How do I change the cluster memory limit?

In the web console click on buckets and then the little arrow next to the bucket name you want to increase. Clicking on this button should cause a drop down page of bucket information. In that drop down on the top right click the edit button. A screen should pop up that has the bucket quota. Simple increase the quota and click ok at the bottom of the screen.

But I want to change the cluster quota so I can increase the bucket. I originally setup the cluster quota to 512MB (2 x 256mb) and now I have two buckets each with 128MB so I’m using all the allocation. How can I change the cluster allocation?

/opt/couchbase/bin/couchbase-cli should let you do that.

Change the username, password, port and ram quota:
couchbase-cli cluster-init -c

So the command to change the cluster quota to 1024mb would be something like:

/opt/couchbase/bin/couchbase-cli cluster-init -c -u -p --cluster-init-ramsize=1024

Originally I had it setup to 256MB but that only let’s me have 2 buckets. How can I increase the cluster memory size?
