Hi Everybody,

I was wondering if you could take a look to the following and give some advice... I just
have TWO SATA WD800 disks and "mdadm" says I have "three" and one of
them has "failed"!!!

It's just some odd accounting in the kernel.  Don't worry about it.

I have 8 more raid devices and all of them saying exactly the same. I'm running debian
with 2.4.19 kernel if that helps.

Thanks in advance,

Agustín
