This is a multi-part message in MIME format. --------------AB1791EDE4D5CAFD0D43066B Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hello. I'm running oVirt-Node *4.1.0--0.20170201.0+1* on my hosts and tried a normal upgrade. It detected it has to upgrade to *4.1.1-0.3.rc1.20170303133657.git20d3594.el7.centos* from the ovirt-4.1-pre repository. The upgrade finished with the following problems: ...

So it seems it was not able to do it correctly. This is the second time it happens and I had to remove manually these packages containing 4.1.1 version.

iscsi failover MD3820i
by Marcin Kruk 08 Mar '17

08 Mar '17

Hello I have got Dell MD3820i and four interfaces which was connected to the hostst via switches. But there is only one IP which I can set during the configuration of iSCSI RHV storage. Everything has been fine until I pluged off cable from the storage NIC interface with IP configured in the RHV iSCSI section. Now VDSMD got problem because it tries to connect via iscsiadm with exact IP and does not use the configuration from the /var/lib/iscsi/, where are tree extra paths to achive the LUN. In multipath -ll I see an active path, of course with the second storage interface IP systemctl status vdsmd: CGroup: /system.slice/vdsmd.service ├─4975 /usr/bin/python /usr/share/vdsm/vdsm ├─5558 /usr/bin/sudo -n /usr/sbin/iscsiadm -m node -T iqn.1984-05.com.dell:powervault.md3800i.600a098000ae589c000000005893ade2 -I default -p 192... └─5559 /usr/sbin/iscsiadm -m node -T iqn.1984-05.com.dell:powervault.md3800i.600a098000ae589c000000005893ade2 -I default -p 192.168.130.101 32...

ovirt don't give "initiator name" to cinder when I'm launching a VM with a cinder volume
by herve 08 Mar '17

08 Mar '17

dear ovirt user community, I can't sort out an ovirt issue I got with cinder for weeks, I hope someone could give me a clue... From mi ovirt manager 4.1, I can create and delete a cinder volume or attach and detach a cider vomume from an ovirt VM. The problem is I never had been able to launch an ovirt VM with a cinder volume attached to it. I just got a simple message from ovir web gui: "Failed to run VM centoscinder (User: admin@internal-authz)". what i am using is a RDO newton release of openstack. the backend of cinder is a local lvm, and the openstack VMs can use the cinder volumes from other compute node. from the ovirt 4.1 fedora 24 server: [root@rhevf24 ~]# rpm -qa | grep ovirt-engine-4 ovirt-engine-4.1.0.4-1.fc24.noarch ovirt-engine-setup-plugin-ovirt-engine-4.1.0.4-1.fc24.noarch [root@rhevf24 ~]# from the ovirt server , through the iscsiadm command, I can see for example the 2 disks attached to 2 diffents openstack instances, but not the one I just created from ovirt which is attached to nothing , from the openstack rdo point of view. [root@rhevf24 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.122.36 192.168.122.36:3260,1 iqn.2010-10.org.openstack:volume-f4c6c55c-e383-4781-8d24-d41b55870d29 192.168.122.36:3260,1 iqn.2010-10.org.openstack:volume-58844340-741e-45da-9aa7-b0ed08391df3 as I said previously From ovirt I can create /delete in cinder and attach/detach volumes to ovirt VMs I don't get any troubles with that. ---- in ovirt engine.log almost nothing , except it can't aquire lock.. but in openstack cinder, and with tcpdump I get more informations. tcpdump give me when ovirt intent the iscsi connection something like: json.key == "os-initialize_connection" {. "os-initialize_connection" : {. "connector" : { }, },} and I get from "tail -f /var/log/cinder/volume.log" : 2017-03-07 16:45:06.889 3856 ERROR cinder.volume.targets.iscsi [req-b6d39a14-f9ea-4552-91e7-5db811217b1e dd1dd33789274fb7ba228c75a07c0e94 0f68893965dd4f5dafd319cbffb33bb4 - default default] The volume driver requires the iSCSI initiator name in the connector. ... ... 2017-03-07 16:45:06.891 3856 ERROR oslo_messaging.rpc.server InvalidInput: Invalid input received: Connector doesn't have required information: initiator So it looks like I didn't get or I can't provide the initiator name I want to be connected to. Cinder can't obviously guess which one I want. that's more or less what's the cinder's logs are telling me. I have searched for a long time in internet, it looks like at least since ovirt 3.6, cinder is ont anymore an issue, and can even be integrated with a ceph back end to ovirt... cinder model an client are installed in the ovirt server... Somebody get any clue to tell ma where i made a mistake in the cinder integration with ovirt , which seems to be correct regarding the create/delete attach /detach volume behavior... Thank you Herve

Second node ovirt 4.0 no ovirtmgmt bridge, non-operational issue
by Ian Neilsen 08 Mar '17

