I had a 3 member replica set running on my laptop. Small database, only used for training class.

Had to reboot the laptop.

After rebooting, restarted the replica set members. What had been the primary recovered, became a secondary, and waited for the other members, according to rs.status().

What had been secondaries went into some kind of recovery spin, creating many 2G local.N files, until I finally killed them.

Logs for the three servers from the point of restart are attached.
