Interesting. I booted up in runlevel 3 thinking that would prevent anything from from interfering with the umount. Based on a note from Sunny, sounds like I need to boot from the installation DVD in order to be able to unmount the file system. >> I'm thinking that I should be trying to unmount the >> filesystem itself, not the device, >There's no real difference when it comes to using the "umount" command. >It will look up a mount-point directory in /etc/mtab and translate it >to the name of the device mounted there for you, so you can use either >to accomplish an unmount operation. So I guess there was nothing wrong with umount /dev/hda2, it was simply unmountable, so to speak, for other reasons. >> but don't know how to figure out >> what that is (and I can't remember a command that would show the >> filesystem name associated with the device). >The "mount" command shows which device is mounted on which mount point >(a directory).
