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:
[root@amaranth3 lustre]# rpm -qa |grep lustre
