Creating Raid with already installed Archlinux os

Grettings !

I need to know if it's possible to install/configure a software raid in an already operationnal archlinux server.

The server is a Virtualbox server configured with only one disk. I need to plug another disk, construct a raid1 without loosing any data.

I need to apply this raid1 on /home partition.

Any way to do this ? any suggestion ?

Re: Creating Raid with already installed Archlinux os

You can create a raid1 with your new disk and a second "dummy" disk called "missing". Then copy your data into this "degraded" mirror. Once it's all copied, add your original /home to the mirror as if it were the replacement for the "missing" disk.

Of course, you will feel much better about doing this if you have a backup of this data before you try it.

Re: Creating Raid with already installed Archlinux os

if this works out maybe you could postback a detialed howto or create a wiki entry.  i'd be interested in doing this but i've never done anything raid related and it's kind of intimidating to me
