Hi,

You can also use the below method on every gluster node :-

For Group-virt (optimize for virt store)

1. Create the file name /var/lib/glusterd/groups/virt
2. And paste all the contents from this location to this file :- https://raw.githubusercontent.com/gluster/glusterfs/master/extras/group-virt.example
3. service glusterd restart
4. service vdsmd restart

--------------
quick-read=off
read-ahead=off
io-cache=off
stat-prefetch=off
eager-lock=enable
remote-dio=enable
quorum-type=auto
server-quorum-type=server
--------------

Thanks,
Punit Dambiwal

Hello,

I've been struggling to set up an Ovirt cluster and am now bumping into
this problem:

When I try to create a new (Gluster) storage domain, it fails to attach
to the data center. The error on the node from vdsm.log:

My oVirt version: 3.4.2-1.el6 (CentOS 6.5)
The hypervisor hosts run GlusterFS 3.5.0-3.fc19.(Fedora 19)
The two storage servers run GlusterFS 3.5.0-2.el6 (Centos 6.5)

So I am NOT using local storage of the hypervisor hosts for the
GlusterFS bricks.

What can I do to solve this error?

By the way, the options on the GlusterFS volume are as follows:

Volume Name: vmimage
Type: Replicate
Volume ID: 348e1d45-1b80-420b-91c2-93f0d764f227
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 192.168.10.120:/export/gluster01/brick
Brick2: 192.168.10.149:/export/gluster01/brick
Options Reconfigured:
network.ping-timeout: 10
cluster.quorum-count: 1
cluster.quorum-type: auto
server.allow-insecure: on
storage.owner-uid: 36
storage.owner-gid: 36

OK, fixed it. For someone else's reference, I had to set the following
options on the gluster volume:

network.remote-dio: on
performance.io-cache: off
performance.read-ahead: off
performance.quick-read: off
cluster.eager-lock: enable

Apparently that's done by the 'optimize for virt store' checkbox, but
obviously not when the volume is created manually. Having this in the
documentation on ovirt.org would have saved me a lot of time and
frustration.



its a wiki, how about adding this for the next guy?

thanks,
