I have a 3 servers cluster (it's a test but the hardware is what i'll put
in production)

In these 3 servers i'm running master and chunkservers, thus, i have 3
chunkservers

I've not checked for any disconnected chunkserver but it should block after
2 disconnected chunkservers, right?
In a 3 nodes cluster, quorum is met at 2, so it should survive at 1
chunkserver failure and i'm pretty sure that i don't have 2 chunkservers
down during the master switch

Anyway, is an odd number of metadata servers/chunkservers suggested?
Because on an even number, splitbrain could arise and quorum can't always
be met. (4 nodes, 2 down. Splitbrain and no quorum)
