Note. remove the / when indicate the volume name, try like that and check if the volume is mounted before accesing it:<br>
<br>
mount (you should see 10gnode1:disp_vol on /mnt/gluster (rw,telatime..... etc)<br>

Hi, I have tested Disperse volume.<br>
<br>
so I perform a test using "dd"<br>
<br>
<br>
I'm using 4 nodes. and nodes are connected through 10g network.<br>

*Volume creation & mount command:*<span class=""><br>

10gnode4:/node/dispv<br>
This configuration is not optimal on most workloads. Do you want to use it<br>
? (y/n) y<br>
volume create: disp_vol: success: please start the volume to access data<br>
