Hi, are you sure there are not two hosts with the same IP address?
Happened to me once and logs looked pretty similar (frequent
disconnects, all other clients seemed fine, gluster cluster reported
no issues).

status` looks normal, as does a `gluster v status`. Server.allow-insecure is set
to on.

exactly sure what that's telling me, or what I can do about it. Two other
hosts currently have the volume mounted and can write just fine; Because of
operational reasons, I have not tested to see what would happen if I un/remount
it on the currently functioning hosts. I trialed it disabling iptables, no
change.
