Expanding A Root-FS

Dec 01, 2009, 03:02 (0 Talkback[s])

[ Thanks to Falko Timme for this link. ]

"The following tutorial describes, how this is achieved by using Systemrescue-CD. SysRescCD is (as the name says) a kind of minimal Rescue Linux, often used as bootable CD or bootable USB Stick, or also usable as a bootable ISO Image directly in VMware ESX/Server, Virtualbox or similar virtualizers. It has a lot of useful stuff which could be used for maintenance tasks (to be honest, it is NOT minimal as written above).

"Disclaimer

"As installations may differ widely, this tutorial could only be a kind of cooking recipe, a rough guide, and has to be adapted to the concrete setup. This procedure has been developed for a system running as VM under VMware ESX, the root filesystem being LVM2 based ext3, inside a SAN. Operating System was CentOS 5.

"Be careful with all you are doing, all actions are performed with root permission. So make a full backup before you do anything other. You should also be familiar working in a shell. Also do whenever possible "dry-runs" before you do real modifications, and carefully inspect all messages whether they correspond with your expectations."
