Lustre installation (flash demo)
A few days ago, I was putting together a demo of lustre for some teams in Sun interested in Lustre. Then yesterday I got another request for a demo, this time at a college in Tamil Nadu. This got me interested in producing a flash demo that can be reused.
So, with the help of vnc2swf and tightvnc, here is what I put together. On a virtual machine running CentOS 4.4 on my laptop, I show the setting up of an MDS, a OSS and a client on a single node. The filesystms are on top of loop devices.
Lustre Installation
Lustre Configuration
[Note: Right click and select 'Play' to play the demo.]
Here is what the demo does:
$ wget http://downloads.lustre.org/public/lustre/v1.6/latest/
$ wget http://downloads.lustre.org/public/lustre/v1.6/latest/
$ wget http://downloads.lustre.org/public/lustre/v1.6/latest/
$ wget http://downloads.lustre.org/public/lustre/v1.6/latest/
$ rpm -ivh kernel-lustre-smp-
$ rpm -ivh lustre-
$ rpm -ivh lustre-ldiskfs-
$ rpm -ivh lustre-modules-
$ reboot
[Select the newly added grub option to boot using the kernel with lustre patches.]
$ mkfs.lustre --reformat --device-size=300000 --fsname lustre --mdt --mgs /tmp/lustre-mdt
$ mount -t lustre -o loop /tmp/lustre-mdt /mnt/mds
$ mkfs.lustre --reformat --device-size=1000000 --fsname lustre --ost --mgsnode=${MDS}@tcp0 /tmp/lustre-ost1
$ mount -t lustre -o loop /tmp/lustre-ost1 /mnt/ost1
$ mount -t lustre ${MDS}@tcp0:/lustre /mnt/lustre
As you can see, it is quite simple - a big change from the lustre 1.4.x days! 
Download lustre packages from here
Good demo for people who has to learn & startup lustre.
