[ovirt-users] New Stats for oVirt Community
The folks at Bitergia have been working on improving the community metrics dashboard located at ovirt.org/stats. I was just notified that, per our request, metrics for a big asset in our community--the #ovirt IRC--have been added to the dashboard. Swing by the page and see who's active on IRC and in the rest of the oVirt community!

I am setting up a 2 Node Cluster with GlusterFS Sync Replication. I was about to buy a 2-Port Intel Gbit nic for each host which is about 150Eur each. However, for a little extra of 180Eur you get a 10GBit Infiniband - MCX311A-XCAT. I would like to have quick opinions on this. Should i pay a little more and then get 10MBit instead of 2GBit bonded? Infiniband is good for GlusterFS / storage connection but never never never never ever use it as a vm network - believe me it's a nightmare. So you would direct connect your 2 nodes as otherwise you would have to buy an Infiniband switch as well (btw I'm not sure if direct connect is possible, but I guess it is). Keep in mind that Infiniband cables aren't cheap, too. Why don't you go for 10Gbit/s Ethernet? Welcome to Ovirt. We are on infiniband IPoIB for about 3 years now (started with VMWare). So we jumped on the 10GBit path long before 10GB ethernet had reasonable prices. We are fine with it but you should consider the following aspects. - Go for ConnectX-2 cards or higher. They allow for IPoIB TCP offloading. Do not believe the other information you will find on the internet. A helful statment here: http://permalink.gmane.org/gmane.linux.drivers.rdma/18032 - With IPoIB infiniband you should always be happy to achieve more than 1GBit throughput. A hear a lot of people complaining that they do not get wire speed. The stack is quite complex and from our experience we can reach 5-7GBit speeds easily on a DDR backbone (16 Gbps payload). Better CPUs will increase the throughput. A jump from Xeon 5400 to 5600 gave a nice boost. - Everything around NFS over RDMA is currently a mess. - Cable prices are a real pain (at least in Europe). - Older CX4 Switches are very cheap and rock solid. We have a CISCO 7000D. Though limited to 2044MTU they are fine. - Infiniband requires a subnet manager on the network. Cards will only get a link if that process is available. Either you need a switch with an builtin SM or in case of direct connection it must run on one of the hosts. - always remember that GBit bonding will not improve the throughput of one connection. So you can easily migrate a single VM or disks over infiniband with much more than 1GBit while an ethernet bond will be limited to 1Gbit. Maybe you should have a look at the 10GBit mellanox ethernet adapters. They are floating around for cheap prices ~$60 have a SFP+ port and are build from the same silicone as the infiniband cards. For direct connections they should be fine but switching hardware is expensive. Markus Diese E-Mail enthält vertrauliche und/oder rechtlich geschützte Informationen.

[ovirt-users] Recommended setup for a FC based storage domain
Hi, I have a 4 node cluster setup and my storage options right now are a FC based storage, one partition per node on a local drive (~200GB each) and a NFS based NAS device. I want to setup export and ISO domain on the NAS and there are no issues or questions regarding those two. I wasn't aware of any other options at the time for utilizing a local storage (since this is a shared based datacenter) so I exported a directory from each partition via NFS and it works. But I am little in the dark with the following: 1. Are there any advantages for switching from NFS based local storage to a Gluster based domain with blocks for each partition. I guess it can be only performance wise but maybe I'm wrong. If there are advantages, are there any tips regarding xfs mount options etc ? 2. I've created a volume on the FC based storage and exported it to all of the nodes in the cluster on the storage itself. I've configured multipathing correctly and added an alias for the wwid of the LUN so I can distinct this one and any other future volumes more easily. At first I created a partition on it but since oVirt saw only the whole LUN as raw device I erased it before adding it as the FC master storage domain. I've imported a few VM's and point them to the FC storage domain. This setup works, but: - All of the nodes see a device with the alias for the wwid of the volume, but only the node wich is currently the SPM for the cluster can see logical volumes inside. Also when I setup the high availability for VM's residing on the FC storage and select to start on any node on the cluster, they always start on the SPM. Can multiple nodes run different VM's on the same FC storage at the same time (logical thing would be that they can, but I wanted to be sure first). I am not familiar with the logic oVirt utilizes that locks the vm's logical volume to prevent corruption. - Fdisk shows that logical volumes on the LUN of the FC volume are missaligned (partition doesn't end on cylindar boundary), so I wonder if this is becuase I imported the VM's with disks that were created on local storage before and that any _new_ VM's with disks on the fc storage would be propperly aligned. This is a new setup with oVirt 3.4 (did an export of all the VM's on 3.3 and after a fresh installation of the 3.4 imported them back again). I have room to experiment a little with 2 of the 4 nodes because currently they are free from running any VM's, but I have limited room for anything else that would cause an unplanned downtime for four virtual machines running on the other two nodes on the cluster (currently highly available and their drives are on the FC storage domain). All in all I have 12 VM's running and I'm asking on the list for advice and guidance before I make any changes. Just trying to find as much info regarding all of this as possible before acting upon.

Even when the VMs are marked as HA, if the gluster storage goes down for a few seconds the VMs go to a paused state and can never be resumed. They require a hard reset.
