Marco, Since you did not mention what resize operation you'd like to do and what file system you run, I will assume you would like to increase(grow) the partition and you are running ext3 FS.
A simple route is to boot the server into bootable linux distro that has GUI "gparted" utility (centos, fedora core or knoppix). You may have to move "swap" partition and other partitions out of the way before you can grow "/" - since the disk space must be allocated consecutively. Alternatively, you can boot into rescue mode and do the same thing via command line, you will have to remove journaling from ext3, grow the FS, fsck, and put journaling back. Good luck -ilya ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Mike Husmann Sent: Monday, January 03, 2011 10:32 AM To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list Subject: Re: [rhelv5-list] Resizing root (no LVM) Hi Marco, On Fri, Dec 24, 2010 at 11:29 AM, Marco Shaw <[email protected]<mailto:[email protected]>> wrote: Hi, I haven't done sys admin in some time, and I just started a new job where I am doing it again. The story before (over 5 years ago) was that you couldn't resize root basically. Now with great stuff like LVM, it seems you can do some resizing from a boot CD and not have to tar/untar and hope for the best... Well, for whatever reason, I have a brand new RHEL5 machine, and they did *not* use LVM. So I guess I'm out of luck with doing a *simple* and "very likely to work" resize of root? Is there free space left on your physical disk? If there is, and you're running a filesystem and a kernel that supports online resizing, you should be able to do it very simply. man resize2fs HTH, Mike
