Storage question: single node gluster?
by Alan Murrell 18 Jul '15

18 Jul '15

Hi There, This is not strictly oVirt, but is storage-related, so hopefully you will indulge me? Is there any detriment (performance or otherwise) in setting up a single-node glusterFS storage? I know glusterFS is designed to be used with multiple nodes, but I am wondering if there are any ill-effects in configuring current storage as a single-node cluster, with the idea of possibly adding future nodes in the future? Thanks! :-) -Alan

reinstall hosted-engine with ovirt 3.5?
by Alastair Neil 18 Jul '15

18 Jul '15

Due to a moment of idiocy I accidentally upgraded my hosted-engine vm to Fedora 22 and now ovirt-engine will not start, I was able to get postgesql up an running so I was able to make a backup of the engine. As far as I know Ovirt 3.5 is not supported on F22, so my options seem limited. 1, update to the 3.6 prerelease 2, reinstall the VM, if I were doing this I would use CentOS 7 my preference would be to fresh install the hosted-engine. I am guessing the way to go about this would be to shutdown the HE broker and agent daemons on all the nodes, possibly clean the metadata? and the do a hosted engine deploy as though migrating from an external engine. Can anyone comment if this is reasonable? Thanks, -Alastair

Migrate hosted-engine from NFS to ISCSI
by Christoph Sieghart 17 Jul '15

17 Jul '15

Dear list, we are running an ovirt 3.5 cluster with 3 nodes and about 50 vms. The ovirt engine is deployed as a hosted engine with NFS storage. oVirt 3.5 now supports ISCSI as storage backed for the hosted engine and we would like to move our hosted-engine to ISCSI. Is there any way to migrate the existing engine from NFS to ISCSI? If no migration path exists, is there a way to reinstall the engine without disruption to the cluster? best regards, Christoph

Problem with Mac Spoof Filter
by InterNetX - Juergen Gotteswinter 17 Jul '15

17 Jul '15

Hi, seems like the Setting EnableMACAntiSpoofingFilterRules only applies to the main IP of a VM, additional IP Adresses on Alias Interfaces (eth0:x) are not included in the generated ebtables ruleset. Is there any Workaround / Setting / whatever to allow more than one IP without completly disabling this Filter? Thanks, Juergen

hosted_engine, fencing does not work
by martirosov.d 16 Jul '15

16 Jul '15

Hi. ovirt3.5 Have two servers(node1 and node2) that are runnig Centos6.6. 1. engine on node2. Disables network node1, engine restarts after some time node1 and everything works fine. 2. engine on node1. Disables network node1, engine moved to node2, node1 but does not reset, although attempts. That log messages: 2015-Jul-03, 10:42 Host node1 is not responding. It will stay in Connecting state for a grace period of 120 seconds and after that an attempt to fence the host will be issued. 2015-Jul-03, 10:39 Host node1 is not responding. It will stay in Connecting state for a grace period of 120 seconds and after that an attempt to fence the host will be issued. 2015-Jul-03, 10:36 Host node1 is not responding. It will stay in Connecting state for a grace period of 120 seconds and after that an attempt to fence the host will be issued. 2015-Jul-03, 10:34 User admin@internal logged in. 2015-Jul-03, 10:33 Host node1 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" 2015-Jul-03, 10:33 Host node2 from cluster emk-cluster was chosen as a proxy to execute Status command on Host node1. 2015-Jul-03, 10:33 Host node1 is non responsive. Manual fencing to node1 works from the node2: # fence_ipmilan -A password -i 10.64.1.103 -l admin -p *** -o status Getting status of IPMI:10.64.1.103...Chassis power = On Done Power Management on node2 test succeeded in oVirt Manager. i.e. If turn off the host on which the engine, after moving to a healthy host, engine does not fencing to a problematic host and all VMs that were on problematic host does not migrate. If the problem is not with the host on which the engine, then it works: making fence, and migrates Vms.
