Expand an ovirt+glusterfs cluster
by Davide Ferrari 23 Mar '17

23 Mar '17

Hello I have a 4 node oVirt 4.0 cluster running on top of glusterfs volumes, managed by the oVirt cluster (option ticked in the cluster properties) Now, I'm adding several new nodes to this cluster with a better CPU (Broadwell vs Haswell) but now comes the "bad" part. Out of enthusiasm I've already added storage from these new servers to the data volume already present and used by the current cluster. In fact now ovirt has detected new hosts and it's asking me if I want to add these host to the cluster. But there are two problems: 1) I want to create a new, Broadwell cluster 2) I'm using a separate VLAN+domain name for gluster, and oVirt is proposing me to use the gluster (storage) domain names as the new hosts identifier. What are the right steps/actions to take now? It's a running production system. Thanks in advance -- Davide Ferrari Senior Systems Engineer

ovirt 4.1 - mount recovery iso for failing vm ?
by Ian Neilsen 23 Mar '17

23 Mar '17

Guys I've spent the day reading any and all content on recovering a failing to boot vm under ovirt 4.1 and am finding many cmds are deprecated , old processes no longer work. What is the correct way to mount an iso to perform recovery on a boot partition of a failing VM in oVirt 4.1? vm.conf, virsh, virt-edit, vmhost.xml, vdsClient, new vda, way too many options and no singular right way to do this that works well. -- Ian Neilsen Mobile: 0424 379 762 Linkedin: http://au.linkedin.com/in/ianneilsen Twitter : ineilsen

how to handle mount options for hosted engine on glusterfs
by /dev/null 23 Mar '17

23 Mar '17

Hi, how do i make the hosted_storage aware of gluster server failure? In --deploy i cannot provide backup-volfile-servers. In /etc/ovirt-hosted-engine/hosted-engine.conf there is an mnt_options line, but i read (https://github.com/oVirt/ovirt-hosted-engine-setup/commit/995c6a65ab897d804…) that this settings get lost during deployment on seconday servers. Is there an official way to deal with that? Should this option be set manualy on all nodes?

How to set priority for HA VM via Python SDK ?
by TranceWorldLogic . 23 Mar '17

23 Mar '17

Hi, I want to set priority of Highly Available VM as High via python SDK. I provided information as shown below: vm = self.vms_service.add( vm = types.Vm ( high_availability = types.HighAvailability( enabled = True, priority = 1, ), ), ) As see above priority we have to provide as number but in GUI we can choose drop down menu as ("LOW", "MID" and "HIGH"). I wan to set priority as "HIGH", which integer value I have to set in priority ? I tried with 1 and 3 it shows "LOW" in both cases. Please help me. Thanks, ~Rohit

no vm.conf?
by Michael Kleinpaste 22 Mar '17

22 Mar '17

Hello all, I wanted to adjust the hosted-engine VM to use a little less CPU and memory. However, none of my hosts have the vm.conf file in /etc/ovirt-hosted-engine-ha/ as instructions say it should be. Has the process for changing the hosted-engine VM settings been changed with 4.1? -- *Michael Kleinpaste* Senior Systems Administrator SharperLending, LLC. www.SharperLending.com Michael.Kleinpaste(a)SharperLending.com (509) 324-1230 Fax: (509) 324-1234

OSSEC reporting hidden processes
by Charles Kozler 22 Mar '17

22 Mar '17

Hi - I am wondering why OSSEC would be reporting hidden processes on my ovirt nodes? I run OSSEC across the infrastructure and multiple ovirt clusters have assorted nodes that will report a process is running but does not have an entry in /proc and thus "possible rootkit" alert is fired I am well aware that I do not have rootkits on these systems but am wondering what exactly inside ovirt is causing this to trigger? Or any ideas? Below is sample alert. All my google-fu turns up is that a process would have to **try** to hide itself from /proc, so curious what this is inside ovirt. Thanks! ------------- OSSEC HIDS Notification. 2017 Mar 20 11:54:47 Received From: (ovirtnode2.mydomain.com2) any->rootcheck Rule: 510 fired (level 7) -> "Host-based anomaly detection event (rootcheck)." Portion of the log(s): Process '24574' hidden from /proc. Possible kernel level rootkit. --END OF NOTIFICATION ------------
