Hi, While upgrading my system, i have encountered a situation where both peers are alive and well, but drbd can still not establish a connection without removing and reinserting the drbd modules first. This happend after i rebooted the second system with an older kernel which prompted the first system to terminate it's drbd receiver threads. The log from the first peer: Jul 22 12:31:03 sdev01 kernel: drbd0: expected HandShake packet, received ReportParams... Jul 22 12:31:03 sdev01 kernel: drbd0: peer probaly runs some incompatible 0.7 -preX version Jul 22 12:31:03 sdev01 kernel: drbd0: Discarding network configuration. Jul 22 12:31:04 sdev01 kernel: drbd1: expected HandShake packet, received ReportParams... Jul 22 12:31:04 sdev01 kernel: drbd1: peer probaly runs some incompatible 0.7 -preX version Jul 22 12:31:04 sdev01 kernel: drbd1: Discarding network configuration. Jul 22 12:31:04 sdev01 kernel: drbd1: worker terminated Jul 22 12:31:04 sdev01 kernel: drbd1: Connection lost. Jul 22 12:31:04 sdev01 kernel: drbd1: receiver terminated Jul 22 12:31:04 sdev01 kernel: drbd2: expected HandShake packet, received ReportParams... Jul 22 12:31:04 sdev01 kernel: drbd2: peer probaly runs some incompatible 0.7 -preX version Jul 22 12:31:04 sdev01 kernel: drbd2: Discarding network configuration. Jul 22 12:31:04 sdev01 kernel: drbd2: worker terminated Jul 22 12:31:04 sdev01 kernel: drbd2: Connection lost. Jul 22 12:31:04 sdev01 kernel: drbd2: receiver terminated Jul 22 12:31:04 sdev01 kernel: drbd0: worker terminated Jul 22 12:31:04 sdev01 kernel: drbd0: Connection lost. Jul 22 12:31:04 sdev01 kernel: drbd0: receiver terminated ... here all receivers are gone and drbd needs to reloaded to start working again. I have to admit that this is a situation that should not happen in production, but i would also argue that _nothing_ should leave a drbd peer in a state from which it can not recover automaticly.
