Hi,
I am testing RHCS on Fedora Core 5.
I have a shared gfs volume mounted on two nodes (using clvmd and lock_dlm).
Locally, everything is ok.
If I export the gfs volume via nfs, i obtain *very poor* performance.
For exemple, from a nfs client with dd, it take 90 seconds to create a
16 MB file !!!
From the cluster's nodes, the performances a good, and i made some
tests exporting xfs over nfs, and it was good too.
So what's wrong with nfs+gfs ?
I would be very interested to know how guys who use this have configured
it, and what performances they have.
Thanks for any advices.
Best regards
