storage/posix : options to override umask

Options "create-mask" and "create-directory-mask" are added to
remove the mode bits set on a file or directory when its created.
Default value of these options is 0777.

Options "force-create-mode" and "force-create-directory" sets
the default permission for a file or directory irrespective of
the clients umask.
Default value of these options is 0000.

volume set <volume name> storage.<option-name> <value>

The valid value range from 0000 to 0777.
