Nope, doesn't work for me still. It's the root partition I'm trying to resize so if I delete then recreate to larger size, partprobe still fails then if I reboot it won't start as it can't find the root partition. As Barry suggested, I don't think you can reread the root partition. --Russell > -----Original Message----- > From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On > Behalf Of James A.
