Subject Re: Shared Storage for VMs
Date Sat, 13 Dec 2014 01:45:56 GMT
I have this requirement for some of the applications deployed in CS too

Workaround solution (of sorts) was to create a Shared Network attached to a
Physical VLAN & then hook up a Physical NAS to the same VLAN.
The shared network is bound to a particular account / project so that it
can't be used by everyone

For me part of the attraction of using CS over OpenStack was that you could
craft the network in this way so that you an support applications /
deployments which have physical device requirements or haven't been
developed to be 100% cloudy.

I notice that OpenStack is looking into a shared volume system, & I'd also
like the option of doing it 100% inside of CS if it was capable of doing so.

I do recall though that in XenServer (& ESX 4 I think) it wasn't possible
to attach a single volume to multiple machines without significant hacking
of the underlying Python - after which building things like an Oracle RAC /
GRID system or OCFS2 was possible but this is probably out of reach for
most users.

Perhaps something like a Virtual NAS VM like the Virtual Routers etc. would
be sufficient - think OpenFiler but inside of CS?
