It is not on my Centos 6.2 system, and doing a little searching through repositories for that specifically, or e4fsprogs, and I can't find it anywhere to even try it. Any google reference seems to point back to resize2fs. I ended up booting a live SystemRescueCD and using GParted via the GUI. My notes indicate that is what I had done previously also. I am still stumped, everything that I have read indicates that resize2fs can do a live resizing on ext4 file systems. Can anybody confirm or deny this? Is the reason I can't do this because it is on an LVM logical volume? Thanks. Jeff Boyce Meridian Environmental
