I've installed a two nodes GFS2 cluster on Debian 7. The nodes
are connected to the datas by iSCSI and multipathing with a 10
Gb/s link. I can write a 1g file with dd at 500 Mbytes/s. I
export with NFS (on a 10 Gb/s network) and I only can reach 220
Mbytes/s. I think that it's a little bit far from 500
Mbytes/s...
<br>
<br>
Do you how to tune my settings to increase the speed for NFS ?
<br>
<br>
GFS2 mount :
<br>
/dev/vg-bigfiles/lv-bigfiles /export/bigfiles gfs2
_netdev,nodiratime,noatime 0 0
<br>
<br>
NFS export :
<br>
/export/bigfiles
172.16.0.0/16(fsid=2,rw,async,no_root_squash,no_subtree_check)
<br>
<br>
mount on NFS clients :
<br>
nfs-server:/export/bigfiles /data/bigfiles nfs4
_netdev,rw,user,nodiratime,noatime,intr 0 0
<br>

Use options on NFS clients: rsize=32768,wsize=32768
<br>

Thnaks. I've already tried these settings and it doesn't inscrease
the perfs.<br>
