[gpfsug-discuss] Not recommended, but why not?

[Skylar Thompson]

Our experience is that CES (at least NFS/ganesha) can easily consume all of
the CPU resources on a system. If you're running it on the same hardware as
your NSD services, then you risk delaying native GPFS I/O requests as well.
We haven't found a great way to limit the amount of resources that NFS/ganesha
can use, though maybe in the future it could be put in a cgroup since
it's all user-space?
