GlusterFS 3.8.10 is available

The 10th update for GlusterFS 3.8 is available for users of the 3.8 Long-Term-Maintenance version. Packages for this minor update are in many of the repositories for different distributions already. It is recommended to update any 3.8 installation to this latest release.

Release notes for Gluster 3.8.10

This is a bugfix release. The Release Notes for 3.8.0, 3.8.1, 3.8.2, 3.8.3, 3.8.4, 3.8.5, 3.8.6, 3.8.7, 3.8.8 and 3.8.9 contain a listing of all the new features that were added and bugs fixed in the GlusterFS 3.8 stable release.

Improved configuration with additional 'virt' options

This release includes 5 more options to group virt (for VM workloads) for optimal performance.
Updating to the glusterfs version containing this patch won't automatically set these newer options on already existing volumes that have group virt configured. The changes take effect only when post-upgrade
# gluster volume-set <VOL> group virt
is performed.
For already existing volumes the users may execute the following five commands, if not already set:
# gluster volume set <VOL> performance.low-prio-threads 32
# gluster volume set <VOL> cluster.locking-scheme granular
# gluster volume set <VOL> features.shard on
# gluster volume set <VOL> cluster.shd-max-threads 8
# gluster volume set <VOL> cluster.shd-wait-qlength 10000
# gluster volume set <VOL> user.cifs off
It is most likely that features.shard would already have been set on the volume even before the upgrade, in which case the third volume set command above may be skipped.
