When I installed SL4.0 it created one logical volume for / which is not suitable for a production environment. Instead of reinstalling I wanted to try to resize the volume so I could create new volumes in the volume group instead. The main issue I ran into was that resize2fs is not in e2fsprogs-1.35-11.6.EL4 (its in e2fsprogs-1.32-15.1 on my 3.x machines). Don't know why. Steps to follow (I resized / to 8G): BACKUP! download and build http://e2fsprogs.sourceforge.net/ boot from cdrom to rescue mode (choose not to mount) lvm vgchange -ay mount /dev/VolGroup00/.. /somewhere copy the resize2fs binary from /somewhere unmount /somewhere e2fsck -f -v /dev/VolGroup00/.. resize2fs /dev/VolGroup00/.. 8G lvm lvreduce -L 8G /dev/VolGroup00/.. e2fsck -f -v /dev/VolGroup00/.. (to be sure) Done, now you can create volumes with lvcreate. Joakim
