Hi all, I am having issue to copy/move files to my replicated volume residing inside the aws volume. I will explain my current setup. I have created two instances in aws and attached a 50GB volume to each of them. I have mounted those volumes at the mount points /gluster_brick1 and /gluster_brick2 respectively. I have created another directory /gluster_brick1/data/ and /gluster_brick2/data/ as two bricks for the glusterfs replications. I have followed the below link for replication setup that was working nicely for me.
https://gopukrish.wordpress.com/glusterfs/ My volume name is datavol and is mounted to each of the servers in the location /home/mytestlo/public_html. gluster replication is working fine as expected when i create files. But when I copy or move files to the datavolume, i get error : Remote I/O error.
