I have set up a Linux-HA configuration on two systems. DRBD is working, but
the speed is very low. It never exceeds 500 Kb. Although I've set rate in
drbd.conf to 700000. Could someone help me with this problem or give me some
direction, at the moment I don't know if the source of the problem lays in
DRBD or maybe in the filesystem.
