I have 2 identical servers with hotswap drives. Having got one configured
(Debian Jessie) and running I want to put one of the drives into the 2nd
server. To do so I presumably need to install GRUB on the drive in the new
server as GRUB isn't RAIDed (using mdadm). Am I correct?

And to do this do I boot from CD and just install GRUB?

I also know I need to delete a file somewhere that has the MAC addresses -
can't remember the file, any clues?


Cheers,

Martin.

I think you meant /etc/udev/rules.d/70-persistent-net.rules (or similar)

Urgh! Grub. Even with MD RAID disks I would expect the entire disk to be
cloned . . . unless you're only doing RAID on certain partitions. Try
sticking the disk in and see what happens! Otherwise, yes, you could
boot off a CD and install Grub however it's usually not as simple as
that because you'll need to mount the boot partition of your system disk
and use that configuration when installing Grub so Grub knows where
everything is. I'm sure there's instructions online somewhere. I need to
do it so infrequently I don't retain the knowledge in my brain. :-)

In Debian MAC addresses get put into
/etc/udev/rules.d/70-persistent-net.rules. When you move the disk to the
other machine the new Ethernet interface will show up as eth1 unless you
delete the old interface from that file.

Shane.

You'll either need to use ChrUbuntu for a native boot, or Crouton for live
switching (via a chroot).

There's lots of information on the web regarding both of these methods.
