When trying to modify Logical Volume or resizing it for example, the system print the following error: 
LV is already locked with incompatible mode
The Volume Group is being managed by cluster software "pacemaker" and has the following resource definition:
primitive vg-data LVM-activate \
        params vgname=vg-data vg_access_mode=lvmlockd activation_mode=shared
And the Logical Volume have the following resource definition:
primitive lv01 Filesystem \
	params device="/dev/vg-data/lv01" directory="/my-data" fstype=ext4 


To fix the problem the right activation_mode should be used based on the LV's filesystem.
  • In case the FS is xfs or ext4 activation_mode should be exclusive 
  • In case gfs2 and ocfs2 activation_mode should be shared 
 Note: default value is exclusive. For more information check: crm ra info LVM-activate


Wrong activateion_mode used in LVM-activate resource definition.
