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. __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo! Messenger http://phonecard.yahoo.com/
