[Xen-API] One resource pool and local lvm SR mirrored using DRBD

[Jakob Praher <jakob@xxxxxxxxxxx>]

Dear List,

I have a question regarding a fault-tolerant setup of XCP.
We have two hosts that are in one resource pool.
Furthermore we are trying to make two SRs (storage repos) as local lvm
volume groups where one volume group is active (owned) by one server,
and the other volume group is active on the other server.

In case of failure because of the common resource pool all the meta
information concerning VMs are still available. After degrading the
system to one host the SR is still owned by the failed server. Is there
an easy way to migrate the SR? Is anybody using a similar solution or
what are your best practices?

I think CrossPool-Migration is not an option for us since we want to
keep only one resource pool for both servers.

Another question: I am currently using 1.1 of XCP - what is the best way
to compile system (like DRBD) RPMs for this version. Since the DDK is
not available I also have troubles getting the XCP distribition
installed into a guest VM so that I can add development packages to it
and compile the package there. Is there a base image that I can use so
that I have the right devel rpms? From yum repos.d I see that it is a
CentOS 5.

Any help is appreaciated.

Cheers,
Jakob
