[Gluster-users] Fwd: Ignore failed connection messages during copying files with tiering

[Hari Gowtham]

Hi Paul,

We need the log messages to help you further with this. Can you get us
all the gluster logs and the output of gluster volume status and
gluster volume info.
and when the copy process seems to be suspended, i need the volume
status at that time.
The i would like to know what type of work load the machine is put through.
