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.
