Hello, my setup is in a 30GB partition with LVM on top. now i had something like the following initially set up / 1GB /home 3GB and a few other non standard mountpoints ok i found that although this is just some minimal system for testing the / partition is to small (more precise /usr is eating up too much space) so I set up a new LV for /usr rsynced mounted and modified fstab to fit the changes. of course I'd like to regain the space that the /usr directory on the / partition uses. Could I just "telinit 1" umount the /usr mountpoint empty out the /usr directory remount again and telinit 3 back to normal? thanks for the help
I'd suggest booting from a rescue or live CD, mount your system disk root on /mnt and delete contents of /mnt/usr.
On reboot, all should be well.There's no guarantee that going down to state 1 will in fact kill off every process that has something open in the /usr directory. In theory, it should, and what you suggest should work, but I've seen a number of cases where this doesn't happen, completely.
Besides, there are a lot of programs in /usr/bin that could turn out to be useful, and using the CD will provide them.
