[Lustre-discuss] upgrade to 1.7.2 or 1.8.1

[Patricia Santos Marco]

Thanks for the quick reply, Then, the best choose is upgrade to 1.8.1. And,
another question. The I/O tools and scripts can not run in production
because the write tests are destrutive, so, Are there some test ( not
destructive) to prove the best number of  threads in the OSSs?
