is just a shortcut for colocation res_Service-IP with res_mount-application colocation res_mount-CIFSshareData with res_Service-IP ... and colocation res_mount-application then res_Service-IP colocation res_Service-IP then res_mount-CIFSshareData ... just re-order and remove any bit you don't need anymore > On 21 Jan 2015, at 3:43 am, Sven Moeller <smoel...@nichthelfer.de> wrote: > > Hi, > > i have a Cluster running on SLES 11 SP3.
