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,
What kind of server are you using?
Sorry for late response.
Fedora14 + 3.1.0-rc8-pnfs
And you're exporting gfs2?
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?
I'm using spnfs.
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.
Got it.
I will keep on investigating the issue.

So, you're the expert.
