<p class="MsoNormal">I am interested in the crypt translator of glusterfs. Kaushal M told me that there is no maintainer at the moment. Does anybody of you know some technical details about that translator?<o:p></o:p></p>

<p class="MsoNormal">Today there is still no support for NFS Mounts. Is there a way to enable crypt translator for nfs mounts?<o:p></o:p></p>
