Re: [xcat-user] Custom Entries for hosts or other xcat generated files lost

Hi Brian,

 

Currently, we do not have interface to do that, we plan to discuss this requirements within our team.

 

For makehosts, execute "makehosts" without "-n" will not lose your customized lines.

For makedns, if you want to execute "makedns -n", you should better back up /etc/named.conf, after you execute "makedns -n", you can manually customize /etc/named.conf, then restart named, hope this workaround can work for you now.

 

Best Regards

Subject: [xcat-user] Custom Entries for hosts or other xcat generated files lost
Date: Fri, Jun 1, 2018 6:11 AM
 

Hi,

 

On several occasions we've had the need for xCAT to retain custom information such as external hosts or 'forwarder' entries to the /etc/named file.  These files get generated from tables by commands like 'makehosts' or 'makedns'.

 

The problem is that if the '-n' flag is used with the above commands, it wipes out any custom entries we've added to those files.

 

Example:  in order to properly accommodate for an Isilon Smart connect ip address (used for round robin ip assignment) we had to add a Forwarder stanza to /etc/named.conf

If makedns -n is run (whether on purpose or accident) the entire file gets rebuilt and our custom stanza gets deleted.

 

We had to modify the xCAT perl script that creates the file to append the forwarder stanza from a text file at the end of named whenever the '-n' flag is used with makedns.  

 

Question/Feature request:  Does xCAT have a method to include custom entries to files so that they're not lost if someone runs an xCAT tool with the -n flag (or custom external hosts in /etc/hosts)?
