Resize share
To change file share size, use the manila extend command and the manila shrink command.
For most drivers it 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 manila extend and manila shrink commands
respectively, 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.
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:
$ manila extend docs_resize 2
$ manila show docs_resize
