How to expand "Usable Free Space" from disk?


#1

Hello everybody!

We have a cluster running with Couchbase 4.0 CE that required expanding the disk size (LVM over XFS). That went all right and the cluster overview have noticed the change as well increasing the free space available but not the “Usable Free Space” marked with a ‘red line’ that’s visible in the following image.

What I can do in order to increase that Usable Free Space and move the red line to the right? :slight_smile:
Do I have to force a rebalance?

Thanks in advance!

You just need to increase the available space in the filesystem you have selected as the data directory for each node in the cluster (default /opt/couchbase/var/lib/couchbase/ on Linux).

No rebalance is required.
