[ClusterLabs] resource lvm ok but subsequent mount fails

[lejeczek]

hi there

I've had a working set of resources but now mount fails.
here:
$ pcs constraint show
..
Colocation Constraints:
   Resource Sets:
     set aLocalStorage5 aLocalStorage5mnt smartd smb nmb 
setoptions score=INFINITY

pretty basic, no groups, no ordering constrains.
It was working but now even though aLocalStorage5(lvm) 
succeeds the aLocalStorage5mnt fails(saying something that 
device is not there)
I do resource cleanup and instantly all good, resources pick 
up and start.

Where to start troubleshooting/tweaking?
many thanks, L.
