Hi,


How do i set the nr_request value for LV's as it's not writable like other
drives on a linux system.

LV's are set as dm-0 and dm-1 on my system.

 #cat /sys/block/dm-0/queue/nr_requests
128
# echo 256 > /sys/block/dm-0/queue/nr_requests
-bash: echo: write error: Invalid argument
#

Thanks,

Pankaj
