For what it's worth, Puppet appears to use straight O_EXCL locking<https://github.com/puppetlabs/puppet/blob/fd78c22fe07500dedc254f02389cb0954d7e5540/lib/puppet/util/lockfile.rb>, which, indeed, does not work reliably on NFS file systems. It might be amusing to file an RFE ticket for this, but that won't get you a solution in time to serve your present need. I'd be surprised if PuppetDB would serve this purpose. It's an interesting problem. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
