ROCKS Clustering - A Review

Wednesday, July 19th, 2006

This is “NOT” a HowTo for setting up a ROCKS Cluster, but I tried to show ya off some of my try outs and some aftermath.

If ya are new to ROCKS; Please refer the well equipped ROCKS User’s Guide or ya might be lost.

I used VERSION:-4.1 [Rocks v4.2 Beta is released for i386 and x86_64 CPU architectures are avail now]
and my cluster details are registered here

Frontend a.k.a Head Node installation is just a breeze, only if ya refer the manual.

To saY a word about frontend installation, what is your requirement so what rolls ya need to select.

BASE DISK
0.Area51 Roll :- For added security features like Tripwire and chkrootkit. Opt-out, if you really not othered about high-funda security.
1.Viz Roll :- Visualization, you don’t required unless you have a big and tiled monitor.
2.hpc :- Yes, I am into HPC lane
3.Ganglia :- To show off my cluster set-up and obviously for cluster’s health monitoring.
4.Web-server :- Yes.
5.Kernel Roll :- Yes.

OS DISK

Disk-1 and Disk-2 is sufficient, disks-3 and 4 are optinal

..and next, I did bind to our local ntp server.

DISK PARTITIONING -> Disk-druid for my 147 GB SCSI

/boot : 128 MB
/ : 15 GB
/usr/local : 20 GB ( For mannual installation og Globus and Torque scheduler)
/var : 25 GB (I expect a little more log)
swap : 2 GB
/myspace : 10 GB (For the non-cluster/local users home directory)
/export : Fill Available space

Now the installation has got over; system booted-up and no color (GUI) :-)

# system-config-display

To say, I had an issue and I dont want to see the smoke behind my flat BenQ. What I did was just copied
the /etc/Xll/xorg.conf file from another system with “same” hardware loadead with RedHat-AS-4.
I repeat… Linux, its a large file ! ;-)

Oh..yeah monitor, it’s single BenQ flat, shared over the systems with ATEN KVM switch.

#startx
…hoo·ray ! I got the color ( when ya logged in, the only difference I felt, there wasn’t any red HAT logo but centOS and the grub was different…. so Luke… its our shadow-man ! )
…then I stopped smartd service.

Compue Node Installation

Sigh !
