partitions in meta devices

[Ezra Nugroho]

I am curious if partitioning meta devices is allowed or not.

I just created a software raid array, md0 with 240G logical size.
I want to partition that into two, 100G and the rest.

I used fdisk to create the partitions, and it worked, result:

bangalore exports # fdisk /dev/md0

Command (m for help): p

Disk /dev/md0: 247.0 GB, 247044636672 bytes
2 heads, 4 sectors/track, 60313632 cylinders
Units = cylinders of 8 * 512 = 4096 bytes

    Device Boot    Start       End    Blocks   Id  System
/dev/md0p1             1  24414064  97656254   83  Linux
/dev/md0p2      24414065  60313632 143598272   83  Linux

however, I couldn't create any file system for them, or mount them.
/dev/md0px just don't exist.

Do I need to partition the drives first before creating the raids?
I use devfs instead of file based /dev

Thanks,
