Actually as I understand it there is a difference between raw "character" devices and block disk devices -- apparently there is a difference.

This is an interesting thread that touches on the subject... http://forums.oracle.com/forums/thread.jspa?threadID=498215&tstart=-1

An excerpt:
I experimented with all ASM variants on Unbreakable Linux 4.4:

• on raw-bound character devices (/dev/raw/raw*)
• on block devices (/dev/hd**) with ASMLib installed
• on block devices (/dev/hd**) without ASMLib installed

and all variants worked fine. I couldn't find out which variant had the best performance testing it on single-user uniprocessor system. Received on Mon Apr 30 2007 - 18:01:29 CDT
