Copying complete root partition (seperate /boot)

Hello!

I want to migrate my root-Partition file system from xfs to ext4. I have a seperate ext2 formatted /boot partition. I created (free space on my disc) a temporary partition to copy all data from the xfs partition and formatted it in ext4.

Now, I want to boot my system from CD mount both partitions and make a complete copy. But which cp parameters are needed?

copy -r /mnt/xfs/* /mnt/ext4_temp ?

Thanks for help!

Best regards,

Flasher

Re: Copying complete root partition (seperate /boot)

mkdir /mnt/root-xfs /mnt/root-ext4
mount /dev/sdaX /mnt/root-xfs
mount /dev/sdaY /mnt/root-ext4
(cd /mnt/root-xfs && tar cf - .) | (cd /mnt/root-ext4 && tar xvpf -)

Then - you must obviously remember to update your /mnt/root-ext4/etc/fstab and also your boot/grub/menu.lst

Re: Copying complete root partition (seperate /boot)

cp -a would work also.  recursive, retains permissions and mod times.
