Dear all,
We have an IBM cluster with 44 compute nodes.
I had to reinstall them for different reason. This went ok except for only one
node (node11).
Once I submitted the commands to prepare the node for reinstallation, it boots
correctly, I think it gets its IP address according to the messages in the
console, but does not respond to the ping. And nothing. It gets stuck. I cannot
find anything in the logs (/var/log/messages from the mn). Tcpdump seems to
have traffic with this node:
# tcpdump –i eth2
14:27:18.536865 IP aries.53291 > node11-bmc.7578: . ack 1494861 win 126
14:27:18.610937 IP node11-bmc.7578 > aries.53291: P 1494861:1494870(9) ack 1122
win 2920
14:27:18.610992 IP node11-bmc.7578 > aries.53291: P 1494870:1494889(19) ack
