[Gluster-users] gluster 3.6.1 mount failed with no error to terminal (sometimes)

[Kingsley]

I have four CentOS 7 servers set up with gluster 3.6.1 and have a single
replicated volume across these. All servers are set up the same as each
other and are brand new installations.

To test, I've mounted the volume on each so that each server can also
use the volume as a client.

The weird thing is, while the mount failed for an obvious reason, I
didn't always get an error back to the terminal (I pasted the mount
command to the other terminal windows before spotting I'd made a typo in
the server name, which is why the mount attempts had failed). Why would
an error not be sent to the terminal sometimes, but not always?

Transcript:

[root at gluster1b-1 ~]# mount -t glusterfs glsuter1a-1:gv0 /mnt/gv0
Mount failed. Please check the log file for more details.
