This bz is not related to your issue.

The commands work as expected, user='root' sets the value of 'user' to 
'root', user='' deletes 'user'.

Specifying an empty value for an option is a syntax for removing the 
option. Yes, this means there is no way to set an option to an empty 
string value using pcs.

'pcs resource create' allows setting empty string values. It is a known 
bug which we track and will fix eventually.
