We need to change this to 10 buckets not 6.

Buckets now limited to 10 by default. Limit is configurable using the max_bucket_count setting.

Added to RN and REST chapter:


 By default the maximum number of buckets recommended for a Couchbase Cluster is ten. This is a safety mechanism to ensure that a cluster does not have resource and CPU overuse due to too many buckets. This limit is configurable using the REST-API.
 The Couchbase REST-API has changed to enable you to change the default maximum number of buckets used in a Couchbase cluster. The maximum allowed buckets in this request is 128, however the suggested maximum number of buckets is ten per cluster. The following illustrates the endpoint and parameters used:

shell> curl -X -u admin:password -d maxBucketCount=6 http://ip_address:8091/internalSettings

 For this request you need to provide administrative credentials for the cluster. The following HTTP request will be sent:

About to connect() to 127.0.0.1 port 8091 (#0)
Trying 127.0.0.1...
connected
Connected to 127.0.0.1 (127.0.0.1) port 8091 (#0)
Server auth using Basic with user 'Administrator'
POST /internalSettings HTTP/1.1

 If Couchbase Server successfully changes the bucket limit for the cluster, you will get a HTTP 200 response:

HTTP/1.1 200 OK
Server: Couchbase Server 2.0.0r_501_gb614829
Pragma: no-cache
Date: Wed, 31 Oct 2012 21:21:48 GMT
Content-Type: application/json
Content-Length: 2
Cache-Control: no-cache

 If you provide an invalid number, such as 0, a negative number, or an amount over 128 buckets, you will get this error message:

 ["Unexpected server error, request logged."]
