Why? I can't see the point in making 1 240Gb filesystem.

Ok, understand this.

Looks like raidtools v0.9 and an _old_ md.
I think paching the kernel should work.

This is kind of normal. RH disto's and alike scan's
youre /etc/ dir and preform's all kind of unholy things :-)
(I should know M working with Mandrake here :-)
I suggest you patch your kernel...
