(the latter is not exactly trivial, either...) We have one cluster using drbds as physical volumes and I would just like to know what you mean with "not exactly trivial" as for now it works like a charm but I dont want to bump into some things I didnt think of in advcane later. Are there any special considerations to take except that one has to prevent LVM from detecting the underlying partitions as physical volumes? Thanks for any hints, Christof
