Hi
I was just wondering how multipath iscsi is handled in 3.5. In 3.4 the= re is a button on the web interface under the data center tab that could be us= ed to configure multipathing for storage domains but not direct luns. This seems to be missing in 3.5 Beta from what i can tell.
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.
