Hi,

Looks like you are doing something that is not part of the design.

This is what I understood from your mail :

glusterv01 and glusterv02 are the nodes that constitute your glusterfs volume.
opennebula01 is where you have "mounted" this gluster volume. You can write/create
files only from this mount such that the files get replicate to both
glusterv01 and glusterv02 nodes. If you directly write into these nodes,
the files won't get replicated.

Does this answer your question? Let me know if it does not.
