Yes, that is a bug in the (very old) 0.7.2 of Debian. Additionally,
these old versions cannot handle spare devices (after each assemble, you
hae to add them manually). Use at least mdadm 1.4.0, better the newest
(I believe 1.5.0). You do not need to recreate the array, simply stop it
and (re-)assemble it after you have the new mdadm in place - and the bug
and the wrong output is gone.
Had the same problem (that with the spare device) with SuSE 8.2 and
Debian Woody...
Bye, Norman.
