Set the snapshot reserve

You can specify a minimum percentage of cluster-storage capacity that you want to reserve for snapshots.

About this task

The snapshot reserve does not limit the amount of space that snapshots are allowed to consume on the cluster. Snapshots can consume more than the percentage of capacity specified by the snapshot reserve. It is recommended that you do not specify a snapshot reserve.

This procedure is available only through the command-line interface (CLI).

Procedure

  1. Open a secure shell (SSH) connection to any node in the cluster and log in.
  2. Set the snapshot reserve by running the isi snapshot settings modify command with the --reserve option.
    For example, the following command sets the snapshot reserve to 20%:
    isi snapshot settings modify --reserve 20
