ROCKS Clustering - A Review
Wednesday, July 19th, 2006This 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.
