Well, that's not patching the kernel. It's making the initrd and and
updating the boot stuff so your system will boot that kernel.
But, yes, that should be what you need to do.

When you say install the associated kernel do you mean patching the
kernel like below
sudo /sbin/new-kernel-pkg --package kernel --mkinitrd --dracut
--depmod --install 2.6.32-573.12.1.el6_lustre.x86_64
I have already done rpm -ivh kernel-2.6.32-573.12.1.el6_lustre.x86_64.rpm

The kernel version is found with uname -r or cat /proc/version.
That needs to match the kernel version in the Lustre RPMs. (The
version string is the 2.6.32-573.12.1.el6_lustre) part.
In fact, it looks like you've got Lustre server RPMs, given the
_lustre in the name of the kernel. That means you need to install
the associated kernel.

Patrick,
The CentOS version on the machines is 6.8
[lustre@hulk2 ~]$ cat /etc/redhat-release
CentOS release 6.8 (Final)
The kernel version that I have installed is what I found along with
the lustre RPMs
[lustre@amaranth3 ~]$ uname -r
2.6.32-573.12.1.el6_lustre.x86_64
And I am trying to install lustre 2.8.
Should the CentOS release version be 2.7??

Well, it says to check dmesg... Though that will just list the
symbols. In general, this usually means you've got a mismatch
between the version of the kernel (or OFED) Lustre is built against
and your version of either the kernel or OFED. Given the number
and locations of the mismatches, I'm guessing it's the kernel.
So, compare your kernel version and your Lustre RPMs.

Hi,
Below are the steps I executed in configuring MDS.
1. mkfs.lustre --fsname lustre --mdt --mgs /dev/vg00/mdt
2. mkdir /mdt
3. mount -t lustre /dev/vg00/mdt /mdt
I see the below error after step 3:
mount.lustre: mount /dev/mapper/vg00-mdt1 at /mdt failed: No such
device
Are the lustre modules loaded?
Check /etc/modprobe.conf and /proc/filesystems
[root@amaranth3 lustre]#
I tried modprobe lustre and retried mounting but it resulted in
the same error. Any help will be appreciated.
For your info, the lustre modules that I have installed are:
