mkraid aborted - device too small??

[Alex H. Vandenham]

mkraid fails complaining about the device being too small.  Here's the details;

Using raidtools-0.50beta3 and 2.0.38 kernel with

/etc/raidtab;

raiddev /dev/md2
        raid-level      1
        nr-raid-disks   2
        nr-spare-disks  0
        chunk-size      128

        device          /dev/hda8
        raid-disk       0
        device          /dev/hdc8
        raid-disk       1

and fdisk -l shows;

/dev/hda8 as 514048 blocks
/dev/hdc8 as 514048 blocks

when I use;

mkraid -f  /dev/md2

I get;

handling MD device /dev/md2
analysing super-block
/dev/hda8: device too small (0kB)
mkraid aborted

Please note I have good reasons to use this combination of kernel and tools and
that using exactly the same procedure, md0 and md1 were created with no
problems.

Any suggestions???????

TIA
