I am working on a multi-server system for a client. All of the servers are fresh installs (although two were installed a couple of months ago, five a couple of days ago).
They are all supposed to be the same version of everything, but when I uname -a the two that were installed originally have
3.2.0-36-generic #57-Ubuntu SMP GNU/Linux
and the five new ones have
3.2.0-29-generic #46-Ubuntu SMP GNU/Linux
I have done apt-get upgrade on all servers, but this doesn't change. Is it a big deal? The servers will be a replicated mysql setup and the mysql version is the same on all of them.
Is it easy (or worthwhile) to upgrade the #46 to #57 so they are the same through and through? They are the same hardware. Can you point me to some guides as to how to do this upgrade?
