Upgraded infernalis->jewel (git, Gentoo). Upgrade passed over global
stop/restart everything oneshot.
Infernalis: e5165: 1/1/1 up {0=c=up:active}, 1 up:standby-replay, 1 up:standby
Now after upgrade start and next mon restart, active monitor falls with
"assert(info.state == MDSMap::STATE_STANDBY)" (even without running mds) . Fixed:

Now: e5442: 1/1/1 up {0=a=up:active}, 1 up:standby
- but really there are 3 mds (active, replay, standby).

How to fix this 3-mds behaviour?
