dns vm and ovirt
by Nathanaël Blanchet 16 Mar '18

16 Mar '18

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 blanchet(a)abes.fr

Quick question about oVirt 3.6 and vdsm log in DEBUG mode (apprently by default??)
by Christopher Cox 16 Mar '18

16 Mar '18

We're running oVirt 3.6 on 9 Dell Blades but with just two fairly fat fabrics, one for LAN stuff, ovirtmgmt and one for iSCSI to the storage domains. 15 VM Storage Domains iSCSI has 4 paths going through a 40Gbit i/o blade to switch 115 VMs or thereabouts 9 VLANS, sharing an i/o blade with ovirtmgmt 40Gbit to switch 500+ virtual disks What we are seeing more and more is that if we do an operation like expose a new LUN and configure a new storage domain, that all of the hyervisors go "red triangle" and "Connecting..." and it takes a very long time (all day) to straighten out. My guess is that there's too much to look at vdsm wise and so it's waiting a short(er) period of time for a completed response than what vdsm is going to us, and it just cycles over and over until it just happens to work. I'm thinking that vdsm having DEBUG enabled isn't helping the latency, but as far as I know it came this way be default. Can we safely disable DEBUG on the hypervisor hosts for vdsm? Can we do this while things are roughly in a steady state? Remember, just doing the moves could throw everything into vdsm la-la-land (actually, that might not be true, might take a new storage thing to do that). Just thinking out loud... can we safely turn off DEBUG logging on the vdsms? Can we do this "live" through bouncing of the vdsm if everything is "steady state"? Do you think this might help the problems we're having with storage operations? (I can see all the blades logging in iSCSI wise, but ovirt engine does the whole red triangle connecting thing, for many, many, many hours). Thanks, Christopher

Re: [ovirt-users] Using VDSM to edit management interface
by Kirin van der Veer 16 Mar '18

16 Mar '18

Ďakujem Peter, but this doesn't seem to work in my case. /etc/resolv.conf is regenerated by Network Manager after a reboot and my domain settings are lost. Your comments regarding the reliance on DNS make sense for most installations, but in my case oVirt is a secondary service that I would not expect to run unless our core infrastructure is working correctly. I'm hesitant to edit /etc/hosts directly, since that can lead to confusion when the underlying IP addresses change. For now I will hardcode the IPs of my servers. It's frustrating (and surprising) that there is not an easy way to do this. Kirin.

ovirt 4.2.2-rc3 switching from legacy to OVS..
by Thomas Davis 15 Mar '18

15 Mar '18

I'm getting further along with 4.2.2rc3 than the 4.2.1 when it comes to hosted engine and vlans.. it actually does install under 4.2.2rc3. But it's a complete failure when I switch the cluster from Linux Bridge/Legacy to OVS. The first time I try, vdsm does not properly configure the node, it's all messed up. I'm getting this in vdsmd logs: 2018-03-08 23:12:46,610-0800 INFO (jsonrpc/7) [api.network] START setupNetworks(networks={u'ovirtmgmt': {u'ipv6autoconf': True, u'nic': u'eno1', u'vlan': u'50', u'ipaddr': u'192.168.85.49', u'switch': u'ovs', u'mtu': 1500, u'netmask': u'255.255.252.0', u'dhcpv6': False, u'STP': u'no', u'bridged': u'true', u'gateway': u'192.168.85.254', u'defaultRoute': True}}, bondings={}, options={u'connectivityCheck': u'true', u'connectivityTimeout': 120}) from=::ffff:192.168.85.24,56806, flow_id=4147e25f-0a23-4f47-a0a4-d424a3437d11 (api:46) 2018-03-08 23:12:52,449-0800 INFO (jsonrpc/2) [jsonrpc.JsonRpcServer] RPC call Host.ping2 succeeded in 0.00 seconds (__init__:573) 2018-03-08 23:12:52,511-0800 INFO (jsonrpc/7) [api.network] FINISH setupNetworks error=[Errno 19] ovirtmgmt is not present in the system from=::ffff:192.168.85.24,56806, flow_id=4147e25f-0a23-4f47-a0a4-d424a3437d11 (api:50) 2018-03-08 23:12:52,512-0800 ERROR (jsonrpc/7) [jsonrpc.JsonRpcServer] Internal server error (__init__:611) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 606, in _handle_request res = method(**params) File "/usr/lib/python2.7/site-packages/vdsm/rpc/Bridge.py", line 201, in _dynamicMethod result = fn(*methodArgs) File "<string>", line 2, in setupNetworks File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 48, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/API.py", line 1527, in setupNetworks supervdsm.getProxy().setupNetworks(networks, bondings, options) File "/usr/lib/python2.7/site-packages/vdsm/common/supervdsm.py", line 55, in __call__ return callMethod() File "/usr/lib/python2.7/site-packages/vdsm/common/supervdsm.py", line 53, in <lambda> **kwargs) File "<string>", line 2, in setupNetworks File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod raise convert_to_error(kind, result) IOError: [Errno 19] ovirtmgmt is not present in the system 2018-03-08 23:12:52,512-0800 INFO (jsonrpc/7) [jsonrpc.JsonRpcServer] RPC call Host.setupNetworks failed (error -32603) in 5.90 seconds (__init__:573) 2018-03-08 23:12:54,769-0800 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call Host.ping2 succeeded in 0.00 seconds (__init__:573) 2018-03-08 23:12:54,772-0800 INFO (jsonrpc/5) [api.host] START getCapabilities() from=::1,45562 (api:46) 2018-03-08 23:12:54,906-0800 INFO (jsonrpc/5) [api.host] FINISH getCapabilities error=[Errno 19] ovirtmgmt is not present in the system from=::1,45562 (api:50) 2018-03-08 23:12:54,906-0800 ERROR (jsonrpc/5) [jsonrpc.JsonRpcServer] Internal server error (__init__:611) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 606, in _handle_request res = method(**params) File "/usr/lib/python2.7/site-packages/vdsm/rpc/Bridge.py", line 201, in _dynamicMethod result = fn(*methodArgs) File "<string>", line 2, in getCapabilities File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 48, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/API.py", line 1339, in getCapabilities c = caps.get() File "/usr/lib/python2.7/site-packages/vdsm/host/caps.py", line 168, in get net_caps = supervdsm.getProxy().network_caps() File "/usr/lib/python2.7/site-packages/vdsm/common/supervdsm.py", line 55, in __call__ return callMethod() File "/usr/lib/python2.7/site-packages/vdsm/common/supervdsm.py", line 53, in <lambda> **kwargs) File "<string>", line 2, in network_caps File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod raise convert_to_error(kind, result) IOError: [Errno 19] ovirtmgmt is not present in the system So something is dreadfully wrong with the bridge to ovs conversion in 4.2.2rc3. thomas

Host can not boot any more with current kernel
by Jonathan Baecker 15 Mar '18

15 Mar '18

Hello everybody, Today I update my engine, from 4.2.1.6 to 4.2.1.7 and later I update two hosts. All are running on CentOS 7.4 Now they have the kernel 3.10.0-693.21, one host I can start normal and the other one always reboot short after the menu where I can select the kernel. There is not even an error message and I can not switch to the boot log screen. The same behavior I have with kernel 3.10.0-693.17. Kernel *.11 and older are working. Have any body experience this issue and know what to do? Regards Jonathan
