.. -*- rst -*- ====== Shares ====== A share is a remote, mountable file system. In the APIs below, a share resource is a representation of this remote file system within the Shared File Systems service. This resource representation includes useful metadata, communicating the characteristics of the remote file system as determined by the user and the Shared File Systems service. You can create a share and associate it with a network, list shares, and show information for, update, and delete a share. To create a share, specify one of these supported protocols: - ``NFS``. Network File System (NFS). - ``CIFS``. Common Internet File System (CIFS). - ``GLUSTERFS``. Gluster file system (GlusterFS). - ``HDFS``. Hadoop Distributed File System (HDFS). - ``CEPHFS``. Ceph File System (CephFS). - ``MAPRFS``. MapR File System (MAPRFS). You can also create snapshots of shares. To create a snapshot, you specify the ID of the share that you want to snapshot. A share has one of these status values: **Share statuses** +----------------------------------------+--------------------------------------------------------+ | Status | Description | +----------------------------------------+--------------------------------------------------------+ | ``creating`` | The share is being created. | +----------------------------------------+--------------------------------------------------------+ | ``creating_from_snapshot`` | The share is being created from a parent snapshot. | +----------------------------------------+--------------------------------------------------------+ | ``deleting`` | The share is being deleted. | +----------------------------------------+--------------------------------------------------------+ | ``deleted`` | The share was deleted. | +----------------------------------------+--------------------------------------------------------+ | ``error`` | An error occurred during share creation. | +----------------------------------------+--------------------------------------------------------+ | ``error_deleting`` | An error occurred during share deletion. | +----------------------------------------+--------------------------------------------------------+ | ``available`` | The share is ready to use. | +----------------------------------------+--------------------------------------------------------+ | ``inactive`` | The share is inactive. | +----------------------------------------+--------------------------------------------------------+ | ``manage_starting`` | Share manage started. | +----------------------------------------+--------------------------------------------------------+ | ``manage_error`` | Share manage failed. | +----------------------------------------+--------------------------------------------------------+ | ``unmanage_starting`` | Share unmanage started. | +----------------------------------------+--------------------------------------------------------+ | ``unmanage_error`` | Share cannot be unmanaged. | +----------------------------------------+--------------------------------------------------------+ | ``unmanaged`` | Share was unmanaged. | +----------------------------------------+--------------------------------------------------------+ | ``extending`` | The extend, or increase, share size request was issued | | | successfully. | +----------------------------------------+--------------------------------------------------------+ | ``extending_error`` | Extend share failed. | +----------------------------------------+--------------------------------------------------------+ | ``shrinking`` | Share is being shrunk. | +----------------------------------------+--------------------------------------------------------+ | ``shrinking_error`` | Failed to update quota on share shrinking. | +----------------------------------------+--------------------------------------------------------+ | ``shrinking_possible_data_loss_error`` | Shrink share failed due to possible data loss. | +----------------------------------------+--------------------------------------------------------+ | ``migrating`` | Share is currently migrating. | +----------------------------------------+--------------------------------------------------------+ | ``migrating_to`` | Share is a migration destination. | +----------------------------------------+--------------------------------------------------------+ | ``replication_change`` | The share is undergoing a replication change. | +----------------------------------------+--------------------------------------------------------+ | ``reverting`` | Share is being reverted to a snapshot. | +----------------------------------------+--------------------------------------------------------+ | ``reverting_error`` | Share revert to snapshot failed. | +----------------------------------------+--------------------------------------------------------+ List shares =========== .. rest_method:: GET /v2/{project_id}/shares Lists all shares.
