Changing the hostname
 
Hello all,

I have a frontend node and many compute nodes. I want to change the hostname of the nodes across entire cluster. I am planning to use linux specific "hostname" command for this purpose. Is there any special command in ROCK for changing the hostname?

If you are talking about redhat boxes, hostname isn't persistent as far as I know, and you may need to edit /etc/sysconfig/network (I think - from memory). There may be a simpler way though.

Yes billymayday you are right. If change in hostname has to survive a power cycle then I need to do what you suggested but is there any specific command in ROCK that can make my job easy?

Since you have to change the config files, you might want to consider writing a script, if you have a lot of machines to change.
