Small Monitoring Daemon (SMD) does not start on some nodes CMU 7.1

coldfusion — Mon, 28 Apr 2014 13:18:42 GMT

I'm doing some fancy cloning,

we have several clusters, same HW, so I want to reuse the image

from one node to another cluster, same disklayout etc.

I do a dummy install with the right disk partitioning.

Then I replace the image files partachi-sda*.tar.bz2

Deploy image ok, and runs as expected, so far so good, this works fine on a OS level.

But CMU does not like this, the SMD does not start on the nodes.

I can get it to start if I do (in the CMU GUI) Monitoring -> stop then start Monitoring Engine.

But when I reboot a node SMD doesn't start on that node.

Any advice ?

How many nodes do you have in your cluster?

Are all nodes part of network entity ?

Do you mean that every time when you reboot a compute node, you need to restart monitoring to get SMD running on compute node?

did you wait for few minutes after node boots successfully?

Please Increase monitoring debug level CMU_SEC_MONITORING_DEBUG_LEVEL and CMU_SMD_MONITORING_DEBUG_LEVEL to 9 in cmuserver.conf

Restart monitoring daemon, wait for few minutes. Then reboot one compute node, wait for few minutes and check if monitoring starts.

Please check these logs for errors:

On compute where secondary monitoring daemon is running:

/opt/cmu/log/SecondaryServerMonitoring_<hostname>.log

On problematic node:

/opt/cmu/log/SmallMonitoringDaemon_<hostname>.log

/opt/cmu/log/smd_start_<hostname>.log
