(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

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. Exception: VDSNetworkException: org.apache.xmlrpc.XmlRpcException: <type 'exceptions.Exception'>:method "glusterHostsList" is not supported Can you give me a hint what this means and how I can activate my hosts and storage again?

[Users] Creating Logical Network issue - API
by Tejesh M 04 Mar '14

04 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

[Users] hosted engine setup (network)

Hi, During hosted engine setup I faced issues with network configuration on my CentOS 6.5 hosts: My network setup was the following which doesn't work with hosted engine setup: - eth0.200 (VLAN tag 200) should become ovirtmgmt interface - GATEWAY is in /etc/sysconfig/network and not in ifcfg-eth0.200 The following errors occured: 014-02-25 15:42:31 INFO otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189 Configuring the management bridge 2014-02-25 15:42:31 DEBUG otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:198 getVdsCaps for eth0: {'addr': '', 'cfg': {'DEVICE': 'eth0', 'PEERDNS': 'no', 'NM_CONTROLLED': 'no', 'BOOTPROTO': 'none', 'HWADDR': '00:25:9 0:75:87:C2', 'ONBOOT': 'yes'}, 'ipv6addrs': ['fe80::225:90ff:fe75:87c2/64'], 'mtu': '1500', 'netmask': '', 'hwaddr': '00:25:90:75:87:c2', 'speed': 1000} 2014-02-25 15:42:31 DEBUG otopi.context context._executeMethod:152 method exception Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/otopi/context.py", line 142, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/ovirt-hosted-engine-setup/network/bridge.py", line 231, in _misc 'gateway=%s' % caps['cfg']['GATEWAY'], KeyError: 'GATEWAY' This can be solved by setting GATEWAY in ifcfg-eth* file instead of /etc/sysconfig/network Next, VLAN tagged interfaces don't work: 2014-02-25 15:35:20 INFO otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189 Configuring the management bridge 2014-02-25 15:35:20 DEBUG otopi.context context._executeMethod:152 method exception Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/otopi/context.py", line 142, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/ovirt-hosted-engine-setup/network/bridge.py", line 194, in _misc ].s.getVdsCapabilities()['info']['nics'][nics] KeyError: 'eth0.200' So I had to do the following: - Set switch port to untagged for this VLAN - Configure eth0 instead of eth0.200 - Run hosted engine setup - Configure VLAN for ovirtmgmt in oVirt (which surprisingly worked for an active interface) - Configure VLAN tagging on hosts - Reconfigure switch ports - Sync networks in oVirt network setup tab As this was a real pain to do I would love to see support for VLAN tagging in hosted engine setup :) Shall I open bug reports for these 2 issues or are they already known? -- Best Regards René Koch Senior Solution Architect ============================================ LIS-Linuxland GmbH Brünner Straße 163, A-1210 Vienna Phone: +43 1 236 91 60 Mobile: +43 660 / 512 21 31 E-Mail: rkoch(a)linuxland.at ============================================

See e.g. http://man7.org/linux/man-pages/man5/proc.5.html Is the above on a node? engine? both nodes are similar? If so, that's not the reason for the "no space left on device". If this error is reproducible, you can try to find the process that this happens to (perhaps libvirtd, vdsmd, or the hosted-engine ha daemon) and do: strace -f -o /tmp/trace1 -tt -s 512 -p PID where PID is the pid of that process, then search /tmp/trace1 for 'no space left on device' and see the exact call that failed. -- Didi
