Hi, I have a DRBD setup with primary and secondary. DRBD0 is a RAID6 array, and DRBD1 is a RAID1 array. A couple of time a day, DRBD1 forces a re-sync due to PingAck not arriving in time, yet DRBD0 never has that issue. Both sync over the same dedicated GigE link. DRBD0 is in use, while DRBD1 isn't yet. Running stock Ubuntu 12.10
Is there anything I can do about this?
