[gpfsug-discuss] GPFS GUI

[David D. Johnson]

I have issues as well with the gui. The issue that I had most similar to yours
came about because I had installed the collector RPM and enabled collectors on
two server nodes, but the GUI was only getting data from one of them. Each client
randomly selected a collector to deliver data to. 
So how are multiple collectors supposed to work?  Active/Passive? Failover pairs?
Shared storage?  Better not be on GPFS…   Maybe there is a place in the gui config
to tell it to keep track of multiple collectors, but I gave up looking and turned of the
second collector service and removed it from the candidates.

Other issue I mentioned before is that it is totally confused about how many nodes are
in the cluster (thinks 21, with 3 unhealthy) when there are only 12 nodes in all, all healthy.
The nodes dashboard never finishes loading, and no means of digging deeper (text based
info) to find out why it is wedged.
