Hi I was just wondering how multipath iscsi is handled in 3.5. In 3.4 there is a button on the web interface under the data center tab that could be used to configure multipathing for storage domains but not direct luns. This seems to be missing in 3.5 Beta from what i can tell. We are particularly interested if multipathing will work with direct lun, as we have to keep bodging custom changes into the vdsm python with each new version. (We currently use EqualLogic).

The oVirt team is pleased to announce that the 3.5.0 Beta is now available for testing.

Feel free to join us testing it!

You'll find all needed info for installing it on the release notes page, already available on the wiki [1].

A new oVirt Live iso is already available for testing[2] including all available updates from CentOS. An oVirt Guest Tools iso is now available too[3].

A new oVirt Node build will be available soon as well.

Please note that mirrors will 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.

Known Issues * if you're using f19 host, you'll need libvirt >= 1.0.1 to use cluster level 3.5 (pkg will be provided from ovirt repo, but if it not there, you can update from f20 repo: : yum update --releasever=20 libvirt\* ) * You can't refresh iso file list after adding a host, see https://bugzilla.redhat.com/show_bug.cgi?id=1114499 for a workarond.

If this is not available in 3.4, it will also not be in 3.5 - nobody wo= rked on such feature in 3.5.

We are particularly interested if multipathing will work with direct l= un, as we have to keep bodging custom changes into the vdsm python with each = new version. (We currently use EqualLogic).

The best way to avoid customizing vdsm is to get your patches merged up= stream.

Do you want to describe what are you trying to do, and how do you modif= y vdsm?

I've had similar issues with Equallogic, as Gary has described earlier=20 here:=20 https://sites.google.com/a/keele.ac.uk/partlycloudy/ovirt/gettingovirttow= orkwithdellequallogic. I've used his patch as a baseline (thanks for the original effort,=20 Gary!) with some minor fixes/additions and the code can be found here:=20 https://github.com/futurice/vdsm/tree/equallogic-multiple-iscsi-ifaces The main issue seems to be that VDSM didn't work properly when multiple=20 network interfaces are used to connect to the iSCSI storage, as is the=20 situation with our Equallogic installation. The patch is currently=20 against vdsm version 4.13.2 and we've been using it as well with=20 version 4.13.3. Nir, feel free to comment. I am not sure if this patch is ready for=20 upstream yet, but hopefully it illustrates some issues that may need=20 solving.
