Hi Kaushal,
So my gluster FUSE clients are using not vanilla centos AMI, the AMI is one of the versions by bashton:
https://www.bashton.com/blog/2015/centos-7-2-1511-ami/
My gluster cluster server AMI is using, our in-house AMI, that has some sysadmin packages, epel and docker baked-in.
I created a pretend client machine using our in-house AMI, I mounted the same cluster, the same way, with the same version of glusterfuse as on the broken client. Then I copied the same files again. The new pretend client had not a single issue. no issues in logs, everything completed successfully without problems.
I think - the problem is solved with the in-house AMI.
What can I share to help people investigate if it's the OS + package combination that might be breaking their gluster?
Regards,

The "gluster" volume is still writeable on the gluster servers.
gluster volume status does not report anything funky.If I kill the glusterfs process on the client (the box that has gluster volume mounted via fuse), and then MOUNT again, I can carry on copying and writing, until I get those errors again.I have successfully copied the same amount of data directly to the XFS volume on the glusterfs server nodes, I believe my XFS works.All the machines are on AWS, and none of the resources are exhausted IO/RAM/CPU/NETWORK, not on client, not on gluster cluster.Please help!Posting the `gluster vol info` output for the volume will help everyone get a better picture about your volume (sanitize it to remove any sensitive information first).Have you enabled any options on the volume, particularly any quorum options? Client-quorum makes a client read-only when it cannot connect to a quorum of servers (normally 50% of replica count +1 ).You mount log shows that you've had connections issue (a lot of 'Transport endpoint is not connected' messages).Can you verify that the network between the client and server isn't having problems when you see these errors?
