Where to configure iscsi initiator name?
by Dan Poltawski 21 Aug '19

21 Aug '19

When I added the first node a 'random' initiator name was generated of form: # cat /etc/iscsi/initiatorname.iscsi InitiatorName=iqn.1994-05.com.redhat:[RANDOM] Having attempted to add another node, this node has another initiator name generated and can't access the storage. Is there a way to configure this initiator name to a static value which will be configured when new nodes get added to the cluster? Or is there some reason for this i'm missing? thanks, Dan ________________________________ The Networking People (TNP) Limited. Registered office: Network House, Caton Rd, Lancaster, LA1 3PE.

Hyperconverged setup ovirt 4.3.x using ansible?
by adrianquintero＠gmail.com 20 Aug '19

20 Aug '19

Hi, I am trying to do a Hyperconverged setup using ansible. So far I have been able to run a playbook to setup gluster but have not been able to identify how to install the Hosted-Engine VM using ansible and tie all the pieces together. Can someone point me in the right direction to deploy a hyperconverged environment using ansible? I have succesfully deployed ovirt 4.3.5 (Hyperconverged) using the web UI. thanks.

numa pinning for high performance
by Vincent Royer 20 Aug '19

20 Aug '19

Is there a good place to learn about cpu pinning and the various settings? I've built a test VM and am trying to understand - I've given it 2 cpus, 4 cores each, 1 thread per core. - The VM is pinned to a specific host with passthrough cpu enabled - numa pinning, first 4 cores on physical socket 1 and the next 4 on physical socket 2 - The host has two sockets each with 20 core cpus I would expect to see a load applied on 8 of the 40 cores on the host during testing. Instead it seems like 32 of 40 cores are working at 100%. What are the effects of this on the performance of the vm?

Hi. We are running oVirt 4.3.4 with each of the hosts configured to use local storage.

Issues with oVirt-Engine start - oVirt 4.3.4
by Vrgotic, Marko 19 Aug '19

19 Aug '19

Dear oVirt, While working on a procedure to get the NFS v4 mount from Netapp, working on oVIrt, following steps came out to be the way to go in regards of setting it up for oVIrt SHE and VM Guests: * mkdir /mnt/rhevstore * mount -t nfs 10.20.30.40:/ovirt_hosted_engine /mnt/rhevstore * chown -R 36.36 /mnt/rhevstore * chmod -R 755 /mnt/rhevstore * umount /mnt/rhevstore This works fine, and it needs to be executed on each Hypervisor, before its provisioned into oVirt. However, just today I have discovered that command chmod -R 755 /mnt/rhevstore, if executed on new to be added Hypervisor, after oVirt is already running, it brings the oVirt Engine into broken state. The moment I executed the above on 3rd Hypervisor, before provisioning it into oVirt, following occurred: * Engine threw following error: * 2019-08-19 13:16:31,425Z ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.SpmStatusVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-82) [] Failed in 'SpmStatusVDS' method * Connection was lost: * packet_write_wait: Connection to 10.210.11.10 port 22: Broken pipe * And VDSM on SHE Hosting hypervisor started logging errors like: * 2019-08-19 15:00:52,340+0000 INFO (jsonrpc/0) [jsonrpc.JsonRpcServer] RPC call Host.getAllVmStats succeeded in 0.00 seconds (__init__:312) * 2019-08-19 15:00:53,865+0000 WARN (vdsm.Scheduler) [Executor] Worker blocked: <Worker name=periodic/2 running <Task <Operation action=<vdsm.virt.sampling.HostMonitor object at 0x7f59442c3d50> at 0x7f59442c3b90> timeout=15, duration=225.00 at 0x7f592476df90> task#=578 at 0x7f59442ef910>, traceback: * File: "/usr/lib64/python2.7/threading.py", line 785, in __bootstrap * self.__bootstrap_inner() * File: "/usr/lib64/python2.7/threading.py", line 812, in __bootstrap_inner * self.run() * File: "/usr/lib64/python2.7/threading.py", line 765, in run * self.__target(*self.__args, **self.__kwargs) * File: "/usr/lib/python2.7/site-packages/vdsm/common/concurrent.py", line 195, in run * ret = func(*args, **kwargs) * File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 301, in _run * self._execute_task() * File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 315, in _execute_task * task() * File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 391, in __call__ * self._callable() * File: "/usr/lib/python2.7/site-packages/vdsm/virt/periodic.py", line 186, in __call__ * self._func() * File: "/usr/lib/python2.7/site-packages/vdsm/virt/sampling.py", line 481, in __call__ * stats = hostapi.get_stats(self._cif, self._samples.stats()) * File: "/usr/lib/python2.7/site-packages/vdsm/host/api.py", line 79, in get_stats * ret['haStats'] = _getHaInfo() * File: "/usr/lib/python2.7/site-packages/vdsm/host/api.py", line 177, in _getHaInfo * stats = instance.get_all_stats() * File: "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 94, in get_all_stats * stats = broker.get_stats_from_storage() * File: "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/brokerlink.py", line 143, in get_stats_from_storage * result = self._proxy.get_stats() * File: "/usr/lib64/python2.7/xmlrpclib.py", line 1233, in __call__ * return self.__send(self.__name, args) * File: "/usr/lib64/python2.7/xmlrpclib.py", line 1591, in __request * verbose=self.__verbose * File: "/usr/lib64/python2.7/xmlrpclib.py", line 1273, in request * return self.single_request(host, handler, request_body, verbose) * File: "/usr/lib64/python2.7/xmlrpclib.py", line 1303, in single_request * response = h.getresponse(buffering=True) * File: "/usr/lib64/python2.7/httplib.py", line 1113, in getresponse * response.begin() * File: "/usr/lib64/python2.7/httplib.py", line 444, in begin * version, status, reason = self._read_status() * File: "/usr/lib64/python2.7/httplib.py", line 400, in _read_status * line = self.fp.readline(_MAXLINE + 1) * File: "/usr/lib64/python2.7/socket.py", line 476, in readline * data = self._sock.recv(self._rbufsize) (executor:363) * 2019-08-19 15:00:54,103+0000 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call Host.ping2 succeeded in 0.00 seconds (__init__:312) I am unable to boot the Engine VM – it end up in Status ForceStop Hosted-engine –vm-status shows: [root@ovirt-sj-02 ~]# hosted-engine --vm-status The hosted engine configuration has not been retrieved from shared storage.

Hosted Engine on seperate L2 network from nodes?
by Dan Poltawski 19 Aug '19

19 Aug '19

For some security requirements, I’ve been asked if it’s possible to segregate the hosted engine from the physical nodes, with specific firewalling for access to do node/ storage operations (I’m using managed block storage). Is this an approach others us, or is it better practice and just ensure the nodes and engine are all sharing the same network?
