what do you mean by "gone"?
where exactly have "all files" been before?
where is the drbd mounted?
do you have heartbeat configured?
did your actions interfere with heartbeat actions?
please provide some log messages from that event.
you should have something like
kernel: drbd0: drbd0_receiver [###]: cstate WFConnection --> WFReportParams
kernel: drbd0: Handshake successful: DRBD Network Protocol version 74
kernel: drbd0: Connection established.
