[ovirt-users] ovirt node pxe and thinpool errror in status
Hello, I'm experimenting to install ovirt ng node 4.2 via pxe and it seems all went ok. Only problem I have is that opening terminal session I get this traceback that seems related to thinpool Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/nodectl/__main__.py", line 42, in CliApplication() File "/usr/lib/python2.7/site-packages/nodectl/__init__.py", line 200, in CliApplication return cmdmap.command(args) File "/usr/lib/python2.7/site-packages/nodectl/__init__.py", line 118, in command return self.commands[command](**kwargs) File "/usr/lib/python2.7/site-packages/nodectl/__init__.py", line 101, in motd Motd(Status(Health(self.imgbased).status(), File "/usr/lib/python2.7/site-packages/imgbased/plugins/core.py", line 358, in status status.results.append(group().run()) File "/usr/lib/python2.7/site-packages/imgbased/plugins/core.py", line 385, in check_thin pool = self.app.imgbase._thinpool() File "/usr/lib/python2.7/site-packages/imgbased/imgbase.py", line 120, in _thinpool return LVM.Thinpool.from_tag(self.thinpool_tag) File "/usr/lib/python2.7/site-packages/imgbased/lvm.py", line 191, in from_tag assert len(lvs) == 1 AssertionError Admin Console: https://192.168.122.196:9090/ [root@localhost ~]# Current disk layout is [root@localhost ~]# fdisk -l /dev/vda Disk /dev/vda: 53.7 GB, 53687091200 bytes, 104857600 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000a3595 Device Boot Start End Blocks Id System /dev/vda1 *2048 2099199 1048576 83 Linux /dev/vda2 2099200 10485759951379200 8e Linux LVM [root@localhost ~]# pvs PV VG Fmt Attr PSize PFree /dev/vda2 centos lvm2 a-- <49.00g 9.80g [root@localhost ~]# vgs VG #PV #LV #SN Attr VSize VFree centos 1 3 0 wz--n- <49.00g 9.80g [root@localhost ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert pool00 centos twi-aotz-- <34.16g 10.28 9.18 root centos Vwi-aotz-- <34.16g pool00 10.28 swap centos -wi-ao 5.00g [root@localhost ~]# Any hint?

So it means that people who thought about hosted engine feature didn't get into your philosophy of running the engine into a second datacenter Again, strictly a "risk" thing. Hosted engine is by definition a "chicken and egg" thing. It's great for learning and for lab... but if you're going to run production, I'd at least consider the latter option I presented. With that said, we run dedicated engines today, not hosted. Remember, ovirt nodes run even while the engine is down. So you can tolerate an engine outage for a time period, just can't have reliability in case of node failures, etc. So for us, most of the risk is in rebuilding a new engine if we have to... but certainly considered a "rare" case. Putting key infrastructure inside the very thing that needs the key infrastructure to run is just fraught with problems. Everything has costs and typically, the more robust/reliable your setup, the more it's going to cost. I just wanted to present an "in between" style setup that gives you more reliability, but perhaps not the "best", while keeping costs way down. To me, if you're running any datacenter cluster (for example), you need to have a minimum of 3 nodes. People might not like that, but it's my minimum for reliability and flexibility. So... if wanted to use VMs for core infrastructure, that's 3 nodes. That core infrastructure datacenter might have a hosted engine, but likely also has "static definitions". It's part of the "core", at least several parts of it are. But the idea is it could hold: DNS, DHCP, Active Directory/LDAP, files shares (even storage domains for other datacenters), etc. Obviously a "core" failure is a "core" failure and thus needs the same treatment as whatever you consider to be "core" today. (thus on total "outage" bring up, you bring up the core, which now includes this core infrastructure datacenter... your core "tests" are run to verify, and then the rest is brought up) Then each general production datacenter cluster would have 3 nodes with the engine(s) being a VM(s) off the infrastructure datacenter using core infrastructure off that infrastructure datacenter as well. Again, this is very much like most cloud service providers today. Again, just ideas, mainly thinking on the "cheap", though some might not think so (you'll just have to trust me, what I'm presenting here is incredibly cheap for the reliability and flexibility it provides). Just my opinion. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[ovirt-users] Trunk'd Network
Community, I am trying to trunk two VLAN's to a VM on OVIRT 4.2 and all the research/docs I have seen is to create a standard VM network and to NOT tag anything. That is "Supposed" to pass all traffic where the attached VM will need to tag said traffic. Everything I have tried has been unsuccessful and I am not seeing any traffic pass to the VM. Has anyone successfully accomplished sending mulitple VLAN's downstream (vswitch) to a VM? On the VMWARE side the 4095 VLAN would accomplish this and I can do so in my VMWARE test lab. thanks Andy ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[ovirt-users] dns vm and ovirt
Hi all, I'd need some piece of good practice about dealing a DNS server in or out of ovirt. Until now we never wanted to integrate the DNS vm into ovirt because of the strong dependency. if the DNS server fails for any reason, it becomes difficult ot join the webadmin (except with a static etc hosts) and the nodes may become unvailable if they had been configured with fqdn. We could consider a DNS failover setup, but in a self hosted engine setup (and more globally an hyperconverged setup) , it doesn't make sense of setting up a stand alone DNS vm outside of ovirt. So what about imitating engine vm status in a hosted engine setup? Is there a way to install the DNS vm outside of ovirt but on the ovirt host (and why not in a HA mode)? Second option could be installing the named service on the hosted engine vm? Any suggestion or return of experience would be much appreciated. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanc...@abes.fr ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hi, In case of a total failure of the hosted engine VM, it is recommended to recreate a new one and restore a backup. I hope it works, I will probably have to do this very soon.

Something like identifying VMs and their snapshots in the subdirectories, and the guess what is linked to what, ... ?I have a few machines but if I have to rebuild all the engine setup and content, I would like to be able to identify resources easily. A few times ago, I was doing some experiments with XenServer and destroyed/recreated some setup items : I ended with a lot of oprhan resources, and it was a mess to reattach snapshots to their respective VMs. So if oVirt is more helpful in that way ...

[ovirt-users] Failed to synchronize networks of Provider ovirt-provider-ovn
Hi, After upgrading to 4.2.1 I have problems with ovn provider. I'm getting "Failed to synchronize networks of Provider ovirt-provider-ovn." I use custom SSL certificate in apache and I guess this is the reason. I've tried to update ovirt-provider-ovn.conf with [OVIRT] #ovirt-ca-file=/etc/pki/ovirt-engine/ca.pem ovirt-ca-file=/etc/pki/ovirt-engine/apache-ca.pem but still no go Any tips on this? thanks G ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] NFS 4.1 support and migration
As I thought, the GUI didn't allow me to put the domain she depends on in maintenance, so the engine domain wil stay in v3 for now. Maybe I should delete the engine vm, recreate it with new NFS options and then restore the last backup ? I may try this later. For the other domains, auto negociation of NFS settings worked and they are now all mounted using 4.1 version.
