shell script to create multiple LVM's or raw devices for syabse

ganaiwali — Tue, 22 Mar 2011 11:17:13 GMT

I have Disk /dev/cciss/c0d1: 599.9 GB, unallocated on CentOS release 5.4 .

I need to create about 30-40 LVM's worth 500GB as raw devices for sybase . is there a way to script it or anyone already has it ?

the problem is that each time we need to do fdisk /dev/cciss/c0d1 and enter the partition no to create a new one .. how to overcome that problem and automate it in a script ?

thx,
tariq

I've read that there exists a program called "cfdisk" which takes partition numbers, etc. from the command line.

I see it here:

http://www.gnu.org/software/fdisk/

Introduction

GNU fdisk provides alternatives to the following programs:

* util-linux fdisk (compatible clone lfdisk, extended clone gfdisk)
* util-linux cfdisk

Some time ago I wrote a little Python script to create lvms from saved layouts. You may also alter that layout and mass create your volumes with it.
