Yes, you found a bug. In case the utilization set didn't exist,
no attributes could be set this way. Fixed now.

BTW, you can also use "crm node utilization ..."

> What does 'cibadmin -Q' show for the validate-with attribute of the top-level cib object?  If it's "pacemaker-1.0" then utilization won't work.  I encountered this with a cluster I'd first set up on pacemaker 1.0 (SLES11) and later upgraded to 1.1 (SLES11sp1).

I don't think there's a way to change the validation version from the crm shell.  I may have had to use crm configure edit and add the utilization attributes to the nodes that way, but I did get it working.
