MC ServiceGuard control file changes

[Leoanrdo Bowens]

I need to change the mount point order in the /etc/cmcluster/????.cntl file. Do, I simply make a copy of the .cntl file, modify the original file with the changes, stop the package, restart the package and copy the new .cntl file to the other nodes in the cluster?

You just need to change control file and copy it to the remaining nodes.
Next time the package is stopped/started it will use the new configuration.

Hi Leoanrdo,

What you need to do before modifying the control script is

1.) Make a copy of the control file
2.) Edit and make changes to this copy.
3.) Keep another backup copy.
Stop the package
4.) Copy the new control file on all nodes where the pqckage will get activated.
5.) Start the package and test the operations of the package on all nodes.

Hope this helps.

Hi,
You are right, you just have to modify your package control file and copy it on all the nodes and it will be ok. The package will use the new control file at the next start.

In this case, there is no real need to stop the package - if you are confident of your changes. Leave the package up and simply copy your cntl file to the other nodes. If you want to make sure that your changes are correct then halt the package, make the changes, copy the .cntl file to the other node(s), and restart the package. Something this trivial, I wouldn't bother to test just carefully check the changes you made.

Thanks for all of the responses. I think I can handle the task from here.

Hi ,

Go with your plan, copy the cntl file to other nodes just do net forget to create the new mount dir on the other nodes ( check the rights and ownership)