08 Mar '17

Hi all I currently have a non-operational second node in my "ovirt 4.0 hosted-engine" installation running on Centos7, kernel 3.10.0-514.10.2.el7.x86_64. When I ran "hosted-engine --deploy" on the second node, it produce the following error(see bottom of email). I now cannot set the second node into operational mode, no matter what I try. I did notice a few things though. #1 - no ovirtmgt bridge was created during hosted-engine deploy; should I create this bridge and retry? #2- vdsmd keep throwing start errors before I ran hosted-engine deploy. I ran vdsm-tool configure --force this seem to fix it. #3 - second node complained of no fencing agent, so I added in a DRAC fence agent and it worked/tested fine. But still not able to go opertional on second node. #4 Ive tried restarting vdsmd, ovirt-ha-agent and ovirt-ha-broker. Both the agent and broker throw error messages.(see bottom of email for errors) Any advice of where to look next, what to fix? ***Hosted-engine --deploy message*** [WARNING] Host left in non-operational state To finish deploying, please: - activate it - restart the hosted-engine high availability services by running on this machine: # service ovirt-ha-agent restart # service ovirt-ha-broker restart [ INFO ] Enabling and starting HA services [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20170307062116.conf' [ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ INFO ] Hosted Engine successfully deployed ***ovirt-ha-agent error message*** ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config ERROR Unable to get vm.conf from OVF_STORE, falling back to initial vm.conf ***ovirt-ha-broker error message*** ovirt-ha-broker ovirt_hosted_engine_ha.broker.notifications.Notifications ERROR Connection unexpectedly closed Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/broker/notifications.py", line 34, in send_email message.as_string()) File "/usr/lib64/python2.7/smtplib.py", line 749, in sendmail self.rset() File "/usr/lib64/python2.7/smtplib.py", line 468, in rsetreturn self.docmd("rset") File "/usr/lib64/python2.7/smtplib.py", line 393, in docmdreturn self.getreply() File "/usr/lib64/python2.7/smtplib.py", line 367, in getreplyraise SMTPServerDisconnected("Connection unexpectedly closed") SMTPServerDisconnected: Connection unexpectedly closed -- Ian Neilsen Mobile: 0424 379 762 Linkedin: http://au.linkedin.com/in/ianneilsen Twitter : ineilsen

oVirt global utilization trend
by Abi Askushi 07 Mar '17

07 Mar '17

Hi, I see that the global utilization 24h trend graph (CPU, RAM, Disk) at dashboard is showing only the last 3 hours. The line for previous hours is flat (see attached). I remember that on a previous installation I had tested it was showing the full 24 hours. Tried to run again engine-setup but issue remains. Any suggestions? Thanx, Alex

Problems adding iSCSI storage domain
by Simon Vincent 07 Mar '17

07 Mar '17

I have setup a small cluster running a hosted engine using iSCSI. I tried to add a new iSCSI storage domain but this failed as not all hosts could access the storage server. I fixed this problem but it now does not let me add the new storage domain as it shows "lun is already part of storage domain". The engine does not show any storage domains but if I look in the database it shows up there. How do I remove this broken storage domain and then re-add it?

3.5->3.6 did not import hosted engine storage domain
by Chris Adams 07 Mar '17

07 Mar '17

So, on to my next upgrade issue (sorry for all the questions and thanks for everybody's help)... I upgraded my test cluster from 3.5 to 3.6 (latest version of each, all on CentOS 7 except the engine on CentOS 6). Now I'm working on the next step, upgrading to 4.0 and migrating the HE to the appliance. When I went from 3.5 to 3.6, I ended up with an fhanswers.conf in the shared storage that only contained "None"; I fixed that based on some mailing list messages (but just mentioning it in case it could be related). My problem is that the hosted engine storage domain did not get imported into the engine DB, so I can't proceed with "hosted-engine --upgrade-appliance". I didn't see any errors, so I'm not sure how that happened. I'm also not sure how to fix that. Suggestions? -- Chris Adams <cma(a)cmadams.net>

Hi, I use 3 nodes with zfs and glusterfs. Are there any suggestions to optimize it? host zfs config 4TB-HDD+250GB-SSD: [root@clei22 ~]# zpool status pool: zclei22 state: ONLINE scan: scrub repaired 0 in 0h0m with 0 errors on Tue Feb 28 14:16:07 2017 config: NAME STATE READ WRITE CKSUM zclei22 ONLINE 0 0 0 HGST_HUS724040ALA640_PN2334PBJ4SV6T1 ONLINE 0 0 0 logs lv_slog ONLINE 0 0 0 cache lv_cache ONLINE 0 0 0 errors: No known data errors Name: GluReplica Volume ID: ee686dfe-203a-4caa-a691-26353460cc48 Volume Type: Replicate (Arbiter) Replica Count: 2 + 1 Number of Bricks: 3 Transport Types: TCP, RDMA Maximum no of snapshots: 256 Capacity: 3.51 TiB total, 190.56 GiB used, 3.33 TiB free

