S (Gluster For Swift) and decoupled from -GlusterFS in the next release. The UFO source in the GlusterFS ufo subdirectory -is deprecated following this release. -The G4S source is now in the separate git repository [here] -(ssh://git.gluster.com/gluster-swift.git). - -- glusterfs.spec.in mirrors the Fedora glusterfs.spec (delta UFO packages until - G4S packages land in Fedora.) - -- Gluster NFS server now listens by default on port 2049. This allows auto - negotiation with NFS clients. - -- timestamps are now all in UTC - -### Known Issues: - -- The following configuration changes are necessary for qemu and samba - integration with libgfapi to work seamlessly: - - 1) gluster volume set <volname> server.allow-insecure on - - 2) Edit /etc/glusterfs/glusterd.vol to contain this line: - option rpc-auth-allow-insecure on - - Post 2), restarting glusterd would be necessary. - -- RDMA connection manager needs IPoIB for connection establishment. More - details can be found [here] -(https://github.com/gluster/glusterfs/blob/master/doc/features/rdma-cm-in-3.4.0.txt). - -- When NUFA is enabled, client mounts fail outside the trusted storage pool. - -- Quota enforcement does not work correct with NFS access. - -- replace-brick operation does not work fine in all cases in this release. -More details can be found [here] -(https://bugzilla.redhat.com/show_bug.cgi?id=996047) - -- For Block Device translator based volumes open-behind translator at the -client side needs to be disabled. - -- More information on this can be found in this mailing list - [post](http://www.gluster.org/pipermail/gluster-users/2013-July/036750.html) - A freshly installed peer cannot be probed into a freshly upgraded cluster. - This is a limitation brought about by the introduction of op-versions. - There are two ways to workaround this issue, - * enable any new feature (for eg. open-behind) on a volume in the cluster, - and then perform the probe. - Or, if you don't want to enable any new features - * delete the 'operating-version' line from /var/lib/glusterd/glusterd.info - on the newly installed peer and restart glusterd on the peer. - If the file doesn't exist (because of lazy uuid generation), try to probe - the peer from the cluster (which will fail) to get the file created. |
