why not?

that is :)
different name (in pvs) but same storage.
anyway, i will add a third machine and setup the storage over there, then i will setup 3 machines in cluster that see the same device name.

can that help?

yes but that could be a problem... cause i need to have (at least) a volume for each virtual machine.
or am i missing something like do a cluster filesystem and on top of that re-create the vg?

but anyway, i just need to see the filesystem as open...
do i need a clustered one to see the correct open attribute with lvs?
how does the open attribute is set?

thanks a lot!
