When copy a big file(about 500MB) to nfs server using pnfs, it cost
obvious longer time as compared with NFSv3 or NFSv4 protocol.
PNFS cost about 300-550s
NFSv3 cost about 49s
NFSv4 cost about 49s
My test environment as following:
MDS: 3.1.0-rc8-pnfs ipaddr1: 192.168.0.100, ipaddr2:192.168.1.100
DS1: 3.1.0-rc8-pnfs ipaddr1: 192.168.0.101, ipaddr2:192.168.1.101
DS2: 3.1.0-rc8-pnfs ipaddr1: 192.168.0.102, ipaddr2:192.168.1.102
client: RHEL6.2GA(2.6.32-220.el6.i686) ipaddr1: 192.168.0.19,
ipaddr2:192.168.1.19
192.168.1.100 <-------- NFS4.1 connection --------->192.168.1.101
192.168.0.100 <-------- NFS4.1 connection --------->192.168.0.102
192.168.0.19 <-------- NFS4.1 connection --------->192.168.0.100
Dunring the write process, the client output the message:
FS-Cache: Loaded
FS-Cache: Netfs 'nfs' registered for caching
nfs4filelayout_init: NFSv4 File Layout Driver Registering...
nfs: server 192.168.1.101 not responding, timed out
The message "nfs: server 192.168.1.101 not responding, timed out" was
output during the COMMIT request.
Who can tell me the reason why pnfs cost so long time.

No. I'm exporting ext4.
Does the file system type would influence the result?

So you're using local-pnfs? Or spnfs? What setup instructions did you
follow?

OK, got it.
I'm not sure if anyone here can talk about the performance of spnfs.
It's not really maintained as far as I know.
So, you're the expert.
