[Users] host non responsive in a 1 host DC with 1 vm
by Neil 01 Apr '13

01 Apr '13

Hi guys, I've got a test oVirt setup with only 1 host and 1 test VM but I had a power failure and the host is now non responsive, despite being able to log into it via SSH. Manually fencing results in a.... "Manual fence did not revoke the selected SPM (ovirthosttest) since the master storage domain was not active or could not use another host for the fence operation." When I try put the host into maintenance I get ..."Manual fence did not revoke the selected SPM (ovirthosttest) since the master storage domain was not active or could not use another host for the fence operation." When I try and activate the data domain I get... "Failed to activate Storage Domain MAIN (Data Center Default) by admin@internal". My VM was in an unknown state, but considering I'd already had a power failure, I logged into my oVirt engine postgres command line and ran "update vm_dynamic set status = 0 where vm_guid = (select vm_guid from vm_static where vm_name = 'zimbra');" to try and force my VM into a down state, but that hasn't helped either. I'd imagine that if I had another host to add to the cluster SPM would hopefully move to the new host and the problem would disappear, but I don't have one unfortunately. Any suggestions? Centos 6.4 vdsm-python-4.10.3-0.31.20.el6.x86_64 vdsm-4.10.3-0.31.20.el6.x86_64 vdsm-cli-4.10.3-0.31.20.el6.noarch vdsm-xmlrpc-4.10.3-0.31.20.el6.noarch libvirt-lock-sanlock-0.10.2-18.el6.x86_64 libvirt-client-0.10.2-18.el6.x86_64 libvisual-0.4.0-9.1.el6.x86_64 libvirt-python-0.10.2-18.el6.x86_64 libvirt-0.10.2-18.el6.x86_64 On my engine it's Centos 6.4 with ovirt-engine-3.2.0-1.39.el6.noarch My engine has an NFS shared RAID array which the hosts the entire data domain. I could can the entire install and start again, but I'd prefer to avoid doing that if possible as I'm still in the process of migrating email to my zimbra VM. Any help is appreciated greatly. Thanks. Regards. Neil Wilson.

[Users] 2 node cluster with local storage?
by russell muetzelfeldt 01 Apr '13

01 Apr '13

Hi All, Is there any supported way (or advice on the best unsupported way) to provision a 2-node cluster using local storage? I've deployed RHEV 3.0 against both NFS and FC storage, and would like to bring up a 2 node oVirt 3.2 playground. I don't have access to a real storage server for this setup, but the hypervisor nodes have several spindles of 15K RPM SAS drives each so I'm assuming I can use DRBD and bond some 1GBPS ether links to provide a shared block device with adequate performance. Ideally I'd like to use the regular CLVM storage pool but on local DRBD instead of FC, but I don't see any way to make oVirt use a volume group that it didn't create itself. Another possibility would be POSIX FS on GFS2 which looks like it should be supported but (afaict) would require doubling up on the cluster management layer. Is there any way (even if not "production ready") to have a storage pool use a clvm vg that has been created outside of oVirt? Has anyone used the POSIX FS pool type against GFS2? Any other suggestions about how to put this together? cheers Russell

[Users] Issues using local storage for gluster shared volume
by Tony Feldmann 01 Apr '13

01 Apr '13

I have been trying for a month or so to get a 2 node cluster up and running. I have engine installed on the first node, then add each each system as a host to a posix dc. Both boxes have 4 data disks. After adding the hosts I create a distributed replicate volume using 3 disk from each host with ext4 filesystems. I click the 'optimize for virt' option on the volume. There is a message in events that says that it can't set a volume option, then it sets 2 volume options. Checking the options tab I see that it added the gid/uid options. I was unable to find in the logs what option was not set, I just see a message about usage for volume set <volname> <option>. The volume starts fine and I am able to create a data domain on the volume. Once the domain is created I try to create a vm and it fails creating the disk. Error messages are along the lines of task file exists and can't remove task files. There are directories under tasks and when trying to manually remove them I get the "directory not empty" error. Can someone please shed some light on what I am doing wrong to get this 2 node cluster with local disk as shared storage up and running? Thanks, Tony

[Users] ldap
by Ryan Wilkinson 28 Mar '13

28 Mar '13

I'm able to set up Active Directory authentication if my ovirt engine is set to use dns that is hosted on the same system as Active Directory. However, if I use static host entries in my engine "hosts" file instead of using dns I'm getting the error "ldap server for domain not found" when I issue the command: "engine-manage-domains -action=add -domain=’ovirt.local' -user='admin' -provider=ActiveDirectory -interactive" from the engine. I've googled to death how to configure static entries on my engine system for the ldap server and it seems that I need to configure my nsswitch and ldap.conf files but still no luck... Any ideas??
