You might also try gparted live cd (http://gparted.sourceforge.net/livecd.php). You can resize partitions using a GUI. The live cd seems to support most RAID controlers as well. v/r angelo -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Ryan Golhar Sent: Monday, September 29, 2008 10:30 To: General Red Hat Linux discussion list Subject: Re: resizing swap In case, anyone is interested in the the solution... You can't shrink a volume using resize2fs so rebooting into single user mode and mounting / as read-only won't work. After some more googling, I found the following: 1. Write the FC rescue disk ISO onto a CD, and reboot the machine from it. 2. Do not mount the file systems. 3. At the prompt, type: lvm 4. Within LVM, run these commands (comments are after the '#'s): lvm> vgscan # Will show the name of the Volume Group vgchange lvm> --available y VolGroup00 # Activates the VG and the LVs in it lvm> lvscan # Should show the LVs as "ACTIVE"; the devices in /dev it mentions should now exist lvm> exit # Quit, return to the prompt 5. Now resize the filesystem with this command (e.g., using device /dev/VolGoup00/LogVol00): e2fsck -f /dev/VolGoup00/LogVol00 # fsck on the filesystem resize2fs /dev/VolGoup00/LogVol00 nnG # resize the fs to nn GB; nn should be less than the current fs size e2fsck -f /dev/VolGoup00/LogVol00 # Do another fsck on the filesystem; fix any errors which appear 6. Run lvm again and type: lvm> lvreduce -LnnG /dev/VolGoup00/LogVol00 # Resize the LV to nn GB; nn should be the same as above lvm> exit # Quit, return to the prompt 7. Finally, do another filesystem check: e2fsck -f /dev/VolGoup00/LogVol00 # Do another fsck on the filesystem; fix any errors which appear 8. Remove the CD and reboot.
