Very Computer

Hi there!

I unfortunately installed Linux (RedHat 4.0) on /dev/hdc which means I
can't use LILO.

I would like to "copy" the whole System onto another drive (/dev/hdb)
but I guess I have to change lots of files to get it work - if it will
work at all.

Has someone any experience with this?

Thanks!

Sascha.

Why don't you first ask some search engine like http://www.dejanes.com about
your problem. Your problem has been asked and answered many times
before. Even now there is such a thread going on.

I propose you boot from a rescue disk, so that none of the involved
filesystems gets active. Now mount both disks, perhaps as /mnt (old) oan
/mnt1 (new) Then "cp -a /mnt/* /mnt". To be sure you can to "diff -uwr /mnt
/mnt1 |& tee >diff.log" (tcsh) afterwards.  Check for differences, Mostly
some link which point to nowhere on an inactive disk will be wrong.

!!!!!!!! WARNING !!!!!

!!!!! Don't do that unless you know _exactly_ what you are doing !!!!

The dd command mentioned below is a low-level bitwise copy.
This means it will copy _EVERYTHING_ from /dev/hdc to /dev/hdb.
As these are the whole disks, it will copy the MBR as well as the partition
table as well as any bad blocks.
Imagine the effect, if the target disk is smaller than the source disk.
_ALL_ administration information will think, it's a large disk, but
writing/reading to those sectors behind the physical size will yield
unpredicable results, in the best case only a simple crash, in the worst
case a damaged HD.
If the target HD is larger, the remaining bytes will never be used, because
nothing will know about them (all old information in the partition table
and fs meta data will be overwritten).

Note: It's quite safe to use dd to copy between partitions of exactly the
same size, but don't use it on a HD as a whole.

Boot your new Linux, mount the target partition under something like
/mnt.

Delete all under /mnt.

The cpio command is:

find / | grep -v /mnt | cpio -pdmu /mnt

What this does is uses find as the input to cpio which is in the
passthru mode.  The grep filter keeps the /mnt directory, our target
from reaching cpio, this stops recursion from happening, a VERY BAD
thing!!!!!

Good luck.
