Re: [Gluster-users] Kernel NFS on GlusterFS

2018-03-07 Thread Ondrej Valousek
You say that accessing Gluster via NFS is actually faster than native (fuse) client? Still I would like to know why we can’t use kernel NFS server on the data bricks. I understand we can’t use it on MDS as it can’t support pNFS. Ondrej From: gluster-users-boun...@gluster.org

Hi list, I am wondering why do we need Ganesha user-land NFS server in order to get pNFS working? I understand Ganesha is necessary on the MDS, but standard kernel based NFS server should be sufficient on DS bricks (which should bring us additional performance), right? Could someone clarify?

Hi, As I posted in my previous emails - glusterfs can never match NFS (especially async one) performance of small files/latency. That's given by the design. Nothing you can do about it. Ondrej -Original Message- From: gluster-users-boun...@gluster.org
