Deon,

Thanks!

So what would that mean - that the MooseFS looses files it can not properly
write to the underlying file system? If that is the case is there a way to
fight that problem? Can we, for instance, tell it to retry a certain number
of times?

Anybody know if there are relevant settings - and if so, where they would
be?

Boris.
