[Users] Moving hosts to new Gluster cluster issues
by Pat Pierson 12 Dec '13

12 Dec '13

I am in the process of upgrading my cluster while at the same time moving to gluster. My engine is version 3.3.1 and I have a NFS cluster running in 3.1 compatibility mode that I am moving to a 3.3 GlusterFS cluster. Host3 runs the engine and is on the NFS cluster while host2 is running a single brick gluster volume and a few vms on the Gluster cluster. Host1 is the machine I am trying to move from the NFS cluster to the Gluster cluster. Host1 is upgraded to the latest vdsm/gluster/etc (done via the host re-install option in the UI while in maintenance mode). I attempt to change the datacenter/cluster on the host edit page and after I press OK I get the following error in the UI: "Error while executing action ChangeVDSCluster: Network error during communication with the Host." I have checked all IPs and DNS resolutions and even went so far to disable iptables on all of the hosts to make sure I don't have any firewall issues. Host1/2 is running latest centos 6.5 and Host3 is slightly behind on centos 6.4. While attempting to make the change I have tailed the engine.log and it is in the following pastebin http://pastebin.com/1yaK4vYt. Any help would be great. I just need a direction to look in. -- Patrick Pierson

[Users] Virtio NIC in Windows failing at boot
by Allen Belletti 12 Dec '13

--_000_97c686f412944d9f80995124b7d7f9b7BN1PR04MB170namprd04pro_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi All, Ever since moving from oVirt 3.1 (with Fedora image-based nodes) to oVirt 3= .3 (and now 3.3.1) with CentOS 6.4 (now 6.5) nodes, I've been having a seri= ous problem with our Windows guests. To my knowledge, none of the Linux gu= ests have ever been affected. The problem appears when a Windows guest is rebooted. Occasionally this ha= ppens during maintenance work but more often as a result of Microsoft updat= es which require a reboot. The most recent batch of these that we allowed = resulted in something like 35 of 40 Windows guests losing networking. What we see is that the VirtIO Ethernet Adapter is enabled but shows no evi= dence of actually being connected to the network. The MAC never appears in= our switches, etc. The solution is to connect to the guest via console an= d manually disable, then enable, the NIC. Problem solved. I've found at least two other references to this issue: http://forum.proxmox.com/threads/11160-Windows-2008-R2-Server-Standard-Edit= ion-VIRTIO-NIC-Drivers-dont-work-on-boot (exactly our issue) http://forum.proxmox.com/threads/16550-Windows-server-2012-blue-screen-virt= io-win-ethernet-card (similar, though we never see a crash) Needless to say, this is super annoying. Right now it seems my options see= m to be: 1. Implement a script to reset the NIC as suggested in the first link. 2. Revert to e1000 but not sure how much that will hurt performance and/or= whether it will limit us to 1 Gbps throughput. Has anyone experienced this? Would I likely have better luck on the VirtIO= list? We've been running VirtIO Ethernet 61.63.103.3000 from virtio-win-0= .1-65.iso but I just now found 61.65.104.7400 included in virtio-win-0.1-74= .iso. Perhaps that will help although I don't see anything relevant in the= changelog. Thanks, Allen Belletti AVP Ed.

Hi Rob, Did you try to upgrade the DB? Restoring it is only the beginning. Like I said before, under the engine, under packaging/dbscripts, run upgrade.sh .

[Users] Ovirt Engine Memory usage going crazy since 3.3 Upgrade
by squadra 12 Dec '13

12 Dec '13

Hi, i upgraded my Ovirt 3.2 a few days ago, with 3.2 memory usage was within a level i rated as normal (~3gb mem used, for controlling 6 nodes with about 30 vm on them). after 3.3.1 upgrade, the engine goes crazy and uses about 3x of memory after some hours. right after starting ovirt-engine, everything is fine, after about 20hrs the host starts swapping etc heres the process in "crazy state" ovirt 8749 107 59.2 10592340 4776040 ? Sl Dec10 2189:35 ovirt-engine -server -XX:+TieredCompilation -Xms1g -Xmx1g -XX:PermSize=256m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Dsun.rmi.dgc.client.gcInterva here right now after a restart ovirt 28350 43.7 8.7 3895304 705964 ? Sl 07:09 1:09 ovirt-engine -server -XX:+TieredCompilation -Xms1g -Xmx1g -XX:PermSize=256m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Dsun.rmi.dgc.client.gcInterval also, the webinterface is getting really laggy after a few hours of runtime (already before the host starts swapping). anyone got an idea what is causing this? which logs should i provide to dig further into this? thanks & cheers, Juergen -- Sent from the Delta quadrant using Borg technology!

Hi, When trying to add an NFS Export domain via oVirt-engine, it fails on "Problem while trying to mount target". when checking the vdsm.log, it seems that the problem is mount time-out. when I tried to manually run the mount command, in the exact same manner as vdsm, it indeed failed on Connection timed out after ~3 minutes or so: [root@localhost vdsm]# /usr/bin/mount -t nfs -o soft,nosharecache,timeo=600,retrans=6,nfsvers=3 1.2.3.4:/home/ecohen/public/export/engine/storage/195/iscsi-dc/export /rhev/data-center/mnt/11.2.3.4:_home_ecohen_public_export_engine_storage_195_iscsi-dc_export mount.nfs: Connection timed out but - when trying to run the mount command again, with the exact same mount source and mount target, but without any additional parameter, it succeeded (after ~10 seconds): [root@localhost vdsm]# /usr/bin/mount 10.18.57.137:/home/ecohen/public/export/engine/storage/195/iscsi-dc/export /rhev/data-center/mnt/10.18.57.137:_home_ecohen_public_export_engine_storage_195_iscsi-dc_export So I assume that I need to either configure my NFS Export folder differently, or create the storage domain with additional parameters (using the "Advanced Parameters" section in the GUI dialog or similar). any pointers on what exactly should be checked / done? many thanks in advance. ---- Regards, Einav

[Users] ovirt 3.3.1 all VMs boot on the same host?
by Gianluca Cecchi 11 Dec '13

Hello, I have a cluster of 2 hosts with f19 and 3.3.1 as delivered in ovirt stable repo. Running kernel is 3.11.8-200.fc19.x86_64 $ rpm -q ksm libvirt qemu-kvm vdsm package ksm is not installed libvirt-1.0.5.7-1.fc19.x86_64 qemu-kvm-1.4.2-13.fc19.x86_64 vdsm-4.13.0-11.fc19.x86_64 Engine is another server, always with f19 and ovirt stable 3.3.1. I have a GlusterFS DC with a cluster composed by these two hosts. They are HP blades BL685c G1 with 64Gb of ram each and 4xOpteron CPUs, seen by oVirt as "AMD Opteron G2" in datacenter. I have 3 VMs in this cluster: 2 x CentOS 6.4 and 1 x CentOS 5.10. After I put all in maintenance and then start up. I have both hosts up and running. I power on in sequence the 3 VMs and they start all on the same host (the one that is not the elected SPM). Should it be some sort of load balancing or is this situation correct/expected? I notice ksm is not installed: could it be this one the reason in any way? Or culd it be useful anyway to install it (I thought it was a dependency for oVirt...) $ rpm -qa|grep ksm [g.cecchi ]$ BTW: if I run a live migration of CentOS 5.10 VM to the other host it works ok without problem, so the host seems ok to me. All 3 VMs are configured as servers and as "run on any host in cluster" Thanks in advance, Gianluca
