Resize share
To change file share size, use manila extend and
manila shrink. For most drivers it is safe operation. In case of
using generic driver it is better to create share snapshot for backup.
You can extend and shrink the share with manila extend and
manila shrink commands correspondingly and specifying the share and new
size that doesn’t exceed the quota. For details, see
Quotas and Limits. You also cannot shrink
size to 0 or to a greater value than the current share size.
While extending the share gets extending status that means that the
increase share size request was issued successfully.
To extend the share and check the result, run:
$ manila extend Share1 2
$ manila show Share1
