Dear Debian Users,
I currently have a NAS server running Debian Linux with kernel 2.4.22 with XFS filesystem.
The NAS currently has 1.5 gigs of Memory and is a Dual Pentium III 1.4 gigahertz machine.
I have 4 machines that mount this NAS for e-mail/pop services. The mail servers are normally
under very heavy loads and I notice that the load on the NAS skyrockets causing lots of issues
with pop3. I am almost positive it is NFS issues and am trying to figure out how to better tune
the NFS on my NAS so i have less issues.
I am using the nfs-kernel-server and I have in my /etc/defaults/nfs-kernel-server
# Number of servers to start up RPCNFSDCOUNT=300
My /proc/net/rpc/nfsd shows:
th 300 6328317 437895.770 181412.220 96134.190 58149.750 38388.700 27054.990 20005.880 15421.700 12464.920 21369.570
My clients mount the NAS server using NFS options: rsize=8192,wsize=8192,timeo=14,lock,intr,rw
Anyone who can give me any information on what I can do to get better performance on the NAS and
hopefully end my NFS issues would be greatly appreciated.
