problem with creating raid1

Hi,

I was following the Convert a single drive system to RAID guide to convert my single disk install to a raid1.

While copying and pasting commands I inadvertently created an ext3 RAID1 with the following command:

sudo mkfs -t ext3 -j -L RAID-ONE /dev/md0

Problem is that I wanted to create an ext4 RAID1. Having no experience with raids and mdam my question is: How to convert it to ext4?

Can I just repartition the disk and start afresh?

Re: problem with creating raid1

Okay, I HOPE this is solved (haven't marked it as such though as I'm not sure). After a little nap I simply did:

sudo mkfs -t ext4 -j -L RAID-ONE /dev/md0

and got:

toad@deskarch 1016\22 ~ > sudo cat /proc/mdstat
Password: 
Personalities : [raid1] 
md0 : active raid1 sdb2[1]
      48828471 blocks super 1.2 [2/1] [_U]
      
unused devices: <none>
