We saw this the other day. The default bucket in this case was not full, and it wouldn't let us increase the bucket size, when the server(s) seemed to have plenty of available memory for it.

Once this happened, no servers could come in or out of the cluster (showed pending the whole time).

Restarting the service and the server didn't help.

We just use the default bucket, and re-installing was a quick as anything.

How have others resolved/worked around this?

Thanks!

Hi There,

So you may have hit the memory quota for the node when trying to increase bucket size. On a default install Membase will recommend 90% of ram as the default memory quota and the default bucket size is spec'ed to the default memory quota. If you've gone with the defaults - you cannot increase the bucket size until you increase the nodes memory quota.

Here are some links for how to do so:
