nodes.<br>However, this "...another node is heartbeating in our slot!" warning on the node2 just drives me crazy.<br><br>Could somebody please help me to either turn it off or explain what is wrong.<br><br>Many thanks in advance,<br><br>Alex<br><br>messages in /var/log/warn<br><------------ snipped --------------><br><br>Jan 26 13:50:31 node2 kernel: [ 2740.959848] OCFS2 Node Manager 1.5.0<br>Jan 26 13:50:31 node2 kernel: [ 2740.961868] OCFS2 DLM 1.5.0<br>Jan 26 13:50:31 node2 kernel: [ 2740.962625] ocfs2: Registered cluster interface o2cb<br>Jan 26 13:50:31 node2 kernel: [ 2740.974260] OCFS2 DLMFS 1.5.0<br>Jan 26 13:50:31 node2 kernel: [ 2740.974331] OCFS2 User DLM kernel interface loaded<br>Jan 26 13:50:44 node2 kernel: [ 2753.748066] OCFS2 1.5.0<br>Jan 26 13:50:44 node2 kernel: [ 2753.757040] ocfs2_dlm: Nodes in domain ("8B9FFC5A4F12408EA5FC14B7CD1B3E97"): 2<br>Jan 26 13:50:44 node2 kernel: [ 2753.821386] ocfs2: Mounting device (147,0) on (node
