[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.

I could see that the volume (vol1) was mounted with nfs type. I dismounted the volume and mounted it again in both nodes but using glusterfs type. This time, I could create a 10GB preallocated virtual disk. The events tab showed: 2013-Feb-19, 09:12:39 Add-Disk operation of 'vm1_Disk1' was initiated on VM vm1 by admin@internal. 2013-Feb-19, 09:30:35 The disk 'vm1_Disk1' was successfully added to VM vm1. Too slow, isn't? but worked El 19/02/2013 08:21 a.m., Fernando Ariel Martinez escribió:

why pre-allocate on file based storage? iirc, thin should still be "raw" on file based domains?

I used pre-allocate just for testing. I'll use thin provision. To work around the problem (allocate space for the virtual disk), I installed ovirt according to "Integrating Gluster storage into oVirt" - by Robert Middleswarth. I used a data center with storage type "POSIX compliant FS", but then I found another problem (https://bugzilla.redhat.com/show_bug.cgi?id=835949) which is mentioned by Middleswarth. I used the patch http://gerrit.ovirt.org/#/c/6103/ to fix it. Up to now, it's working. Fernando M. El 20/02/2013 05:54 a.m., Itamar Heim escribió:
