Hi, As specified here: http://www.drbd.org/users-guide-8.3/s-latency-tuning.html I'd like to tune some params. But, in: echo deadline > /sys/block/device/queue/scheduler what is 'device'? I have an LV on RAID as a DRBD back-end. Which of these devices do I change the scheduler of: /dev/sda and /dev/sdb /dev/md1 /dev/dm-3 (being a link to the LV in question. And, do they interfere when one is CFQ and another deadline? Another point is, are those /dev/dm-x devices consistent on reboots? Thanks, Wiebe
