Hi,

Thanks to Michael Schneider for his quick response.  Creating soft
partitions on top of a mirror meta device is possible using disk suite.
 For example :

<metastat>
d5: Mirror
    Submirror 0: d15
      State: Okay
    Submirror 1: d25
      State: Okay
    Pass: 1
    Read option: roundrobin (default)
    Write option: parallel (default)
    Size: 6349824 blocks (50.0 GB)

d15: Submirror of d5
    State: Okay
    Size: 6349824 blocks (50.0 GB)
    Stripe 0:
        Device     Start Block  Dbase        State Reloc Hot Spare
        c1t0d0s5          0     No            Okay   Yes


d25: Submirror of d5
    State: Okay
    Size: 6349824 blocks (50.0 GB)
    Stripe 0:
        Device     Start Block  Dbase        State Reloc Hot Spare
        c1t1d0s5          0     No            Okay   Yes
</metastat>

# metainit d19 -p d5 10gb
# metainit d29 -p d5 10gb
# metainit d39 -p d5 10gb
# metainit d49 -p d5 10gb
# metainit d59 -p d5 10gb

Thanks,

Alex.
