[Gluster-users] Transport endpoint is not connected

[David Cunningham]

Hi Ravi and Joe,

The command "gluster volume status gvol0" shows all 3 nodes as being
online, even on gfs3 as below. I've attached the glfsheal-gvol0.log, in
which I can't see anything like a connection error. Would you have any
further suggestions? Thank you.

[root at gfs3 glusterfs]# gluster volume status gvol0
Status of volume: gvol0