Hi, I implemented a storage domain balancer [1], i.e. a script that tries to keep all storage domains under a defined threshold. We use our oVirt infrastructure for teaching so have several hundreds of users and cca. 800 VMs at this time, so something like this is really needed considering that when students create their VMs they tend to create their disks under the same storage domain (normally the first available one). This results in one or two heavily used SDs and the rest underused. I tried to keep it as simple as possible and doesn't have many features, but it seems to work (I tried it under our conditions: About 10 SDs, relatively highly used). If someone want to improve something on it, pull requests are welcome. Might also be an inspiration on [2]. Regards.

Re: [ovirt-users] [Gluster-users] Hot to force glusterfs to use RDMA?

Dear Deepak, thank you for the hints, which gluster are you using? As you can see from my previous email that the RDMA connection tested with qperf. It is working as expected.

oVirt Nested Virtualization
by Luca 'remix_tj' Lorenzetto 06 Mar '17

06 Mar '17

Hello, we're installing a small ovirt cluster for hosting some test environments at work. We're interested in testing VM running hypervisors (i.e ovirt itself or a small openstack deployment). Is there any documentation showing how to enable nested virtualization in ovirt? I've seen that while adding an host to the cluster there is the opportunity to flag "Nested Virtualization" option, but i didn't understand if other packages and configs are required. Our environment is running latest ovirt 4.1 installed with ovirt-node-ng.

OVF is standard format for describing a VM: https://en.wikipedia.org/wiki/Open_Virtualization_Format All the VM that have a disk on a storage domain are stored in the OVF_STORE disks using OVF format, so you can restore all the VM from storage if you lost your engine database. Or, if you want to move entire storage domain from one setup to another, you can detach the storage domain from one setup, attach to the other setup, and import all the VMs. The OVF is also used by hosted engine to obtain engine vm setup from storage, and start the engine vm after a host is rebooted. > 3. perfect and clear > Thank you > > 2017-03-05 12:32 GMT+01:00 Nir Soffer <nsoffer(a)redhat.com>: >> >> On Sun, Mar 5, 2017 at 10:08 AM, Marcin Kruk <askifyouneed(a)gmail.com> >> wrote: >> > VDSM side, means RHV HOST side, right? >> > I missed LVM tags, so the command: >> > lvs -o vg_name,name,lv_tags is very helpful, thanks. >> > >> > 1.

Ubuntu VM does not complete reboot cycle without Console Open

VMs imported from libvirt have no cdrom device
by Chris Boot 05 Mar '17

05 Mar '17

Hi, I've imported a number of VMs that I previously was running under a self-hosted libvirt configuration. Most of the VMs at the source did not have a cdrom device (but some did) because I just added one as I needed to. Now that the VMs have been imported into oVirt, none of them have a cdrom device. Even booting with the "Attach CD" option doesn't create a cdrom device. I can't see any way to get oVirt to re-create the missing device. Is there a way for me to add these missing devices to my VMs? I'm running oVirt 4.1 on CentOS 7.3.1611 with a hosted engine setup. VMs were migrated from a Debian Stretch machine running libvirt 3.0.0 with qemu 2.8.0. Thanks, Chris -- Chris Boot bootc(a)bootc.net

Question about injecting ISO images workflow and network configuration
by wodel youchi 05 Mar '17

05 Mar '17

Hi, May be it's a silly question :-) , but how are gays configuring the storage network? Let me explain, if the management network and the storage network are not on the same subnet, if you wish to upload and ISO image on an NFS storage domain, you have to have a route between the two subnets, because the VM engine will try to mount the ISO domain locally to inject the file. PS : For iSCSI ISO domain, I don't know how it will be done, I didn't try it. My questions : - why not use the SPM server for that? - Is it safe to merge the management network with the storage network? - Is the best way to do it is to create a route between the the two subnets? Thanks in advance.

