Used (%): For Storage Nodes, the percentage of the total usable space for object data that has been used. This value does not include object metadata.

Select the ILM Usage tab to determine if the storage pool is currently being used in any ILM rules or Erasure Coding profiles.
In this example, the DC1 storage pool is used in three ILM rules: two rules that are in the active ILM policy and one rule that is not in the active policy.
You cannot remove a storage pool if it is used in an ILM rule. In this example, the All 3 Sites storage pool is used in an Erasure Coding profile. In turn, that Erasure Coding profile is used by one ILM rule in the active ILM policy.
You cannot remove a storage pool if it is used in an Erasure Coding profile. -
Optionally, go to the ILM Rules page to learn about and manage any rules that use the storage pool.
See the instructions for working with ILM rules.
