[Users] Ovirt and gluster storage (two servers in a cluster)

Wed Jul 4 04:20:34 UTC 2012

In what may be the reason for my situation? 

In your blog, I have not found any articles on ovirt. Last post by date it
11/17/2011 

In any case, if my situation has been reproduced and you - a sign of a bug
that needs to be identified and transferred to the correction of the
developers.

In what configuration you have installed gluster? Its performance depends on
the choice of operating modes.

Thanks for your help

I am writing a blog post on the steps I did to get it all working.  I have
done it 3 times without issue.  I am doing it a 4th time well writing I had
a lot of problems with Fedora 17 but that was because of Fedora 17 not
oVirt.  Once I switched over to CentOS 6.2 and his build #8 everything just
started working and working very well.  On CentOS 6.2 I found that NFS is
faster then native mode because of Caching over my gigabyte network but both
are slow well provisioning.  

Thanks

I use Scientific linux, and have already installed several times ovirt and
vdsm, but the problem is reproduced.

I sent the logs vdsm, but they do not specify any error.

How do I know what is going wrong?

I would be grateful for any ideas.

I had the same problem with Fedora 17.  I killed everything and started from
scratch using centos and it works fine.  I am wonder if there is the an
issue with the Direct IO support that was added recently to Fedora 17.

Thanks

I can not mount a volume cluster with two servers.

In a separate node activation, gluster volume installed successfully. 

For simultaneous operation of two servers with gluster volume ovirt
constantly switches SPM, without giving an error.

Are you having problems creating a Volume or mounting the volume?

Thanks

I checked the manual work gluster from two hosts. Mounting is working
correctly.

However, in a pair of hosts refuse to work (connection error storage).

Individually, each of their hosts working correctly,

and connects with gluster storage.

I have to manually mount gluster storage? In which folder?

You can write that how-to add a server to an existing cluster of gluster?

Hi.

I use ovirt 3.1 and gluster storage.

I added the two servers in a cluster. 

And faced with the problem of their joint work with gluster storage.

Storage not initialized, although on one server working successfully with
gluster storage.

Vdsm log an attachment

(vdsm-6.log - node -1)

(vdsm-7.log - node -2)

You have to tweak you ipstates table to allow glusterd to talk to the other
box glusterd and you have to manually peer the systems together.
