ruby - When a task fails on a server, run a different task on only that server -

-

i have capistrano task restarts background job on multiple servers. sometimes, job have died on server, , restart command fail because job isn't running. in case i'd call start task (rather restart task). here's attempt:

namespace :job   desc "restart job"   task :restart, :roles => :app     output = nil     begin       run "sudo restart myjob deploy=true name='myjob1'" |channel, stream, data|         output = data       end     rescue capistrano::commanderror => error       if output.match("restart: unknown instance: myjob")         puts "****** warning ***** job not running -- starting it"         start       else         puts "some other unknown error, die"         raise error       end     end   end    desc "start job"   task :start, :roles => :app     run "sudo start myjob deploy=true name='myjob1'"   end end

the problem i've done above, when call "start", run start task on servers, when want run on server died. maybe can pass host start command somehow? haven't been able find how tho. cheers.
