I have a single drive that has been in production a while, has production
type stuff on it, and now I want to add a second (identical) drive and
mirror it. I thought I could do this by setting up /etc/raidtab and
/etc/fstab, then doing a raidhotadd.
so if the existing drive is /dev/hde1, the new drive is /dev/hdg1, I could
raidhotadd /dev/hdg1 /dev/md0
Unfortunately, it then tells me it can't find the superblock, and can't
proceed.
Which of course in retrospect makes sens, since it was not set up as a
mirror in the first place.
My question is how can I create a mirrored raid from a non-raid without
having to cpio the whole 150G off somewhere, create the mirror (destroying
everything) and then cpio'ing the 150G back?
tia,
Lee
