Hi,
At CIEMAT-LCG2, we have a glite-cluster node and feel reasonably happy
with it. I think it makes more sense to have just one node publishing
the farm information (physical/logical slots in Glue1 but also VOViews
in Glue2). Otherwise, you need manual tweaking or have duplicated
information (and possibly inconsistencies...). I guess that's why it was
invented :-)
We did find a number of YAIM-related bugs when configuring the cluster
node, but I think they were mostly (or all) fixed. We didn't have a look
at EMI-3 yet though. Regarding number of sites using is, I have no data,
but I'd bet it's not too high...
Cheers,
Antonio
