Thanks mate, what you say makes sense. Anyway I`m dealing with different
file sizes, varying from KBs to GBs. Luckily some of the files are grouped
in folders, for example in folder /fs/X all files will be 9MB, which I`ll
not stripe. In /fs/Y all files will be GBs, which I`ll stripe among all
OSTs.
With a 1MB default stripe size, anything that is <1 MB is a "small" file. In
general, I would not stripe 10MB files across more than one OST (each).

Dear list,
We're currently experimenting with Lustre and small files (<=1MB)
and some questions came to mind:
- will writing files that are smaller than the stripe_size and that
are written to a fully striped directory create objects on more
than 1 OST?
- what would be the main options to t
