Thanks for all the replies, here's what i did.
I only wanted to have another disk ready for relacing the one on the server in case the disk broke down.
- I mounted the image disk on the second IDE controller as master.
Booted my system normally.
- logged in and with cfdisk and mke2fs partitioned and formated the image disk with the same partitions as the running one (the image disk is smaller but has enought disk space to acommodate the original disk system)
- mounted /dev/hdc (image hd) on /mnt
- did a cp -ax / /mnt
- after the copy, i mounted the image hd (/dev/hdc) as master on the primary contrller.
- booted with debian cd 1, installed lilo on the mbr
- booted the system from the hd (image), check that everything was ok (it was)
- stored the image disk (as backup replacement)
Thank you all for the great tips, a few were quite new to me and are very usefull.
Pete
