using webmin to create raid1 mirroring on exsiting system

["harland christofferson" <harland@audubonstrings.com>]

i have a sarge installation.

i have two ide drives (hda and hdc) that are partitioned identically.

when doing the install a while ago, i tried to configure partitions for
raid1 but some how goofed.

i cannot risk losing data on hda while getting raid1 up and running.

has anyone successfully implemented raid1 on an existing system w/ webmin?

has anyone successfully implemented raid1 on an existing system by using
raid tools and mdadm?

i tried to do this on another system years ago ... ended up wiping out
data on hda. i have been skiddish about trying again but have to bite the
bullet now.

regards,
harland
