<title>RE: [Gluster-users] Cluster with NFS</title>
</head>
<body>
<p>Thanks Marcus.</p><p>I understand ... The Native Gluster client have very poor performance ...</p><p>If i use NFS i could mount on an IPFailover. If one of the fileserver is down, the IPfailover switch one the second Fileserver (not managed by Gluster Client but the only the network).</p><p>Next test, i will install debian-zfs package and try to use this filesystem with GlusterFS.</p><p><br></p><blockquote style="border-left: 2px solid #325FBA; padding-left: 5px; margin-left: 5px; margin-right: 0px;">-----Message initial-----<br><strong>De:</strong> Marcus Bointon <marcus@synchromedia.co.uk><br><strong>Envoyé:</strong> vendredi 27 septembre 2013 16:06<br><strong>À:</strong> Gluster-users@gluster.org List <gluster-users@gluster.org><br><strong>Sujet:</strong> Re: [Gluster-users] Cluster with NFS<br><br><base target="_blank">
