Lars, you're right, I didn't understand the units when I posted. I tried two different settings. I tried "ping-timeout 100" which gave me really really bad results where i'd get the pingAck error very often. When I set ping-timeout 20 , the sync went for 1 hour and then pingAck error after that. While doing the drbd sync I was running a continous ping from the SyncSource node to the SyncTarget node and it was replying between 0.100 and 0.700 ms. > -- > : Lars Ellenberg http://www.linbit.com : > : DRBD/HA support and consulting sales at linbit.com : > : LINBIT Information Technologies GmbH Tel +43-1-8178292-0 : > : Vivenotgasse 48, A-1120 Vienna/Europe Fax +43-1-8178292-82 : > __ > please use the "List-Reply" function of your email client. > > _______________________________________________ > drbd-user mailing list > drbd-user at lists.linbit.com > http://lists.linbit.com/mailman/listinfo/drbd-user >
