How do convert my root file system from ext2 to ext3 without rebooting?

Tentative notes for converting / from ext2 to ext3 while booted on /:

Unmount everything (including /proc ...)

tune2fs -Ohas_journal /dev/cciss/c0d0p3

(assuming c0d0p3 is your root partition)

mount -t ext3 -o remount,rw / /

Change the root entry in /etc/fstab

mount -a
