Re: drive mirroring

Back when I was trying to do drive mirroring with software (on linux)
you could not mirror the root partition, I don't remember why now, but I
fought with it for quite some time (and some experimental kernels)
before giving up, I would suggest using hardware raid and then doing a
backup of your original and restoring to your raid device (assuming this
is a business situation and you have an extra hard drive), just a couple
of thoughts

Subject: drive mirroring

any easy way to force mirroring on a drive?

here is the current setup

2 identical 40 gig drives

/hda1 is /boot
/hda2 is swap
/hda3 is /var
/hda4 is /

/hdb is clean

i want /hdb to be a full mirror of /hda

any easy way to go about setting up mirroring without loosing anything?

the stuff i have found on raid on linux seems to imply that you have to
set
up the mirroring before any data is put on the partition

i want full drive mirroring but dont want to loose any data :\
