Hi, We have encountered the following problem with drbd in all versions from about 5.x to 7.4, and any help would be much appreciated. We have a master and a slave machine, running on the same subnet. Occasionally when we stop drbd on the secondary and then start it, drbd will fail to see the master. Instead the secondary will report that it is: Secondary/Unknown and the master will be Primary/Unknown. Of course the network is fine and it is possible to ping, ssh, etc the master from the secondary. It is only drbd which cannot detect each other. It is sometimes possible to force the machines to 'see' each other by running drbdadm connect all, but this may need to be done several times until it has an effect. Has anybody else had similar problems, and how did they resolve them? Also, we are connecting our machines via a Gigabit ethernet connection on a private switched network. Can anybody give me an idea of how to tweak the drbd.conf file in order to maximise the bandwith available? many thanks Gareth Ansell
