Instead of unmounting the partition try using 'mount -o rw,remount ....', I dont use the live CD much, but unless you screwup the rw, remount, or the path to the mounted partition it should either remount the partition properly or error that you didnt point to the correct path. I have rarely had issues with remount so it sounds like it would get around your issue. -- Trevor Benson dCAP, LPIC-1, CLA, Network+, MCP, CNA A1 Networks - Network Engineer DID (707)703-1041 FAX (707)703-1983 On Jun 30, 2010, at 4:43 PM, drew einhorn wrote: > Hi, > > I'm trying to repair a remote system using the Live CD. > I have VPN access to the subnet where it lives. > > An onsite person is booting from cd, and running a small script I > provided to tweak the default firewall rule set to allow incoming ssh, > and set a password for the centos user and start sshd > > so far so good I can remotely access the system. > > the problem is the live cd environment is very fragile. > > I need to rebuild the contents of a couple filesystems, > so I need to umount them and remount them rw. > > If I make a mistake in a mount command instead of giving > an error message and letting me try again.
