Be careful: there are 2 ways of setting up RAID-1 (mirror) for a partitioned disk: • mirror the entire disk, ie sda & sdb • mirror partition by partition, ie sda1 & sdb1; sda2 & sdb2; ... If the second way then unless grub-install is run on both disks then it might only be present on one of them. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.