Hello there, I am having some trouble when deploying an oVirt 4.1 hosted engine installation. When I m just to end the installation and the hosted engine setup script is about to start the Vm engine (appliance) it fails saying "The VM is not powring up". If I double check the service vdsmd i get this error all the time: vdsm root ERROR failed to retrieve Hosted Engine HA info Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/host/api.py", line 231, in _getHaInfo stats = instance.get_all_stats() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 102, in get_all_stats with broker.connection(self._retries, self._wait): File "/usr/lib64/python2.7/contextlib.py", line 17, in __enter__ return self.gen.next() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/brokerlink.py", line 99, in connection self.connect(retries, wait) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/brokerlink.py", line 78, in connect raise BrokerConnectionError(error_msg) BrokerConnectionError: Failed to connect to broker, the number of errors has exceeded the limit (1) Did anyone have experimented the same problem?¿? Any hint on How to solved it?¿? I have tried several times with clean installations and always getting the same... The host where I am trying to do the installation have CentOS 7... Thanks for all in advance Will be waiting for any hint to see what I am doing wrong... Manuel Luis Aznar

Re: [ovirt-users] best way to remove SAN lun
by Pavel Gashev 05 Mar '17

Please also consider a case when a single iSCSI target has several LUNs and you remove one of them. In this case you should not logout. -----Original Message----- From: <users-bounces(a)ovirt.org> on behalf of Nelson Lameiras <nelson.lameiras(a)lyra-network.com> Date: Friday, 3 March 2017 at 20:55 To: Nir Soffer <nsoffer(a)redhat.com> Cc: users <users(a)ovirt.org> Subject: Re: [ovirt-users] best way to remove SAN lun Hello Nir, I think I was not clear in my explanations, let me try again : we have a oVirt 4.0.5.5 cluster with multiple hosts (centos 7.2). In this cluster, we added a SAN volume (iscsi) a few months ago directly in GUI Later we had to remove a DATA volume (SAN iscsi). Below the steps we have taken : 1- we migrated all disks outside the volume (oVirt) 2- we put volume on maintenance (oVirt) 3- we detach volume (oVirt) 4- we removed/destroyed volume (oVirt) In SAN : 5- we put it offline on SAN 6- we delete it from SAN We thought this would be enough, but later we has a serious incident when log partition went full (partially our fault) : /var/log/messages was continuously logging that it was still trying to reach the SAN volumes (we have since taken care of the issue of log space issue => more aggressive logrotate, etc) The real solution was to add two more steps, using shell in ALL hosts : 4a - logout from SAN : iscsiadm -m node --logout -T iqn.XXXXXXXX 4b - remove iscsi targets : rm -fr /var/lib/iscsi/nodes/iqn.XXXXXXXXX This effectively solved our problem, but was fastidious since we had to do it manually in all hosts (imagine if we had hundreds of hosts...) So my question was : shouldn't it be oVirt job to system "logout" and "remove iscsi targets" automatically when a volume is removed from oVirt ? maybe not, and I'm missing something? cordialement, regards, Nelson LAMEIRAS Ingénieur Systèmes et Réseaux / Systems and Networks engineer Tel: +33 5 32 09 09 70 nelson.lameiras(a)lyra-network.com www.lyra-network.com | www.payzen.eu Lyra Network, 109 rue de l'innovation, 31670 Labège, FRANCE ----- Original Message ----- From: "Nir Soffer" <nsoffer(a)redhat.com> To: "Nelson Lameiras" <nelson.lameiras(a)lyra-network.com> Cc: "Gianluca Cecchi" <gianluca.cecchi(a)gmail.com>, "Adam Litke" <alitke(a)redhat.com>, "users" <users(a)ovirt.org> Sent: Wednesday, February 22, 2017 8:27:26 AM Subject: Re: [ovirt-users] best way to remove SAN lun On Wed, Feb 22, 2017 at 9:03 AM, Nelson Lameiras <nelson.lameiras(a)lyra-network.com> wrote: > Hello, > > Not sure it is the same issue, but we have had a "major" issue recently in our production system when removing a ISCSI volume from oVirt, and then removing it from SAN.

Is there a RFE still waiting to be included on this subject or should I write one ? We have RFE for this here: https://bugzilla.redhat.com/1310330 But you must understand that ovirt does not control your storage server, you are responsible to add devices on the storage server, and remove them. We are only consuming the devices. Even we we provide a way to remove devices on all hosts, you will have to remove the device on the storage server before removing it from hosts. If not, ovirt will find the removed devices again in the next scsi rescan, and we do lot of these to support automatic discovery of new devices or resized devices.

Re: [ovirt-users] rhevm listening on ipv6 ?
by Yevgeny Zaspitsky 05 Mar '17

05 Mar '17

Šimon, According to [1] oVirt should be accessible through IPv6 address. >From my experience engine web&rest can be accessed by using an URL with an IPv6 address in a browser. Please notice that an IPv6 literal address (not a hostname that resolves to an IPv6 address) in a valid URL should be wrapped by brackets, e.g. http:// [1::2]:80/path. You can verify that the engine listens to an IPv6 by running the following command from the Linux console of the host that runs ovirt-engine (while ovirt-engine service runs): netstat -lnp6 | grep <port> where <port> is the port ovirt-engine should be listening to and be accessed through (default is 80). It seems to me like a problem on ManageIQ side. Please let me know if you need further assistance.
