Not-fresh + failure

Not-fresh + failure

[Titus Winters]

Please help my poor file server: 

I've got 4 scsi drives on two controllers running RAID-5 in software.

So as near as I can tell I've got one drive that failed and cut off 
communications with the other disk on the SCSI controller (or something)
which made that second drive become not-fresh before the kernel panicked.

dmseg says that one is not-fresh, and the other is faulty.  How do I
proceed without data loss?  I've tried raidhotadd to bring up the 
not-fresh drive, but the raid device can't start up and thus I can't 
hot add it.  

Thank you very much

My apologies for asking a question that was in the FAQ.  I thought the
not-fresh attribute was perhaps recoverable with something less scary
than mkraid --force.  Turns out this was the correct solution, and
my data is recovered, safe and sound.  Thank you very much.
