That's pretty much expected behaviour if you understand what exec() does. From http://www.ruby-doc.org/core/classes/Kernel.html#M005968 : Replaces the current process by running the given external command. I suspect that what you were really looking for was the system() function. Although doing mirroring in the Puppet *master* doesn't seem like a particularly good idea at all. Why do you want to do that? Isn't it better to do that in the client (possibly the client running on the same machine as the master, but still in the client)? > BTW: If there's an easier way to synchronize directories, I'm open to > using it.

If the source directory resides on the Puppet master, or on the same machine as the destination and where you are running puppetd, you can do it using the normal file type. If it resides on a different machine, the following definition might help you: # Mirror a directory tree using rsync. define rsync_mirror($source, $target, $sshkey="", $unless="", $onlyif="", $creates="", $month="1-12", $monthday="1-31", $weekday="0-7", $hour="", $minute="", $ensure="present" ) { if $sshkey { $sshcmd = "ssh -i$sshkey" } else { $sshcmd = "ssh" } $rsynccmd = "rsync -aRqv --no-implied-dirs --delete --delete-excluded" $command = "RSYNC_RSH=\"$sshcmd\" $rsynccmd '$source' '$target'" case $ensure { "present": { exec { "$rsynccmd '$source' '$target'": path => "/bin:/usr/bin", unless => $unless ? { "" => undef, default => $unless }, onlyif => $onlyif ? { "" => undef, default => $onlyif }, creates => $creates ? { "" => undef, default => $creates }; } if $hour { cron { "mirror--$title": command => "PATH=/bin:/usr/bin; $command", user => "root", month => $month, monthday => $monthday, weekday => $weekday, hour => $hour, minute => $minute; } } } "absent": { tidy { $target: recurse => true, rmdirs => true, size => 0, backup => false ; } cron { "mirror--$title": command => "PATH=/bin:/usr/bin; $command", ensure => absent; } } default: { fail("Bad rsync_mirror parameter ensure: $ensure") } } } This does an rsync directly, and optionally creates a cron job that continues doing the rsync regularly. That way you don't need to tie up your normal Puppet runs with the rsync, only the first time. Use it something like this: rsync_mirror { centos-5-x86_64: source => "rsync://my.centos.mirror/CentOS/5/os/x86_64/./", target => "/var/cache/mirrors/centos-5.x86_64/", creates => "/var/cache/mirrors/centos-5.x86_64/images/README", hour => 2, minute => 10; } The month, monthday, weekday, hour and minute parameters control the cron job. The creates, unless and onlyif parameters control if Puppet should run rsync immediately, exactly like the exec type. /Bellman --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
