Uhm, Gabriel --- have you ever looked at the definition of RAID, and
investigated what a RAID is, and how it works? That ought to give you
the explanation as to why your system won't boot when you unplug one
of the RAID drives.
In short, you removed essential data. Unless you run a RAID 5 setup
(minimum of 3 drives needed), the loss of one drive usually results
in an unusable RAID system. That's the very nature of RAID.

Thanks guys for the input. I'll test it out. Another question, if
one of the hard disk failed, can the OS boot normally? Previously I
tested, when I plugged out one of the hard disk, it just can't
boot... I'm not sure why....

Well it removes sendmail and since mdadm depends on mail-client
then it wipes off mdadm also. You could remove sendmail with --
dodeps option or after installing qmail reinstall mdadm (since
qmail provides mail-client dependency) . As far as I know mdadm is
only utility for managing raid devices and software raid will
function without it.
I bet many of us (including me) run mailservers on software raid.

Hi all,
Is it okay that I configure Software Raid with Qmail? I saw in the
dependency checking script that it will actually remove mdadm
packages, am i right?
Please advice.
