Nov 15 22:10:14 darwin kernel: Lustre: ddn_home-MDT0000-
mdc-00000100cff22800: Connection restored to service ddn_home-MDT0000
using nid 10.143.245.201 at tcp.

This message means that connection was restored to your MDS.
I cannot tell if it was indeed failover (sorry, I used wrong word),  
but I can tell this client disconnected from MDS previously and later  
reconnected to it by this message.
I assumed since you were speaking of failovers MDS might have been  
failed over as well (due to disconnection), but this is not necessary  
the case.
