Hello all, With Ubuntu 14.04 (drbd 8.4.4), I cannot get more than 40MBps out of the initial DRBD initialization sync no matter what settings (sync-rate, c-max-rate, c-min-rate, etc). I've been playing with this for tens of hours now. I've tried drbd 8.4.5 and above to no avail.
With Ubuntu 12.04 (drbd 8.4.3) I can max out a 10GbE NIC without issue on the same hardware. Unfortunately, Ubuntu 12.04 does not play nice with MegaRAID. So, either I need to fix drbd on 14.04 or fix MegaRAID on 12.04 (which does not appear to be an option). Regards, Darren
