Thanks everyone for replying. Special thanks to Bill Ryan, Jim Turner, Abramson
and Stuart. The verdict is as follows:
Multiple of 8K are fine.
Quote from Jim Turner:
Usually, you want your LVM stripe size to be equal to or a multiple of the produ
ct of Oracle block size * Oracle multiblock read count.
For example:
Oracle block size = 8k
Oracle multiblock read count = 16
8k * 16 = 128k
Recommended LVM stripe size = 128k or 256k
LVM allows you to create stripes in any power of 2 from 4k up to 1M.
In case you have not set the multiblock thread in the init.ora file then, the re
ad is based on the oracle block size(that is a guess).
I have some notes on disk partitioning sent in by Stuart. In case any one wants
them then do let me know. I would be happy to email it to you.
Thanks again Gurus !
Regards
Neeraj
