New features: - Volume Snapshots Distributed lvm thin-pool based snapshots for backing up volumes in a Gluster Trusted Storage Pool. Apart from providing cluster wide co-ordination to trigger a consistent snapshot, several improvements have been performed through the GlusterFS stack to make translators more crash consistent. Snapshotting of volumes is tightly coupled with lvm today but one could also enhance the same framework to integrate with a backend storage technology like btrfs that can perform snapshots. - Erasure Coding Xavier Hernandez from Datalab added support to perform erasure coding of data in a GlusterFS volume across nodes in a Trusted Storage Pool. Erasure Coding requires fewer nodes to provide better redundancy than a n-way replicated volume and can help in reducing the overall deployment cost. We look forward to build on this foundation and deliver more enhancememnts in upcoming releases. - Better SSL support Multiple improvements to SSL support in GlusterFS. The GlusterFS driver in OpenStack Manila that provides certificate based access to tenants relies on these improvements. - Meta translator This translator provides a /proc like view for examining internal state of translators on the client stack of a GlusterFS volume and certainly looks like an interface that I would be heavily consuming for introspection of GlusterFS. - Automatic File Replication (AFR) v2 A significant re-factor of the synchronous replication translator, provides granular entry self-healing and reduced resource consumption with entry self-heals. - NetBSD, OSX and FreeBSD ports Lot of fixes on the portability front. The NetBSD port passes most regression tests as of 3.6.0. At this point, none of these ports are ready to be deployed in production. However, with dedicated maintainers for each of these ports, we expect to reach production readiness on these platforms in a future release.

*** GlusterFS clients ***
|
|
This is required in /etc/sysctl.conf in order to avoid hangs on I/O operations
|
|
kern.sbmax=4194304

In order to use mount -t glusterfs, please install this link
|
|
ln -s ${PREFIX}/sbin/mount_glusterfs /sbin/mount_glusterfs
|
|
|
|
* Only for netbsd-5 branch (later NetBSD GENERIC kernels have it enabled):
|
|
A kernel with the following option is required:
|
|
file-system PUFFS
|
|
pseudo-device putter
|
|
pseudo-device pud
|
|
|
|
*** GlusterFS servers ***
|
|
glusterfs servers will need extended attributes in exported filesystems.
|
|
This is currently only supported in UFS1 (newfs -O1). You will need to
|
|
create the directories below on exported filesystems' roots, and then
|
|
mount with -o extattr
|
|
.attribute/system
|
|
.attribute/user
|
|
|
|
* For netbsd-6 branch and earlier (later NetBSD GENERIC kernels have it),
|
|
the kernel must have the following option enabled:
|
|
options UFS_EXTATTR
|
