RH 6.2 Versus RH 7.2

Wed Jan 30 23:19:27 EST 2002

Extremely important!!  If you're converting the root partition to ext3 and 
you're using a stock RedHat kernel, ext3 is compiled as a module.  After 
setting the line in /etc/fstab to ext3, do: mkinitrd 
/boot/initrd-<version_of_kernel>.img <version_of_kernel>.
for example: if you're using version 2.4.9-21 of the kernel, do: mkinitrd 
/boot/initrd-2.4.9-21.img 2.4.9-21
next, add the following to the section pertaining to the kernel you're 
using.
initrd=/boot/initrd-2.4.9-21.img
Then run lilo and make sure you don't see any errors.  If anything fails, 
you can get out of it by changing the references in fstab back to ext2 
before rebooting.  Also, the command to add the journal is tune2fs.

          HTH.
