<<Expanding a Volume | Table of Contents | Migrating a Volume>>

You can shrink a volume, as required, by removing server partitions from an existing volume.

Note: You need to remove at least one server partition from a distributed volume, two (or multiples of two) server partitions from mirrored distributed volumes, and four (or multiples of four) server partitions from striped distributed volumes when shrinking the storage space.

    Note: Shrinking a volume can result in the loss of data from the removed server partitions.

  6. Click Save.
