[libvirt-users] Multipath pools - practical for use?

Hi all, Writing up some Fedora documentation, and looking to figure out the best way of mapping multipath network(!) LUNs to pools in libvirt. ie Infiniband SRP LUNs, but would probably apply to Fibre Channel equally as well. There are two approaches I can think of easily: a) Large LUNs (ie TB+) that are mapped to a host server as disk, with each LUN being configured as an LVM pool. This lets the host slice the pool up into volumes with the libvirt volume creation commands. b) Pre-purposed LUNs mapped to a host server as disk, but passed through directly to their respective guests. ie Something like Oracle, with 3 SAN LUNs mapped to guest FOO for its database data In a non-libvirt world I'd look at configuring the LUNs on the host with persistent name using multipath, then present them appropriately to whatever needs them from there. However, libvirt has a pool type called "multipath". Looking at the docs online, it doesn't appear to be all that fully featured at this point. Seems more of a brief mention and footnote, so I'm wondering whether to use it or skip it for now in the Fedora docs. Anyone have thoughts/suggestions/etc? :) Regards and best wishes, Justin Clift -- Salasaga - Open Source eLearning IDE http://www.salasaga.org
