Overview

  • While the writable snapshots feature does not have its own specific license, its use is governed by the OneFS SnapshotIQ data service. As such, in addition to a general OneFS license, SnapshotIQ must be licensed across all the nodes in order to use writable snapshots on a PowerScale cluster running OneFS 9.3 or later. Also, the ‘ISI_PRIV_SNAPSHOT’ role-based administration privilege is required on any cluster administration account that will create and manage writable snapshots. For example:

    # isi auth roles view SystemAdmin | grep -i snap

                 ID: ISI_PRIV_SNAPSHOT

    More information about OneFS roles-based administration and access control is available in the document Access Control Lists on Dell PowerScale OneFS.
