There is no siginificant overhead when reading the same file on multiple nodes. The overhead mostly applies when writes are involved in some form, whether mixed with other writes or reads. GFS2 does ensure cache coherency, but in order to do that it requires certain properties from the storage, and hence the requirement for a symmetric view of the storage, Steve.
Ok. As a note, I plan to use DRBD in active/active setup as a storage backend.
