serious trouble - raid5 won't assemble properly, vgscan sees no volumes

[Dexter Filmore]

My file server crashed *again* (think there's some harware faulty)
Now at boot time the array is not assembled, I get an I/O error.

/proc/mdstat looks like this:

Personalities : [raid5]
md0 : inactive sda1[0] sdd1[3] sdc1[2]
      732563712 blocks

unused devices: <none>

I am missing something like [UUUU] or so - what's going on here?

Before the server crash I had [U_UU] and vgscan didn't see any volumes.

Re: serious trouble - raid5 won't assemble properly, vgscan sees no volumes - solved

Array is online, degraded for the moment but I can access the file systems for 
backups.

I passed -A --force to mdadm, seems that did the trick. 

What puzzles me still is that I had a degraded array for the third time now 
and never could tell why it happened in the first place.
This time the machine crashed for no apparent reason, tho I suspect heat 
issues. Will investigate and eventually move the disks to another machine.
