Re: [Openstack] SAN and Fibrechannel with OpenStack
Thank you for your answer, I am not saying that I need a clustered filesystem, with clvm I just have all lvm-volumes available on all machines, but only one machine would attach to the filesystem of a specific LV at a time.

Re: [Openstack] SAN and Fibrechannel with OpenStack
Hi Diego, Thanks for your answer. I will definitely give openstack a try. Not only a try, I will try to make it work.

Re: [Openstack] SAN and Fibrechannel with OpenStack
I'm not sure that it would be particularly easy to make nova-volume support clustered filesystems; the current model only supports attaching a volume to a single instance at a time. Aside from that, it shouldn't be too hard to use fc as the data path instead of iscsi. We're looking at using iSER in a similar capacity. -nld On Wed, May 16, 2012 at 4:05 AM, Wolfgang Hennerbichler wolfgang.hennerbich...@risc-software.at wrote: dear openstack godfathers; I do plan to migrate from crappy vmware and some ibm based cloud stack to openstack and kvm. here's the thing: I am lucky enough to have decent hardware, all the compute nodes are interconnected via fibre channel. so I don't want and don't need iscsi. do you think I can make it with something like clvm?
