iSCSI Discovery cannot detetect LUN
by Lukáš Kaplan 24 Mar '17

24 Mar '17

Hello all, please do you have some experience with troubleshooting adding of iSCSI domain to ovirt 4.1.1? I am chalenging this issue now: 1) I have successfuly installed oVirt 4.1.1 environment with self-hosted engine, 3 nodes and 3 storages (iSCSI Master domain, iSCSI for hosted engine and NFS ISO domain). Everything is working now. 2) But, when I want to add new iSCSI domain, I can discover it, I can login, but I cant see any LUN on that storage. (I had same problem in oVirt 4.1.0, so I made upgrade to 4.1.1) 3) Then I tryed to add this storage to another oVirt environment (oVirt 3.6) and there are no problem. I can see LUN on that storage and I can connect it to oVirt. I tryed to examine vdsm.log, but it is very detailed and unredable for me :-/ Thak you in advance, have a nice day, -- Lukas Kaplan

Libvirtd Segfault
by Aaron West 24 Mar '17

24 Mar '17

Hi Guys, I've been having some issues this week with my oVirt 4.1 install on CentOS 7... It was previously working great but I made a couple of alterations(which I've mostly backed out now) and I ran a yum update followed by a reboot, however. after it came back up I couldn't start any virtual machines... The oVirt web interface reports : VDSM Local command SpmStatusVDS failed: Heartbeat exceeded VDSM Local command GetStatsVDS failed: Heartbeat exceeded VM My_Workstation is down with error. Exit message: Failed to find the libvirt domain. Plus some other errors so I checked my "dmesg" output and libvirtd seems to segfault : [70835.914607] libvirtd[10091]: segfault at 0 ip 00007f681c7e7721 sp 00007f680c7d2740 error 4 in libvirt.so.0.2000.0[7f681c73a000+353000] Next I checked logs but I couldn't find anything that seemed relevant to me, I mean I see lots of oVirt complaining but that makes sense if libvirtd segfaults right? So last ditch effort was try and use strace and hope with my limited knowlege I spot something uselful but I didn't so I've attahced the strace output to this email in the hope someone else might.

Self-Hosted install on fresh centos 7

Upgrade from 3.6 to 4.1
by Brett Holcomb 24 Mar '17

24 Mar '17

I am currently running oVirt 3.6 on a physical server using hosted engine environment. I have one server since it's a lab setup. The storage is on a Synology 3615xs iSCSI LUN so that's where the vms are. I plan to upgrade to 4.1 and need to check to make sure I understand the procedure. I've read the oVirt 4.1 Release Notes and they leave some questions. First they say I can simply install the 4.1 release repo update all the ovirt-*-setup* and then run engine-setup. 1. I assume this is on the engine VM running on the host physical box. 2. What does engine-setup do. Does it know what I have and simply update or do I have to go through setup again. 3. Then do I go to the host and update all the ovirt stuff? However, they then say for oVirt Hosted Engine follow a link for upgrading which takes me to a Not Found :( page but did have a link back to the release notes which link to the Not Found which.... So what do I need to know about upgrading a hosted engine setup that there are no directions for. Are there some gotchas? I thought that the release notes said I just had to upgrade the engine and then the host. Given that my VMs are on iSCSI what happens if things go bad and I have to start from scratch. Can I import the VMs created under 3.6 into 4.1 or do I have to do something else like copy them somewhere for backup. Any other hints and tips are appreciated. Thanks.

You can use oVirt 4.1 with the ovirt-engine-sdk-python package version 3.x, they are backwards compatible. Regards.

strange behavior of ovirt-node ng update
by Sergey Kulikov 23 Mar '17

23 Mar '17

I have one Ovirt Node in my test cluster(others are centos), I'm observing strange behavior of update checker in engine. In options I can see: engine=# select * from vdc_options where option_name='OvirtNodePackageNamesForCheckUpdate'; option_id | option_name | option_value | version -----------+-------------------------------------+----------------------------+--------- 124 | OvirtNodePackageNamesForCheckUpdate | ovirt-node-ng-image-update | general (1 row) so it tries to check for updated version of ovirt-node-ng-image-update, but there is no ovirt-node-ng-image-update package installed inside updated node image, so engine always shows available updates on this node to the same version: > Check for available updates on host XXX was completed successfully with message 'found updates for packages ovirt-node-ng-image-4.1.1-1.el7.centos, ovirt-node-ng-image-update-4.1.1-1.el7.centos'. I saw a bug in bugzilla, that it should be fixed in 4.0 Initially engine was set up as 4.x version, after that updated between releases and finally to 4.1.0, and today to 4.1.1. I saw this behavior on 4.1.0 node and also on 4.1.1, on this page: http://www.ovirt.org/node/4.0/update/ Maybe my OvirtNodePackageNamesForCheckUpdate was changed between releases, but engine-setup left it untouched and i should change it manually? If so, what it should look like? --
