removing FC storage
by David David 08 Oct '18

How to remove FC storage domain correctly? I turned off the FC storage domain in the cluster (maintenance -> detach -> remove), but the volume group still remained on the hosts and I would have to remove them manually and need to clear a multipath links too, before I turn off the LUN on the FC storage. How will the cluster behave if there are differences in the volume groups on the hosts? Because I can’t simultaneously delete partitions and multipath links on all hosts, and this process will occur sequentially on each host.

Hi, The task "Adding disk" is stuck at "creating volume". I tried to delete the task with "taskcleaner.sh", at CLI with list / remove jobs, deleted lastly the VM and restartet the engine-vm. But its still in the task list. Any idea to remove this job?

New oVirt deployment suggestions
by Stefano Danzi 08 Oct '18

08 Oct '18

Hello! I'm almost ready to start with a new oVirt deplyment. I will use CentOS 7, self hosting engine and glusert storage. I have 3 phisical host. Each host has four NIC. My first idea is: - configure bond betwheen NICs - configure a VLAN interface for management network (and local lan) - configure a VLAN interface for gluster network - configure gluster for the hosted engine - start "hosted-engine --deploy" process is this enough? do I need a phisical dedicated NIC for management network? Bye

When I use the VM Portal and invoke a console I'm not sure how i can leverage the html5 noVNC version of this. I can only get the .vv file and would like to use a web based console, or rather provide them to users of an engine. TIA Brian

Hello Everybody, I only wanted to ask you, if the ovirt hosts does need the cockpit-networkmanager? I ask because I can not updates my CentOS hosts, I get always the message: Transaction check error: file /usr/share/cockpit/networkmanager/manifest.json from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch file /usr/share/cockpit/networkmanager/po.ca.js.gz from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch file /usr/share/cockpit/networkmanager/po.cs.js.gz from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch ... When I remove the cockpit-networkmanager the error is gone, but after making a yum update I'm not able to reinstall the cockpit-networkmanager because it is still want to use the old version.

master domain wont activate
by Vincent Royer 06 Oct '18

06 Oct '18

I was attempting to migrate from nfs to iscsi storage domains. I have reached a state where I can no longer activate the old master storage domain, and thus no others will activate either. I'm ready to give up on the installation and just move to an HCI deployment instead. Wipe all the hosts clean and start again. My plan was to create and use an export domain, then wipe the nodes and set them up HCI where I could re-import. But without being able to activate a master domain, I can't create the export domain. I'm not sure why it can't find the master anymore, as nothing has happened to the NFS storage, but the error in vdsm says it just can't find it: StoragePoolMasterNotFound: Cannot find master domain: u'spUUID=5a77bed1-0238-030c-0122-0000000003b3, msdUUID=d3165759-07c2-46ae-b7b8-b6226a929d68' 2018-10-03 22:40:33,751-0700 INFO (jsonrpc/3) [storage.TaskManager.Task] (Task='83f33db5-90f3-4064-87df-0512ab9b6378') aborting: Task is aborted: "Cannot find master domain: u'spUUID=5a77bed1-0238-030c-0122-0000000003b3, msdUUID=d3165759-07c2-46ae-b7b8-b6226a929d68'" - code 304 (task:1181) 2018-10-03 22:40:33,751-0700 ERROR (jsonrpc/3) [storage.Dispatcher] FINISH connectStoragePool error=Cannot find master domain: u'spUUID=5a77bed1-0238-030c-0122-0000000003b3, msdUUID=d3165759-07c2-46ae-b7b8-b6226a929d68' (dispatcher:82) 2018-10-03 22:40:33,751-0700 INFO (jsonrpc/3) [jsonrpc.JsonRpcServer] RPC call StoragePool.connect failed (error 304) in 0.17 seconds (__init__:573) 2018-10-03 22:40:34,200-0700 INFO (jsonrpc/1) [api.host] START getStats() from=::ffff:172.16.100.13,39028 (api:46) When I look in cockpit on the hosts, the storage domain is mounted and seems fine.

Bad libvirt-spice certificate - regenerate?
by Chris Adams 05 Oct '18

05 Oct '18

I have an oVirt 4.1 cluster that was initially installed with 3.5 in 2014. The SSL certificates on the physical hosts in /etc/pki/vdsm/libvirt-spice have a problem - the "not before" date is invalid (it doesn't include a time zone), and so I can't connect to VM consoles from a client with OpenSSL 1.1.0i (up to date Fedora 27). How can I regenerate these certificates? Also, I noticed they expire next year - is that expiration handled automatically? -- Chris Adams <cma(a)cmadams.net>
