Creation of LVM in 32 bit
 

Hi I am using laptop of 32 bit. Since i have only 7GB free on my hard disk, so I want to create LVM with another 8GB USB pen drive. Then the space will be 15GB. Before doing this stuff, I want to know whether LVM can be created in 32-bit since my laptop is 32-bit????

Yes you can...

Pen drives aren't made for the speed and duty-cycles needed to use them as hard disk replacements. So while you CAN do what you are asking, you won't be happy with the resulting speed, or the length of time your pen drive lasts before it dies from overuse.
