I don't normally use IDE but I am giving ATA66 a whirl on my workstation. Because of my predominant use of SCSI /dev/sd* is what I am used to dealing with. Of course I meant /dev/hda1 rather than /dev/sda1 > In any case, yes I think that this will > screw up your boot sector.

It's not so much the boot sector I am worried about. What concerns me is that when I set up my new disk (on /dev/hdc1) with LVM, LVM is associating the device /dev/hdc1 with the PV. What happens to that association when I move the disk to the primary ide bus and it becomes /dev/hda1? > I put a (non-LVM) rescue boot partition on my disk which has basically > everything from /bin, /sbin, and some /lib/lib*, /lib/modules/. Everything that is needed for LVM you mean or do you mean you copied everything from your root filesystem? If the latter, would that not be overkill? But I like the idea. I was thinking it was time to move on from emergency boot diskette(s) to a boot CD-ROM. > Cheers, Andreas Thanx Andreas, b. -- Brian J. Murrell
