When I wrote the luste HA guide 

https://wiki.hpdd.intel.com/display/PUB/Using+Pacemaker+with+a+Lustre+File+System

I think I had to add "luste" to the list of $FSTYPE in the resource agent. The 
guide is a little out of date, since basically it is from 2010 or so. Please 
check if everything described there works in a modern pacemaker installation.
