Deployment Must Have Sufficient Storage
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The decommissioning process migrates objects from the target pool to other
pools in the deployment. The total available storage on the deployment
*must* exceed the total storage of the decommissioned pool.

For example, consider a deployment with the following distribution of

Use the `Erasure Code Calculator <https://min.io/product/erasure-code-calculator>`__ to determine the usable storage capacity.
Then reduce that by the size of the objects already on the deployment.

Decommissioning Pool 1 requires distributing the 100TB of used storage

storage space and can safely absorb the data stored on Pool 1.

However, if Pool 1 were full (e.g. 200TB of used space), decommissioning would
completely fill the remaining pools and potentially prevent any further write
