For that purpose I created a copy of the node's filesystem in a /tftpboot directory. That is, I have a full filesytem for each single node : /tftpboot/192.168.1.1, /tftpboot/192.168.1.2, /tftpboot/192.168.1.3, etc. </div> <div><br></div> <div>I know that there are several different options to make several clients mounting their filesystems, and that this one might not be the most efficient one, but I choosed that one just because I knew already how to do it. Now everything works fine, except that I would like to spare some diskspace on the master partition. Since each filesystem is around 500 Mb, I quickly reach more than 10Gb just for the /tftpboot directory. </div> <div><br></div> <div>A quick solution I founded is to mount the largests directory (which are the same for each node) of the / (namely /lib and /var) from a separate common directory. Could this cause some problem in the way the node's are working? Is there any other easy/fast way to reduce the amount of data contained in the /tftpboot/192.168.1.* directories?</div> <div><br></div> <div>I also heard about ClusterNFS which would do exactly what I need, but then I would have to start everything from the beggining and I want everything to work as soon as possible. </div> <div><br></div> <div>Thanks a lot for answers/advices,</div><br> <div><span style="WORD-SPACING: 0px; FONT: 12px Georgia; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate; border-spacing: 0px 0px"> <div style="WORD-WRAP: break-word"> <div>------------------</div> <div>Maxime Kinet</div> <div>Université Libre de Bruxelles</div> <div>Physique Statistique et Plasmas, CP 231</div> <div>Campus Plaine - Boulevard du Triomphe,</div> <div>1050 Bruxelles.</div> <div><br></div> <div><br></div></div><br></span></div><br></div><br>_______________________________________________<br>Beowulf mailing list, <a href="mailto:Beowulf@beowulf.org">Beowulf@beowulf.org</a><br>To change your subscription (digest mode or unsubscribe) visit <a href="http://www.beowulf.org/mailman/listinfo/beowulf" target="_blank">http://www.beowulf.org/mailman/listinfo/beowulf</a><br> <br></blockquote></div><br></blockquote></div><br></body></html>
