Compression reduces the amount of data stored or transmitted to improve performance. Data in transit is always compressed to reduce network traffic, and data at rest is compressed by default but can be disabled.

Create a uncompressed volume

All volumes are compressed by default. To create an uncompressed volume, set the storageos.feature.nocompression label:

storageos volume create --namespace default --label storageos.feature.nocompression=true volume-name

or the Docker CLI:

$ docker volume create --driver storageos --opt size=15 --opt storageos.feature.nocompression=true volume-name
