[Users] 3.1 and centos 6.3 problem

I have installed ovirt 3.1 according to the instructions in "Integrating Gluster storage into oVirt" - by Robert Middleswarth, linked in http://wiki.ovirt.org/Documentation. I was able to complete the instructions successfully but I have problems when a need to create a VM. Especifically when I need to allocate space for the virtual disk. I have: 1 ovirt engine server, (admin) 2 nodes, IBM System x 3650M3 (nodo1, nodo2) 1 switch cisco SG 300-20 (to connect them) I created a VM (vm1). When I add a 10GB preallocated disk to vm1, after a few seconds the ovirt engine server loses the connection with the node SPM. I can see in the events tab "Invalid status on Data Center Default. Setting status to Non-Responsive." Then, the SPM changes to the other node. At last, in the events tab I can see "Operation Add-Disk failed to complete on VM vm1." I have set SELinux in permissive mode. I have also disabled iptables. In the ovirt engine server there are an ISO domain, called iso, (NFS Export Path: admin.cluster:/nfs/iso) and an Export domain, called exp, (NFS Export Path: admin.cluster:/nfs/export). In each node with gluster, the /data directory is used to create the volume vol1 (type: Replicate) The Data domain is called vms (NFS Export Path: localhost:/vol1). Some help wil be appreciated Fernando M. -- --------------------------------------------------- Lic.
