Sorry, the setting discovery.zen.minimum_master_nodes is 8

 Hi,
 We are using elasticsearch 0.90.1. We had some problems with the network, 
 when the network is down (the convergence time is around 40s). Recovering 
 the elastic after this event took a long time to be available. We have 16 
 data nodes and 16 shards with 2 replica and the settings:

 discovery.zen.minimum_master_nodes: 4
 gateway.recover_after_nodes: 4
 gateway.expected_nodes: 6

 Any idea about how to minimize the recovery time?
 Is it a good idea to update the version?
 What will happen if we increase discovery.zen.fd.ping_interval and 
 ping_timeout settings? Assuming the network is completely off, is there any 
 way to wait for at least those 40 seconds to start marking servers down? 
 Does the ping_timeout ignore the failure to connect to a node?


 Thanks.

Recovery is throttled since version 0.90.1

http://www.elasticsearch.org/guide/en/elasticsearch/reference/0.90/index-modules-store.html#store-throttling

Increase indices.store.throttle.max_bytes_per_sec to a level that is
suitable for your environment. Since IO should be the main bottleneck, the
setting could vary greatly depending on SSD, platter disk or shared storage.
