[Users] CentOS 6 and multiple ISCSI interfaces/multipath
by Martin Goldstone 18 Jun '13

18 Jun '13

Hi all, I've recently started looking at oVirt to provide the next iteration of our virtualization infrastructure, as we have recently acquired some ISCSI storage. Up to now, we've been using KVM managed by libvirt/virt-manager locally on each of our hosts, using direct attached storage, which was obviously less than ideal. In setting it all up, I've hit a bit of a snag. We've got 4 GbE network interfaces on our pilot host (running vdsm on CentOS 6.4) which are connected to our storage arrays (equallogic). I've created 4 interfaces with iscsiadm for these and bound them, but when setting up the discs in oVirt, I've not seen a way of telling it which interfaces to use. The node makes the connection to the target successfully, but it seems its only connecting via the "default" iscsi interface, and not making a connection via each interface that I've defined. Obviously this means I can't use multipath, and being only GbE interfaces it means I'm not getting the performance I should. I've done some searching via Google, but I've not really found any thing that helps. Perhaps I've missed something, but can anyone give me any pointers for getting this to work across multiple interfaces? Thanks? Martin

HI All, I upgraded to 3.3 and tried to start a console. Whatever version of console I set, VNC or Spice, the browser downloads a console.vv file now. Am I doing something wrong or is this just the unreleased version ? Thanks for the help! Cheers, Matt

Hi guys, I've got some problems with my ovirt-engine. Currently I have one iscsi storage volume and I want add a second one. The second has the same configuration as the first. In my engine I can log into the iSCSI but I cannot see the LUN.

[Users] cpu stuck after joining fedora 18 node to ovirt
by Daniele Pavia 17 Jun '13

17 Jun '13

Dear all, we're facing this issue while trying to join a Fedora 18 server with the latest stable vdsm to an instance of ovirt-engine 3.2.2. Let's put things in context: we have this fujitsu rx200 server with a dual emulex fc nic connected with two fibres that go through two brocade switches, which in turn have four paths each to a vnx 5300 storage - that's a grand total of eight paths. Now. This server was previously employed as an ovirt node and was working correctly with the very same configuration, we simply reinstalled the server with the latest Fedora 18 stable release. The server boots fine and multipathd is already up and running. All the paths are valid and block devices are seen. Please note that those block devices contain our ovirt 's d.c. storage domains. We set up and enable ovirt's stable repo and proceed to install vdsmd, then we add the node from the webadmin interface. Bear in mind that we face the same issue by letting the engine install the vdsm daemon on its own. The node gets installed successfully and reboots. When the OS tries to initialize the storage we get this funny message about a random core getting stuck for xx seconds. Then it fails to mount /home and finally drops to the emergency shell. (see attachment) If we remove the host from the storage group and reboot it, it doesn't hang. A few things we tried to fix this up: * restored multipath.conf from a working node * put each mountpoint's uuid inside fstab * installed vdsm from fedora updates instead of the official ovirt stable * swapped two different fujitsu models (we had the same issue with another server: we swapped them and had the first one join a rhev infrastructure running on the same network without shedding a single tear) We consciously avoided installing ovirt node since we require more control out of our servers than such a minimal distribution will ever let us have, however we're willing to deploy it for troubleshooting purposes. Any feedback will be more than welcome. Cheers, Daniele Pavia

[Users] Starting VM gets paused
by Nicolas Ecarnot 16 Jun '13

16 Jun '13

Hi, After two months of stable usage of this 3.1 oVirt setup, here comes the first blocking issue for which I've no other mean to ask some hint. When I'm starting a VM, the start process is running fine. Being fast enough, we can ssh-connect to it, but 5 seconds later, the VM is paused. In the manager, I see that : 2013-03-22 09:42:57,435 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerObjectsBuilder] (QuartzScheduler_Worker-40) Error in parsing vm pause status.

I don't know if I have to conclude that this issue is specific to this VM, but I sounds like yes. Things to say about this VM : - it it a RH6 IIRC. It has already been successfully started, migrated, stopped and rebooted many times in the past. - it has 3 disks : one for the system and two for datas. - it has no snapshots - it has no different or complicated network setup My storage domain is a SAN, iSCSI linked, and doing good job since months. I must admit I'm a bit stuck. Last thing I haven't tried is to reboot the manager, though I'm not sure that would help. -- Nicolas Ecarnot
