Hello,
I've installed a two nodes GFS2 cluster on Debian 7.
What kernel is that?
3.2.0-4-amd64
--b.
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...
Do you how to tune my settings to increase the speed for NFS ?
GFS2 mount :
/dev/vg-bigfiles/lv-bigfiles /export/bigfiles gfs2
_netdev,nodiratime,noatime 0 0
NFS export :
/export/bigfiles
172.16.0.0/16(fsid=2,rw,async,no_root_squash,no_subtree_check)
mount on NFS clients :
nfs-server:/export/bigfiles /data/bigfiles nfs4
_netdev,rw,user,nodiratime,noatime,intr 0 0
