Re: [Xen-users] xen cloud - shared storage question



If you know DRBD, why not to use it on Dom0 ? Xen can directly use "drbd" devices.

hehe it's not that i don't like it, the hole setup makes sense but i'm just thinking about how to implement this in my situation :-), so basicly let's say i have 4 servers (physicial) i could take 2 for running the vm's, and 2 for actualy holding the vm's and replicate those last 2 servers with drbd or something like that..

    Yes the VMs will be stored on the NFS sr, and yes that's a SPOF.
    if you don't like that, replicate the storage box

        Ok that makes sense, so i would have to have an extra server
        configured with NFS that he uses to migrate, or are the actual
        VM's have to be stored on that NFS sr? Because doesn't that
        mean that you will have a single point of failure, the NFS
server?

            The standard setups needs a third shared storage box

                I'm pretty succesfull in deploying the xen cloud, but
                i only got 1 big issue at this moment, when i
                installed the host software, i just installed all the
                basic stuff, and now i would like to share the storage
                of node 1 with node 2, and vica versa so i can migrate
                (live?) vm's from 1 to 2 and back, i created a
                storrage pool and this seemed to work.. but while
                trying to migrate i got an error that there was no
                shared sr..

                is there a way to share the default hd's of the 2 hosts?

                Thanks,
                Peter
