J'ai fait :
- bind
- bugzilla
- ethercalc2
- etherpad
- liberte0
- mail2
- proxy2 

Attention, dans le lot :
- certaines sont deja eteintes et pas filtrés par ma commande
- certaines ne sont pas sur du glusterfs mais directement dans le /var
  de troll3 et pour celle la, va falloir la jouer autrement ( ie,
  -umount +rm dir/* ) ;)
