by Punit Dambiwal 27 Jul '14

27 Jul '14

Hi, I have some HA related concern about glusterfs with Ovirt...let say i have 4 storage node with gluster bricks as below :- 1. 10.10.10.1 to 10.10.10.4 with 2 bricks each and i have distributed replicated architecture... 2. Now attached this gluster storge to ovrit-engine with the following mount point 10.10.10.2/vol1 3. In my cluster i have 3 hypervisior hosts (10.10.10.5 to 10.10.10.7) SPM is on 10.10.10.5... 4. What happen if 10.10.10.2 will goes down.....can hypervisior host can still access the storage ?? 5. What happen if SPM goes down ??? Note :- What happen for point 4 &5 ,If storage and Compute both working on the same server. Thanks, Punit

The oVirt team is pleased to announce that the 3.5.0 Second Beta is now available for testing as of Jul 21th 2014. The beta is available now for Fedora 19, Fedora 20 and Red Hat Enterprise Linux 6.5 (or similar). Feel free to join us testing it on Tue Jul 29th second test day! This release of oVirt includes numerous bug fixes. See the release notes [1] for a list of the new features and bugs fixed. The existing repository ovirt-3.5-pre has been updated for delivering this release without the need of enabling any other repository. Please refer to release notes [1] for Installation / Upgrade instructions. New oVirt Live, oVirt Guest Tools and oVirt Node ISO will be available soon as well[2]. Please note that mirrors may need a couple of days before being synchronized. If you want to be sure to use latest rpms and don't want to wait for the mirrors, you can edit /etc/yum.repos.d/ovirt-3.5.repo commenting the mirror line and removing the comment on baseurl line.

Disk migration eats all CPU, vms running in SPM become unresponsive
by Federico Alberto Sayd 25 Jul '14

25 Jul '14

Hello: I am experiencing some troubles with ovirt nodes: When a node is selected as SPM and I move a disk between storage domains, it seems that migration process eats all CPU and some VMs (running on the SPM) hang, others lose network connectivity. The events tab at Ovirt Engine reports the CPU exceeding the defined threshold and then reports that VMs in such host (SPM) are not responding. How can I debug this? Why do the VMs become unresponsive or lost network connectivity when the host CPU goes too high? I have attached a screenshot of the ovirt-engine events, and the relevant engine.log My setup: oVirt Engine Version: 3.4.0-1.el6 (Centos 6.5) Nodes: Centos 6.5 vdsm-4.14.6-0.el6 libvirt-0.10.2-29.el6_5.9 KVM: 0.12.1.2 - 2.415.el6_5.10 (jenkins build) Regards Federico

------=_Part_27854792_967363234.1405525563715 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, We have a production environment with KVM+centos6 and we want to switch to ovirt. At this moment we have 12 VM on three independent server. This VMs uses the local disks of servers, we don't have a central storage. currently we have for ovirt - Two Dell R710 with 128 gigs of ram. - A third dell server for ovirt-engine. - four 1 gb/sec NICs/ server. - Smart GB switch we would like make an ovirt environment with - clusterized, redundant filesystem, data loss protection - If a host goes to down the VMs could made a restart on the remain host - LACP/bonding (mode 6) for fast I/O beetwen gluster hosts, we don't have 10Gbe nics - 8 TB of disk capacity for VMs we don't want: - using hw raid on servers, because we need free disk tray for more capacity My questions. - Which glusterfs method is the best for us for performance? - Can I make a real "performance" disk i/o by 4-4 NICs ? Or I need 10 Gbe nic for this? - How much disk need for good redundancy/performance? 4/server or 2/server ? - What will the weak point our project? Thanks in advance.
