Carlos Eduardo a0f3a36b10 Updates the share extend and shrink documentation
The share extend and shrink documentation was still using the
manila client, so the examples were now updated to match the
command in OSC.

Resize share

For most drivers, resizing the share is safe operation. If you want to be sure that your data is safe, you can make a share back up by creating a snapshot of it.

You can extend and shrink the share with the openstack share resize command, and specify the share with the new size that does not exceed the quota. For details, see Quotas and Limits <shared_file_systems_quotas>. You also cannot shrink share size to 0 or to a greater value than the current share size.

Note

From API version 2.53, extending a replicated share, manila quota system will reserve and consume resources for two additional quotas: share_replicas and replica_gigabytes. This request will fail if there is no available quotas to extend the share and all of its share replicas.

While extending, the share has an extending status. This means that the increase share size request was issued successfully.

To extend the share and check the result, run:

$ openstack share resize docs_resize 2
$ openstack share show docs_resize
