Today,I have recompile kernel 2.6.24 with reiserfs support with Module on rhel5.then I make following change:
1:change /etc/fstab:
/dev/Vg1/lv.root / reiserfs defaults 1 1
and cd /boot/; mkinitrd --with=reiserfs initrd-reiserfs-2.6.24.img. 2.6.24
2:then I use other support reiserfs os enter rescue mode.
commands:
mkdir /source;lvm vgchange -a y Vg1;mount /dev/Vg1/lv.root /source;mkdir /backup;mount /dev/sda6 /backup;
cd /source;tar cvzf /backup/rhel5.tgz *;umount /source;
mkreiserfs /dev/Vg1/lv.root;mount /dev/Vg1/lv.root /source;
cd /source;tar xvzf /backup/rhel5.tgz.then reboot with 2.6.24.
