<p class="MsoNormal">For technical reasons, this test node will not be added to production. A previous thread <a href="http://www.spectrumscale.org/pipermail/gpfsug-discuss/2016-April/001529.html">http://www.spectrumscale.org/pipermail/gpfsug-discuss/2016-April/001529.html</a>
indicated that this will be OK. However, it is better to get a clear conclusion before we update other client nodes. Shall we recompile the kernel? Thanks all.
