I am trying to convert an existing IDE one-disk system to RAID1 using the general strategy found here:
http://lists.centos.org/pipermail/centos/2005-March/003813.html
But I am stuck on one thing - when I went to create the second md device with mdadm,
# mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/hdb2 missing mdadm: error opening /dev/md1: No such file or directory
And indeed, ls /dev/md* shows only md0, which worked fine.
I do have the 'raid1' kernel module loaded.
What am I missing? Do I need to create the nodes manually now?
thanks -S
