Without any extra prodding, the primary (which is in recover mode)
began chatting madly to the secondary (which is in partner-down mode).
The lease file is growing rapidly.
The pause of several hours puzzles me. One little item: the hard disk
filled on the primary last night, and I cleared space and rebooted the
server. But the communication using the failover protocol was very
minimal for some hours after that. Then suddenly, it starts working again.
