Possible to use libgfapi with libvirt in CentOS 6.5?
Good Evening,
I have read that libgfapi has been backported to qemu-kvm in RHEL 6.5 (and
by virtue CentOS and SL). However I am unable to figure out how to actually
make it work as described. Virt-manager still only seems to support
glusterfs volumes via fuse.
I can use qemu-img to create a disk image on gluster://<server>/<Volume>.
But virt-manager can only use it from a fuse

libvirt and libgfapi in RHEL 6.5 beta
Dear All,
Very pleased to see that the Redhat 6.5 beta promises "Native Support
for GlusterFS in QEMU allows native access to GlusterFS volumes using
the libgfapi library"
Can I ask if virt-manager & libvirt can control libgfapi mounts? :)
or do I need to use ovirt? :(
many thanks

does libgfapi and fuse mount performance matches?
Dear gluster experts,
I recently want to use jna to bind libgfapi to java. And I have one
question. Does libgfapi and fuse mount performance match? The
performance translators works for libgfapi too?
Thank you very much.

libgfapi disk locking in virtlockd not working
Hello.
I'm playing with libgfapi network disks, over IB and all is working
fine, but not disk locking (and true rdma transport).
I use virtlockd, and with fuse mount, locking works as expected.
But when i converted disk definitions to libgfapi, locks are not created
(but qemu starts and works fine). I used direct and indirect locking -
same result : qemu working fine, no locks.

Qemu-Libgfapi: periodical shutdown of virtual machines.
Hello,
Would you so kind to help me with my problem concerning libgfapi.
My host operating system is Ubuntu 14.04 LTS, version of glusterfs is
3.6.2, and version of qemu is 2.0.0.
In our environment guest virtual machines periodically go to power-off
state 'Powered Off'(Shutdown) with ERROR in /var/log/syslog like:

libgfapi with encryption?
Hi,
I created an encrypted volume which appears to be working fine with
FUSE but the volume is supposed to store VM images (master key in
place). I noticed some references in libgfapi source code to
encryption so I decided to try it out. While attempting to create an
image:
# qemu-img create -f qcow2 gluster://gluster01/virt0/testing.img 30G

High Guest CPU Utilization when using libgfapi
Hi,
I am currently testing running Openstack instance on Cinder volume with
libgfapi. This instance is the Windows instance and i found that when
running random 4k write workload, the CPU utilization is very high, 90%
CPU utilization with about 86% in privileged time. I also tested the
workload with volume from NFS and the CPU utilization is only around 5%.
For gluster fuse, the CPU utilization

writeLines + foreach/doMC
Hi
I'm processing sequencing data trying to collapsing the locations of each

will require 10GB mem at least)
so I wrote a function that, given a sequence id, provide the needed line to
be stored

Latest glusterfs 3.8.5 server not compatible with livbirt libgfapi access
Hi,
After updating glusterfs server to 3.8.5 (from Centos-gluster-3.8.repo) the
KVM virtual machines (qemu-kvm-ev-2.3.0-31) that access storage using
libgfapi are no longer able to start. The libvirt log file shows:

Expand replicated bricks to more nodes/change replica count
Hi list
I have set up several volumes on a two-node Gluster setup using
"replica 2" configurations. I would like to add two more nodes to the
trusted pool so that all volumes are replicated on 4 nodes. I wonder
if that can be done online, but after doing some research on this I
didn't find evidence that it's possible to change the replica count

Upgrade Gluster 3.7 to 3.12 and add 3rd replica [howto/help]
Hello all fellow GlusterFriends,
I would like you to comment / correct my upgrade procedure steps on replica 2 volume of 3.7.x gluster.
Than I would like to change replica 2 to replica 3 in order to correct quorum issue that Infrastructure currently has.
Infrastructure setup:
- all clients running on same nodes as servers (FUSE mounts)
- under gluster there is ZFS pool running as raidz2 with SSD

Adding/Removing bricks/changing replica value of a replicated volume (Gluster 3.2.1, OpenSuse 11.3/11.4)
Hi!
Until now, I use Gluster in a 2-server setup (volumes created with
replica 2).
Upgrading the hardware, it would be helpful to extend to volume to
replica 3 to integrate the new machine and adding the respective brick
and to reduce it later back to 2 and removing the respective brick when
the old machine is cancelled and not used anymore.
But it seems that this requires to delete and

Creating cluster replica on 2 nodes 2 bricks each.
Hello
We are trying to setup Gluster for our project/scratch storage HPC machine using a replicated mode with 2 nodes, 2 bricks each (14tb each).
Our goal is to be able to have a replicated system between node 1 and 2 (A bricks) and add an additional 2 bricks (B bricks) from the 2 nodes. so we can have a total of 28tb replicated mode.
Node 1 [ (Brick A) (Brick B) ]
Node 2 [ (Brick A) (Brick

Upgrade Gluster 3.7 to 3.12 and add 3rd replica [howto/help]
Procedure looks good.
Remember to back up Gluster config files before update:
/etc/glusterfs
/var/lib/glusterd
If you are *not* on the latest 3.7.x, you are unlikely to be able to go
back to it because PPA only keeps the latest version of each major branch,
so keep that in mind. With Ubuntu, every time you update, make sure to
download and keep a manual copy of the .Deb files. Otherwise you
