Hello Pasi,

2. Do I need the Redhat-Cluster-framework for this to work? If I makechanges to the shared LVM VG (e.g. create a new LV for a new DomU), Ihave to execute vgscan on all Dom0s.This would not be necessary if I would use the cluster framework. But Idon't need GFS or such, so I don't want to add additional complexity.But perhaps I have overseen some metadata problems here? Anyone? :)
You need CLVM ("Cluster LVM") from Redhat-Cluster-framework. No need for
GFS.

Ok, what exactly is the clvm daemon for? Propagating changes to the VGsto all nodes accessing the VGs? Is it possible to do this manually withvgscan or such?


Regards,
Bjoern
