I would like to create an (arbitrary) attribute that goes away on cluster shutdown/reboot and from reading the man page for crm_attribute it looks like I should be able to do this at the node level.. however, I can’t seem to get it to work.  I have tried:
> 
>> root at node01:~# crm_attribute -t crm_config --node node01 --lifetime reboot --name leader --update 1
>> root at node01:~# crm_attribute -t crm_config --node node01 --name leader --query
>> scope=crm_config

^^^ this means the second command is looking in the wrong spot.
try adding '--lifetime reboot' to the query command too.
