Subject: bdev manipulation at block layer level
Date: Wed, 25 Jul 2001 02:17:16 -0700 (PDT)	[thread overview]
Message-ID: <20010725091716.71588.qmail@web11502.mail.yahoo.com> (raw)

Hi,

I have a host PC connected to a disk array with
alternate paths to an end scsi disk. 
I attempted load balancing across paths by changing
the b_dev & b_rdev ib the bufer_head list in
ll_rw_block function of ll_rw_blk.c (block layer), and
was successful in load balancing with data integrity,
on linux 2.2.16.
However, when I try the same stunt with a linux 2.4 (
&2.4.2) kernel, I am seeing corruption occasionally.
Can anyone let me know if I am missing anything ?

Thanks !

regards,
Satish.
