We have a little SAN storage and using LVM2 to manage the storage. It is possible to create one volume group with logical volumes for both hosts. So I could create one volume group and use the logical volumes for XEN DomUs on both hosts. The only thing I have to do is activate the logical volumes either all volumes of the VG or each logical volumes separately.
But is this a good idea? Is this how it should work or is this a misuage and LVM2 is not capable of preventing such a configuration?
