Hi, I've searched the docs (and slightly the sources) but I can't find a definitive answer about the following. Note that I'm using DRBD 8.0.12, not latest version. The man page for drbdsetup makes it sound like both ends of a drbd pair will ping the other in case of no activity. However, in practice on an unused device, only one of the two TCP connections that is used by the DRBD pair sees pings; the other one sees no traffic at all. (This would not usually be a problem, except that if one has iptables and conntrack enabled on the machine, and the device is not used for long enough time, the second TCP connection will be forgotten by the conntrack module) So, does anyone have more information about the ping rules? I.e. am I seeing this behaviour due to old version, or is this expected? thanks, iustin
