Sometimes I find myself wondering how big an installed RPM's files really are. Use a simple script to do all of the calculating of file sizes, plus see how to recreate the RPM from the system where the package is installed in the latest addition to Linux Just Does That.

Last week I was asked if there was a way to start an application at the command line and later come back to it from somewhere else. Normally in Linux/Unix (*nix) it is possible to 'background' a process and then return to it later on but that's only if you are still in the same session where the process was sent to the background. This is useful to have something run while you do other things but reconnecting to this session cannot be done with just the shell. Thankfully 'screen' is on Linux systems by default (all of them I've used anyway) and as a result, Linux Just Does That.

Every day it seems I find something new that Linux Just Does. Last week I finally decided I needed to learn about "shared storage" and started asking the resident experts here, who all pointed me to YaST. Much to my surprise iSCSI is built into YaST and works out of the box with SLES without much more than ten minutes and an understanding of the technology. For the quickest understanding of shared storage I can muster this article is now being created. Hopefully it will be as enlightening to others as this topic was to me.

Want to make sure you have a full copy of all volume trustee and IRF's on a per volume basis before beginning your migration to OES2 SLES? I did and this is what I came up with....
