-- Delete a metadata key-value pair.
command allows the user (or a script) to modify the
metadata for a guest instance running in a SmartDataCenter (SDC)
Metadata values are generally set programmatically via CloudAPI
during interactive provisioning via a Web Portal. They may also be set from
within the instance with the mdata-put
The key-value pair for keyname
will be removed permanently from the
metadata stored for this guest instance. Deletion of a key which did not exist
is not considered an error.
If the metadata service is unavailable at the time of the request, this command
will block waiting for it to become available. Non-transient failures will
cause the program to exit with a non-zero status. Depending on the nature of
the error, some diagnostic output may be printed to stderr
The following exit values are returned:
The key-value pair named keyname
was removed from the instance metadata,
or did not initially exist.
An error occurred.
An unexpected error condition occurred, which is believed to be a non-transient
condition. Retrying the request is not expected to resolve the error
condition; either a software bug or misconfiguration exists.
A usage error occurred.
Malformed arguments were passed to the program. Check the usage instructions to
ensure valid arguments are supplied.
