This error from pcs means, that the resource id used with a pcs command
was not found in the CIB.

Either a resource was not created or a resource id was mistyped in a pcs
command.

The `pcs resource create` should error in case resource cannot be
created.

How do you run pcs commands? Manually or by some script? Could you
provide more information like:
* version of pcs
* example of pcs commands used
* cluster configuration (CIB, output of pcs config...)
