Thanks for your response.
I tried to your suggestion.
root@node1:~/gluster_ec# mount
...
10gnode1:disp on /mnt/gluster type fuse.glusterfs (rw,default_permissions,allow_other,max_read=131072)
root@node1:~/gluster_ec# !dd
dd if=/dev/zero of=/mnt/gluster/test.io.1 bs=1024k count=1024 oflag=direct
dd: error writing ‘/mnt/gluster/test.io.1’: Invalid argument
dd: closing output file ‘/mnt/gluster/test.io.1’: Invalid argument
but, I got the same error.
Regards.

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

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

This configuration is not optimal on most workloads. Do you want to use it

To recognize why, I saw logs. but I didn't know reasons.
