-----BEGIN PGP SIGNED MESSAGE----- Hello, >dd could be used for this, provided that the mirror disk was identical in >size/geometry to the source disk. It could be bigger, or have a different Yes the drives are absolutely identical (u2w SCSI: IBM UltraStar 18es) >geometry, but how usable the mirror disk would be in an emergency I don't >know. watch out for the effects of open files though. Can you tell me what parameters I should use with dd? Reading the manual page is think this should be used: dd if=/dev/rda0 of=/dev/rda1 Important assumption: da0 is source, and da1 is destination. I don't want to screw this up, so I am asking ;) ...And what do you mean watch out for effects of open files? Could you explain that one please? (and is there a way to list all open files?)
