[one-users] onehost sync

Fri Oct 25 09:22:12 PDT 2013

Hi Olivier,

I don't know what could be going on. When the core detects that the
remotes_dir has been "touched" by the "onehost sync", then it sends a
special argument to the driver which forces an 'scp' of the remotes...

As a workaround I can only tell you what you already know, which is to
manually scp the remotes over to the hosts... To debug it, we could gdb the
oned process and see what's going on, especifically here:
https://github.com/OpenNebula/one/blob/one-3.8/src/im/InformationManager.cc#L224

The upcoming OpenNebula 4.4 version won't have this problem, though. The
scp will be triggered by the actual 'onehost sync' command, instead of the
core. This is an advantage in many ways because it'll be easier to debug
and because you can select what hosts/clusters to update:
https://github.com/OpenNebula/one/blob/master/src/cli/one_helper/onehost_helper.rb#L161

cheers,
Jaime
