Subject Re: two XenServer Pools on the same primary Storage?
Date Mon, 12 Sep 2016 08:24:54 GMT
Hi Stephan,

Zone-wide (i.e. multi-cluster) primary storage is only supported on KVM and VMware, not XenServer.

Just so we are on the same page though – this applies at a LUN level – in other words
two XenServer pools can never share a LUN, but they can both use different LUNs from the same
storage backend.

And yes – to answer your question – using the same LUN on multiple clusters is pretty
much guaranteed to cause you problems – most likely data corruption and complete loss of

    I've recently expanded our XenServer Pool and had to notice that E5-

    Anyway. I'ld start introducing a new XenServer Pool (ACS Cluster) with
    that newer CPU Generation.
    My Question is: Is it possible to use the same (FC/presetup) Primary
    Storages for both Clusters?
    I've seen (which defaults to false)
    but currently don't know if this would need to be set to true on the
    second cluster.
    Would you expect any problems running two XenServer Pools (say: two ACS
    Clusters) with the same Primary Storages?
    Thanks for any advice!
