Shares
======
A share is a remote, mountable file system. You can mount a share
to and access a share from several hosts by several users at a
time.
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).
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. |
+----------------------------------------+--------------------------------------------------------+
| ``deleting`` | The share is being deleted. |
+----------------------------------------+--------------------------------------------------------+
| ``error`` | An error occurred during share creation. |
+----------------------------------------+--------------------------------------------------------+
| ``error_deleting`` | An error occurred during share deletion. |
+----------------------------------------+--------------------------------------------------------+
| ``available`` | The share is ready to use. |
+----------------------------------------+--------------------------------------------------------+
| ``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. |
+----------------------------------------+--------------------------------------------------------+
| ``reverting`` | Share is being reverted to a snapshot. |
+----------------------------------------+--------------------------------------------------------+
| ``reverting_error`` | Share revert to snapshot failed. |
+----------------------------------------+--------------------------------------------------------+
