[Gluster-users] Access to Servers hangs after stop one server...

[Diego Remolina]

Glusterfs needs quorum, so if you have two servers and one goes down, there
is no quorum, so all writes stop until the server comes back up. You can
add a third server as an arbiter which does not store data in the bricks,
but still uses some minimal space (to keep metadata for the files).

HTH,
