How do I activate a hot-plugged disk (in v3 Python SDK) ?
by Yaniv Kaul 26 Jul '16

26 Jul '16

After successfully attaching a disk and verifying its status is in 'ok', I've tried: api.vms.get(VM0_NAME).disks.get(DISK1_NAME).set_active(True) But it doesn't really activate it. What's the correct way to activate it? (It works well via the UI). TIA, Y.

Hosted Engine & FC Data Domain

This is a multi-part message in MIME format. --------------2602CBAB068A90C4C57253F3 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello, I had recently installed oVirt 4.0.1 Hosted Engine with FC (SAN) Storage. I could install the oVirt, deploy hosted-engine. But when I accessed the Engine Web Admin, I noticed the following: a. There was no Data Domain. I had to import the FC LUN, on which the Hosted Engine's Disk resided into Storage manually. But when I attempted to attach the data domain to Data Center, it failed. b. I ended up removing all configuration, and recreated the FC LUNs. This time, I created two LUNs, on one LUN, the Hosted Engine resided. This time, first, I had to import the second LUN as master Data Domain and add the LUN on which Engine VM resided as just another Data Domain. Now the questions: i. Will Hosted Engine not automatically import the hosted_storage as master data domain? Why does it throw error when attempted to import and attach to DC? ii. Is it necessary to have another data domain as master data domain, before attaching hosted_storage? iii. How do we change the master data domain from one to another? -- Thanks & Regards, Anantha Raghava --------------2602CBAB068A90C4C57253F3 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hello, I had recently installed oVirt 4.0.1 Hosted Engine with FC (SAN) Storage.

oVirt 4 master storage down - unable to activate after power loss
by Robin Vanderveken 25 Jul '16

25 Jul '16

Dear oVirt users I've been having several problems with my oVirt nodes utilising GlusterFS after simulating a power loss. Our testing setup for oVirt consists of 3 nodes, 2 with GlusterFS storage and 1 just for computing. Everything seems to be setup correct and was working correctly. Then after simulating a power loss the master storage goes down, and therefore the VMs and data center go down as well. I checked the GlusterFS configuration and it seems to be correct (see attachment). I checked the oVirt configuration and it seems to be correct (see attachment). I tried putting several Nodes in Maintenace several times, even putting in maintenance and reinstalling them. Only when putting the nodes in maintenance (and choosing to stop the GlusterFS service) triggers Contending on the other Nodes. Only then there is a chance that a Node goes from Contending to SPM, which does not always happen. After trying this several times I got a main Node to become SPM, but the master storage remains down. When I select the master storage, go in the Data center, select the data center and click Activate, then both the master storage and the data center go in the state Locked for a few seconds and then Inactive again. Then I upgraded to oVirt 4 (oVirt Engine Version: 4.0.0.6-1.el7.centos) and tried everything again, resulting in the same result. I searched online and found this mailing list which is very similar: http://lists.ovirt.org/pipermail/users/2014-August/026905.html . Unfortunately the solution was not posted/mailed. I also found this: https://www.mail-archive.com/users@ovirt.org/msg08105.html suggesting the kernel version is not correct, but I am unsure how to check this. In the attachment I added relevant logs: - GlusterFS service on both main nodes - /var/log/vdsm/vdsm.log , /var/log/vdsm/supervdsm.log , /var/log/messages , /var/log/sanlock.log , /var/log/ovirt-engine/engine.log-20160725.gz , /var/log/ovirt-engine/engine.log of the oVirt engine as attachments (I clicked on Activate on the data center at 9:45:30 am GMT). It can be possible that I need to send different engine logs, please tell me if necessary. Any help would be highly appreciated.

Blog post: Monitoring Improvements in oVirt
by Arik Hadas 25 Jul '16

25 Jul '16

Hi all, I wrote a blog post that summarizes the recent improvements in the code that monitors virtual machines in oVirt. It describes the changes that were done and shows a comparison of different aspects of oVirt with these changes (based on the master branch) vs oVirt 3.6 without these changes: http://ahadas.github.io/monitoring-improvements-in-ovirt/ It is mostly a technical post. However, users might find it interesting as well. Note that the measurements were taken on an environment with 1 host and 6000 running VMs (in a pool). Each VM had a network interface and was diskless. Obviously, this is not a typical setup but it was useful to easily expose some of weak sides of the monitoring. Your feedback is always welcome! Regards, Arik
