'man raidctl' suggests that, among other places.  (My personal 
preference is for one filesystem per RAID set.  Search the mail 
archives or on Google for more info..)

For how long, and from what kernel rev(s)?

My guess would be bad RAM, but I might be biased...  (There are NO 
bugs (at least that I'm aware of) in RAIDframe that would be causing 
this sort of lossage.)

You havn't given any config files, but you shouldn't see filesystem 
lossage from any valid RAIDframe configuration (and if a 
configuration isn't valid, RAIDframe shouldn't allow it).
