issue to access to F5 menu with the console
by Nathanaël Blanchet 23 Mar '15

23 Mar '15

Hi all, I had trouble on a centos vm this morning, and as I used to do, I tried to enter into the interactive boot menu at the begining of the sequence boot so as to deactivate a service. But F5 just balances between the text console and the centos progression bar, and I've not been able yet to access to this menu. I've tried with SPICE and VNC console, but the issue is the same. How can I do this like on any centos system?

Ovirt GusterFS assistance
by Jonathan Mathews 23 Mar '15

23 Mar '15

Hi I am trying to setup an Ovirt, Glusterfs, VM servers. I have followed examples on setting up Ovirt and they have helped me so far, but not the end point that I am looking for. The web sites are: http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/ http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/ http://www.linuxplumbersconf.org/2012/wp-content/uploads/2012/09/2012-lpc-v… I am running 3 HP micro servers and 2 HP DL360 G5 The 3 micro servers are my glusterfs storage and have been provisioned for virt storage. The 2 DL360 are my processing machines. Now my 3 gluster hosts are in one cluster, the volume is in up status and has been provisioned for Virt Storage. But the problem is that my mount point is directed to one server, so when that server goes down, the volume storage domain goes down. I am not sure whether there is a way of mounting it by a "volume identity", so when a server goes down the storage domain stays up. With my 2 processing hosts, I have them in one cluster, but I have not gotten any where with this, as I want the Virtual machines to use the gluster volume as storage but use the processing hosts hardware for processing power. I would appreciate any assistance.

expanding a lun on the san side
by Nathanaël Blanchet 22 Mar '15

22 Mar '15

Hi all, I've just expanded the lun used as master by the domain storage. fdisk on the SPM is able to see the multipath device with its new size, but engine reports the old size. How to refresh this?

Communication errors between engine and nodes?
by Chris Adams 20 Mar '15

20 Mar '15

Setup: oVirt 3.5.1 w/hosted engine, nodes: CentOS 7, engine: CentOS 6 I am periodically seeing errors like this in my engine web UI: 2015-Mar-10, 04:42 Host node5 is not responding. It will stay in Connecting state for a grace period of 89 seconds and after that an attempt to fence the host will be issued. 2015-Mar-10, 04:42 Host node3 from cluster c1 was chosen as a proxy to execute Status command on Host node5. 2015-Mar-10, 04:42 Status of host node5 was set to Up. 2015-Mar-10, 04:42 Host node5 power management was verified successfully. The engine.log file has this: 2015-03-10 04:42:23,310 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.ListVDSCommand] (DefaultQuartzScheduler_Worker-40) [75b9e6d9] Command ListVDSCommand(HostName = node5, HostId = 8dfd0195-f386-4e16-9379-a5287221d5bd, vds=Host[node5,8dfd0195-f386-4e16-9379-a5287221d5bd]) execution failed. Exception: VDSNetworkException: VDSGenericException: VDSNetworkException: Heartbeat exeeded This seems to happen with a random node sometimes. The VMs on the node stay up and don't appear to experience any problem. I can't find any sign of a network problem on either the node, the engine, the node hosting the engine, or the switches. I don't see anything obvious in the logs on any of the systems involved either. The node network setup is VLANs on top of a bond of two NICs, each connected to a different switch in a two-switch stack. -- Chris Adams <cma(a)cmadams.net>
