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,

Ok. As a note, I plan to use DRBD in active/active setup as a storage
backend.
Thank you Steven.
