I were probably doing something stupid...
Its working now, but... it loops through the list of servers and the
executes the task for each server 16 times in total.
role :dev_xml_gerrard, "longtct03g", "longtct03h", "longtct03i",
"longtct03j"
task :foo, roles => :dev_xml_gerrard do
find_servers(:roles => :dev_xml_gerrard).each do |server|
run "uname -a"
run "sleep 4"
end
end
I have taken multistage out of the equation and am only using this
code above.
