Hello, Which iso should I use to install an ovirt-node ? What the difference between the el and fc versions. (I'm installing the engine on a centos 6.5 minimal server.) Which version should I use. Kind regards.

(if you enabled it before installing them, or re-install[1] post enabling gluster mode, it should have deployed vdsm-gluster as well) [1] after moving hos to maintenance.

The host moving to Non-Operational state with error "Gluster command failed..." is dependent on whether "Enable gluster service" is checked on your cluster. This check indicates that you also want to manage gluster storage provisioning on the nodes. A recent change now checks that vdsm-gluster support is available for such clusters. That's probably why you are seeing this error after update. > > > Regards, > René >

[Users] method "glusterHostsList" is not supported
by René Koch 04 Mar '14

Hi list, My hosted engine is running again, so I want to start a new thread for another issue with my setup. I have a GlusterFS storage domain, which can be mounted from CLI without problems. oVirt is 3.4 from ovirt-3.4.0-prerelease repository running on CentOS 6.5 with latest updates (both OS and oVirt). Both hosts, which act as hypervisors and GlusterFS nodes are in state "Non Operational" in oVirt because "Gluster command [Non interactive user] failed on server ovirt-host02.dmz.linuxland.at." In engine.log I see the entry "glusterHostList is not supported" (attached are the log entries when activating one of the hosts): 2014-03-03 18:17:11,764 ERROR [org.ovirt.engine.core.vdsbroker.gluster.GlusterServersListVDSCommand] (org.ovirt.thread.pool-6-thread-21) [6eee3cbd] Command GlusterServersListVDSCommand(HostName = ovirt-host02.dmz.linuxland.at, HostId = dd399eeb-f623-457a-9986-a7efc69010b2) execution failed.

[Users] Creating Logical Network issue - API
by Tejesh M 03 Mar '14

03 Mar '14

Hi , I'm trying to create Logical Network and assign it to cluster & want to bond this to one of the Network Interface on Host. so that i can isolate my VM from other networks. The issue is even if i set Cluster while creating Logical Network, it is not setting the cluster. In Web Admin it is in unset state. Also, let me know how do i bind this Logical network on Host Interface. *Java code:* Network nw1=new Network(); VLAN vlan = new VLAN(); vlan.setId(2000); nw1.setVlan(vlan); IP ip = new IP(); ip.setAddress("192.168.1.151"); ip.setGateway("192.168.1.1"); ip.setNetmask("255.255.255.0"); nw1.setIp(ip); nw1.setName("apiNetwork"); nw1.setDataCenter(api.getDataCenters().get("testDC")); nw1.setCluster(api.getClusters().get("testCluster")); org.ovirt.engine.sdk.decorators.Network nw2 = api.getNetworks().add(nw1); -- Thanks & Regards Tejesh
