What ? How ? You lost two drives in your RAID-5 ?

If I'm right in the following, I have a suggestion:
1) Drive 4 died, physically
2) Because of intergalactic interference or whatever, drive 3 has an event count
lower than drives 1 and 2, and therefore the array won't start in degraded mode.
Right ?
If so:
I would guess that you could change drive 4 in the raidtab to be a ``failed-disk'',
and then use --fuckallqueries (you know the right flag ;) to force the array back
online. I *THINK* that would work.
Afterwards, you would raidhotadd the fresh drive 4 to the array, to get redundancy
back up.
This should bring back all your data.
PleasePlease: Before you actually do this, wait for a little while to allow someone
on this list to jump in and say "DON'T!", if appropriate.
