I am getting following error when started the FDB on 1st node (planning to use 3 node cluster). Any idea to fix this. I am ok to start from over as this is test deployment only.

```auto
fdb> status

Using cluster file `/etc/foundationdb/fdb.cluster'.

Could not communicate with a quorum of coordination servers:
  127.0.0.1:4500 (unreachable)

I have following configuration file setup 
foundationdb.conf
##

I don’t see a `[fdbserver.4500]` section in the conf file. Is it missing? If so, then it might just be that no process is started on the port where the cluster file says you have a coordinator.

yep this problem is fixed. I was not clear initially that I can start storage process on the same port 4500 . I was under impression coordinator is running on 4500 so i should run storage on 4501/4502 as i was using 2 processes and thought having 3 process on 3 ports will use 3 cpu out of 4 on the EC2 .

Little confusing when you read FDB document first time … new to FDB and learning …thanks for the reply.
