There is an important performance bug fix specific to NetBSD here,
which disable gfid2path by default. This features causes a huge
amount of different extended attributes to be created, and the
NetBSD implementation does not scale well with it.
In order to recover a server after the feature is disabled, stop
glusterfs daemones, disable extended attributes using extattrctl,
remove ${BRICK_ROOT}/.attribute/system/trusted.gfid2path.*
re-enable extended attributes and restart glusterfs.
From http://blog.gluster.org/2016/06/glusterfs-3-8-released/
Gluster.org announces the release of 3.8 on June 14, 2016, marking
a decade of active development.
The 3.8 release focuses on:
- containers with inclusion of Heketi
- hyperconvergence
- ecosystem integration
- protocol improvements with NFS Ganesha
Contributed features are marked with the supporting organizations.
Automatic conflict resolution, self-healing improvements (Facebook)
Synchronous Replication receives a major boost with features
contributed from Facebook. Multi-threaded self-healing makes
self-heal perform at a faster rate than before. Automatic
Conflict resolution ensures that conflicts due to network
partitions are handled without the need for administrative
intervention
NFSv4.1 (Ganesha) - protocol
Gluster's native NFSv3 server is disabled by default with this
release. Gluster's integration with NFS Ganesha provides NFS
v3, v4 and v4.1 accesses to data stored in Gluster volume.
BareOS - backup / data protection
Gluster 3.8 is ready for integration with BareOS 16.2. BareOS
16.2 leverages glusterfind for intelligently backing up objects
stored in a Gluster volume.
"Next generation" tiering and sharding - VM images
Sharding is now stable for VM image storage. Geo-replication
has been enhanced to integrate with sharding for offsite
backup/disaster recovery of VM images. Self-healing and data
tiering with sharding makes it an excellent candidate for
hyperconverged virtual machine image storage.
block device & iSCSI with LIO - containers
File backed block devices are usable from Gluster through iSCSI.
This release of Gluster integrates with tcmu-runner
[https://github.com/agrover/tcmu-runner] to access block devices
natively through libgfapi.
Heketi - containers, dynamic provisioning
Heketi provides the ability to dynamically provision Gluster
volumes without administrative intervention. Heketi can manage
multiple Gluster clusters and will be the cornerstone for
integration with Container and Storage as a Service management
ecosystems.
glusterfs-coreutils (Facebook) - containers
Native coreutils for Gluster developed by Facebook that uses
libgfapi to interact with gluster volumes. Useful for systems
and containers that do not have FUSE.

The release of 3.8 also marks the end of life for GlusterFS 3.5,
there will no further updates for this version.
