Hi,
Howto use Heartbeat and EVMS (in dom0) to create cluster aware logical
volumes for hosting Xen domUs...
Heartbeat 2.0.4 or later
EVMS 2.5.5 or later
hb2-1.0.0.so is the EVMS plugin for Heartbeat2
Add these lines to your /etc/ha.d/ha.cf
respawn root /sbin/evmsd
apiauth evms uid=hacluster,root
Start Heartbeat2 and it'll start the EVMS daemon on each node.
You can verify the cluster aware behavior of EVMS using e.g.
evmsgui->Settings->Node Administered...
If you see all of your cluster nodes listed, then EVMS and Heartbeat
and interacting properly.
You can use EVMS to create a logical volume per each Xen domU OS image
etc. E.g. perhaps you want to create an 10G image of hda corresponding
to a Xen guest, you might create /dev/evms/MyVirtualMachineHda, and copy
the guest OS image into that logical volume. The logical volume will
have the same (persistent) device name across all cluster nodes, which
means the corresponding Xen control file will be location transparent
too - i.e. it can reference /dev/evms/MyVirtualMachineHda as the path
for domU's hda, on all nodes.
Robert:
Why don't you put this up on the web site?
We can even add a Xen link to the quick links on the right.
