High latency events and events history settings
by Gianluca Cecchi 05 Jun '18

05 Jun '18

Hello, I'm going to debug some spot events I have in my iSCSI connection frm hypervisors. Sometimes I get May 31, 2018, 7:14:51 AM Storage domain ovsd3750 experienced a high latency of 8.96043 seconds from host ov200. This may cause performance and functional issues. Please consult your Storage Administrator. Jun 1, 2018, 5:26:25 AM Storage domain ovsd3750 experienced a high latency of 8.26526 seconds from host ov301. This may cause performance and functional issues. Please consult your Storage Administrator. Jun 2, 2018, 5:21:37 AM VDSM ov200 command SpmStatusVDS failed: (-202, 'Sanlock resource read failure', 'IO timeout') --> it seems no impact, actually, after a few seconds it becomes again SPM Jun 3, 2018, 7:00:14 AM Storage domain ovsd3750 experienced a high latency of 6.37818 seconds from host ov300. This may cause performance and functional issues. Please consult your Storage Administrator. And yesterday a VM running on ov301 node gets paused for a few seconds. Jun 4, 2018, 7:02:26 AM VM dbatest3 has been paused. Jun 4, 2018, 7:02:26 AM VM dbatest3 has been paused due to storage I/O problem. Jun 4, 2018, 7:02:40 AM VM dbatest3 has recovered from paused back to up. Some questions: - I'm investigating with the users, but in case it is indeed this VM causing problems on storage latency, what are my best chance to avoid it? To change disk profile for the disks of this particular VM? Or is there anything I can do globally? Or any settings on storage domain itself? What best practice? Is there a default sort of top I/O consuming barrier pre-defined on storage access speed from VMs? - How many days is the default history for events and how I can see it from web admin gui or other means? Can I change this dwfault and how? It seems I only see this possibly related parameter with engine-config command: EventProcessingPoolSize (with the value of 10 at this time) ? Any pointer to configure events' history retained settings? Thanks in advance, Gianluca

Microsoft Network Load Balancing
by Matthew Southwick 05 Jun '18

05 Jun '18

Any help appreciated. I have tried any and all combinations of network filters, custom network settings on vNIC, custom "macspoof" settings on the VM's. I have read countless blogs and examples. Could anyone please give me a simple list of items to check/change so that I can get windows network load balancing working between to VM's? At present, I have a network vNIC profile set to "No Network Filter" I have no custom properties on the virtual machines. I have no Network Filter Parameters set on the virtual machine vNIC.

oVirt: single host install

Use case: small sites with a minimum number of vm's. Is there such a thing as a single host install? Is it valid for production use? What kind of storage?

How to increase the total space of storage domain
by Pym 04 Jun '18

04 Jun '18

Hi: In the management page of the web, the total space of the domain added to the storage domain page cannot specify a specific value. The total space value is determined by a specific code function based on the configuration parameters of the physical machine, or is it a fixed value？ Is there any way to modify this value? After I create multiple virtual machines, this space is not enough to continue to create virtual machines. How can I solve this problem? Thank you.

What are the steps to upgrade the 4.1 to 4.2?
by Arman Khalatyan 04 Jun '18

Hello everybody, I wondered if one could first upgrade the engine machine before upgrading the hosts. Is the engine 4.2.x is backwards compatible with 4.1.x? Thanks, Arman.
