Hey guys I wanted to know if anyone ever recieved this error before "Error while executing action: Cannot add Host. Host with the same address already exists" when trying to re-add a Host that you deleted? I think the host maybe partially deleted or have records somewhere. Let me know if anyone can help? Thanks,

question regarding fencing proxies
by cmc 14 Jan '17

14 Jan '17

Hi, Can someone tell me how the engine decides which power management proxy/proxies to use (using default cluster/dc config)? I am using drac 7 for a fence agent in my two host cluster, and have noticed that one of the hosts cannot contact the drac. My guess is that the engine is using one host to as a power management proxy and hosts cannot reach their own drac as they are on the same interface + vlan. Example scenario: Engine uses host 2 as power management proxy. It can contact host 1’s drac, but cannot contact its own drac. In the case of host 2 being unreachable/kdumping etc, would the engine switch to use host 1 as the proxy to contact host 2’s drac? Thanks, Cam PS: I'd like to use the APC as an additional fencing agent, each host has two PSUs connected to two different APCs. Is there a guide on how to specify two ports on two different PDUs to control power on a host?

vdsm IOProcessClient WARNING Timeout waiting for communication thread for client
by Bill James 13 Jan '17

13 Jan '17

We have an ovirt system with 3 clusters, all running centos7. ovirt engine is running on separate host, ovirt-engine-3.6.4.1-1.el7.centos.noarch 2 of the clusters are running newer version of ovirt, 3 nodes each, ovirt-engine-4.0.3-1.el7.centos.noarch, glusterfs-3.7.16-1.el7.x86_64, vdsm-4.18.11-1.el7.centos.x86_64. 1 cluster is still running the older version, ovirt-engine-3.6.4.1-1.el7.centos.noarch. Yes we are in the process of upgrading the whole system to ovirt4.0, but takes time.... One of the 2 clusters running ovirt4 is complaining of timeouts, vdsm talking to gluster. No warnings on the 2 other clusters.

Unable to delete VM disk
by cmc 13 Jan '17

13 Jan '17

Hi, I'm trying to delete a disk from a host I have shut down, as I need to provision a larger one. When I try to delete it, it gives me an exception on the UI. I've tried removing the bootable flag, and creating another disk, but it still won't allow the deletion of the disk. I can't see a relevant error in the engine log, though there are errors in the UI log, but I expect that is just as result of the underlying issue with deleting the disk. Thanks, Cam

Hosted Engine: Add another host
by gregor 13 Jan '17

13 Jan '17

Hi, I have a hosted-engine setup on one host. Today I try to add another host from the UI but this gives me some errors without detail. Is there a way to add a new host from the shell? Not a node [1] because I plan to use docker as well on the host, it's a test environment. Or is it better to install the host as node? cheers gregor [1] http://www.ovirt.org/node/

That will take care of DB and configurations. Make sure the status of your Ovf_store disks is OK with no event of warning on them(this means you have cold backup of your VM config) You can then just start the upgrade , your VMS will continue with no interference.

Specifying the datastore on a VmPool creation via Python-SDK?
by nicolas＠devels.es 12 Jan '17

12 Jan '17

Hi, We've several templates that have their disks replicated (copied) on all our Storage Domains. Problem is that we create our VmPools using PythonSDK, and it usually creates the pool on one of our Storage Domains that has a small amount of free disk space. Some of the Data Stores have plenty of space and when creating the VmPool, we'd like to be able to specify on which of these Storage Domains to create the VmPool. So far I see no parameter on the params.VmPool class to do that. I've tried using an Action, but the request is not correct: action = params.Action(storage_domain=api.storagedomains.get(name='...')) pool = params.VmPool(name='testlarge', cluster=api.clusters.get(name='...'), template=api.templates.get(name='Blank'), max_user_vms=1, size=1, type_='manual', actions=action) pool = params.VmPool(name='testlarge', cluster=api.clusters.get(name='...'), template=api.templates.get(name='Blank'), max_user_vms=1, size=1, type_='manual', actions=[action]) api.vmpools.add(pool) Both tries fail. This is Python-SDK 3.x. Is there a way to specify the destination Storage Domain onto where to create the VmPool? Thanks
