We have moved as many files to a nfs server as we could so simply. The system has been heavily modified (all using rpms) from baseline. What is the most practical method to replace the hard drive?Install another drive (same size or larger), boot from CD in rescue mode and use the dd utility to copy the old drive image to the new disk (example: dd if=/dev/hda of=/dev/hdb). However, the failing hardware could make this problematic. Then remove the dying disk and install the new disk on the cable where the old disk was so that the new disk is now /dev/hda.Tried this, I should have been more clear above. When I access certain sectors the machine reboots. Ideas on how to do the duplication in this scenario?If you are lucky enough to succeed consider mirroring with Linux software RAID or at least make a full backup.
Did you try ddrescue? http://www.gnu.org/software/ddrescue/ddrescue.html -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!!
