I'm testing a two nodes glusterfs distributed cluster (version
3.3.1-1)
<br>
on Debian 7. The two nodes write on the same iscsi volume on a
SAN.

When I try to write an 1G file with dd, I have the following
results :
<br>
<br>
NFS : 107 Mbytes/s
<br>
Gluster client : 8 Mbytes/sec

What is the block size being used with dd? With smaller block
sizes, write throughput on native client would be low. If a bigger
block size like 128 KB is used, the throughput would be better.

The block size is 1k :<br>

dd if=/dev/zero of=/data/cms/500m-client-gluster-2 bs=1k
count=500000<br>

I'd like to use the gluster protocol because it can give me HA.
Can you
<br>
help me to increase the perfs ?
<br>
<br>
Thanks.
