Hi Guys,<br><br>I am working on building a small cluster sharing the lustre file system. I will be using an infiniband interconnect for all the compute/head nodes. Can someone please assist me in figuring out which RPM's should I install on my MDS & OSS.:<br>
<br>kernel-ib-1.4.2-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>kernel-ib-1.4.2-2.6.18_128.7.1.el5.x86_64.rpm<br>kernel-lustre-2.6.18-128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>lustre-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>
lustre-client-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>lustre-client-modules-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>lustre-ldiskfs-3.0.9-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>lustre-modules-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm<br>
<br>Should I be installing the kernel-ib* rpm? I am planning on installing the drivers that the vendor provides for inifiniband. I am pretty new to this whole setup, so if any of this sounds too basic, my apologies in advance. <br>
<br>Also, what is the recommendation on using LVM for MDT's and OST's? Should it be avoided or there is not much of a performance hit if we use LVM.<br><br>And finally, is there any reasons why I should not use large size luns (approx. 2TB) for my OST's?<br>
<br>Thanks,<br>-J<br>
