[Lustre-discuss] New to lustre - Help setting up Lustre

[Jagga Soorma]

Hi Guys,

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.:

kernel-ib-1.4.2-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm
kernel-ib-1.4.2-2.6.18_128.7.1.el5.x86_64.rpm
kernel-lustre-2.6.18-128.7.1.el5_lustre.1.8.1.1.x86_64.rpm
lustre-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm
lustre-client-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm
lustre-client-modules-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm
lustre-ldiskfs-3.0.9-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm
lustre-modules-1.8.1.1-2.6.18_128.7.1.el5_lustre.1.8.1.1.x86_64.rpm

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.

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.

And finally, is there any reasons why I should not use large size luns
(approx. 2TB) for my OST's?

Thanks,
-J
