Thanks for an update. Can I have KVM hypervisors also function as storage nodes
for glusterfs? What is a release date for glusterfs support? We're looking for
a production deployment in June. Thanks
current status is
1. patches for provisioning gluster clusters and volumes via ovirt are
in review, trying to cover this feature set [1].
I'm not sure if all of them will make the ovirt 3.1 version which is
slated to branch for stabilization June 1st, but i think "enough" is there.
so i'd start trying current upstream version to help find issues
blocking you, and following on them during june as we stabilize ovirt
3.1 for release (planned for end of june).
2. you should be able to use same hosts for both gluster and virt, but
there is no special logic/handling for this yet (i.e., trying and
providing feedback would help improve this mode).
I would suggest start from separate clusters though first, and only
later trying the joint mode.
3. creating a storage domain on top of gluster:
- expose NFS on top of it, and consume as a normal nfs storage domain
- use posixfs storage domain with gluster mount semantics
- future: probably native gluster storage domain, up to native
integration with qemu
can you please describe the use case you are trying to accommodate?
thanks,
Itamar

Already know the date when it is added support for glusterfs?
I can work with the test in a test version of glusterfs?
there are two parts to the support:
1. managing the gluster hosts/storage/volumes - patches for different
parts of this in gerrit - but not needed for first phase of using this.
2. using gluster as a posix fs - vdsm side is ready, and iirc, engine
done by laszlo who can share when test patches can be used for testing this
Small correction - patches are not at gerrit (referring to Posix FS at
engine side)
3. integrating both together - a bit later :)

Good news.
It already works in a test version or development has not yet begun?
early patches to build this support are sent now to engine/vdsm.
so work has begun, but not working yet

Hi.
Test the ability to work as a storage server glusterfs. Direct
support to glusterf ovirt unfortunately not.
This feature will be added in the future?
I'll let someone else reply on the below, but as for ovirt-gluster
integration - yes, it is in the works.
this gives a general picture of the work being carried out:
http://www.ovirt.org/wiki/AddingGlusterSupportToOvirt
Attempted to implement a scheme of work -> glusterfs mounted on a
node in a folder mount glusterfs connected via NFS to ovirt.
It works =)
Now try to mount NFS to 127.0.0.1 and encountered an error:
Command:
[root@noc-4-m77 ~] # / bin / mount-o soft, timeo = 600, retrans = 6,
nosharecache, vers = 3 -t nfs 127.0.0.1 :/share/tmp /tmpgcOezk
Error:
mount.nfs: Unknown error 521
NFS V4 is disabled.
In this mount:
/bin/mount -t nfs 127.0.0.1:/share/ tmp/tmpgtsoetsk is successful.
I understand that this is not a problem ovirt, but you might prompt
any ideas how to fix it?
To use glusterfs in overt to execute a commandL
Mount -t glusterfs -o log-level = WARNING, log-file =
/var/log/gluster.log noc-1 :/mht / /share
I can prescribe it in vdsm that it was carried out instead of
/bin/mount-o soft, timeo = 600, retrans = 6, nosharecache, vers = 3
-t nfs 127.0.0.1:/share/tmp/tmpgtsOetsk
