Good morning all,

I am playing around with overstriping a bit and I found a behavior that, to me, would seem unexpected.  The documentation for -C -1  indicates that the file should be striped over all available OSTs.  The pool, which happens to be the default, is ssd-pool which has 32 OSTs.  I got a stripeCount of 2000.  Is this as expected?

pfe20.jbauer2 214> lfs setstripe -C -1 /nobackup/jbauer2/ddd.dat
pfe20.jbauer2 215> lfs getstripe /nobackup/jbauer2/ddd.dat
