Hi,<br>
<br>
to enable NFS state transfer between hosts in a failover SAN, it is
necessary to have the NFS state data on the exact same blocks on
both storage nodes:<br>

<br>
Simply linking /usr/lib/nfs to the glusterfs volume doesn't work.<br>
<br>
My questions:<br>
Can I somehow enable block-for-block replication with GlusterFS?<br>
What is this:
