Don't modify anything on the old disk, just in the new one!!! What are the 500 MB partitions for? Well It does not matters, but I will use them in this example. I always do this on my laptops. Make identical (size) volumes on LVM in the new disk as many partitions you have on the old disk. Now reboot with debian live cd or usb stick and bring up LVM or... do all of this without reboot directly from your current system running but stop as many services as you can. Then supossing your old disk is: old disk: sda1=/boot (1GB), sda2=swap (9GB), sda3=/ (30GB) You must configure your new disk similar to this: new disk: sdb1=/boot (500M), sdb2=none (500M), sdb3=lvm=rest(999GB). In lvm at vg00 you must create: lvswap (9GB), lvroot (30GB). Then use the command dd to copy each partition... one by one... byte by byte: dd if=/dev/sda3 of=/dev/vg00/lvroot The same with /dev/sda1 and all the none swap partions of your old disk. Later copy the boot sector with GRUB: dd if=/dev/sda of=/dev/sdb bs=512 count=1 You must mount and edit the /boot/grub/menu.lst and /boot/grub/device.maps in the NEW DISK to fit the new hardware names... adjust sda to sdb. Disconnect the old disk and boot from new one installed as master on your mother board. Done! If anything fails you always can start all over again your old disk is save. -- - You don't know where your shadow will fall, Somebody.- - Ing.

Re: Best way to migrate disks
You are probably asking a more subtle question that I'm going to answer but ... As far as the root partition itself, just make a new file system in the partition you want to be the new boot and use tar to copy the old root over. Make sure you don't copy anything mounted on root - just root itself. Then edit fstab in the obvious way to account for the new UUID of the new root. Assumine LILO can boot from the partition on the larger disk, fix lilo.conf in the obvious way, run lilo, and remember to make the new root partion bootable. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

I found several sites advocating piping the results of find to cpio and this worked perfectly. All I had to do after that was to add a new stanza to lilo.conf and update fstab in the new partition, then run lilo. Works like a charm.
