Dear all,
I'm working on si_netbootmond (in fact working on OSCAR side) and discovered
that
si_netbootmond rely on the fact that the imaging method is rsync.
It monitors the rsyncd log file for magic works stating that imaging is
complete.
There are 2 problems here:
1/ It doesn't work for deployment using flamethrower / multicast or bittorrent
2/ If a client is successfully imaged, this doesn't mean that it is able to
reboot (bad
image, bad bootloader, ...) in this situation, setting local boot is wrong as
we certainly
want to boot from net again in order to re-image.
I see 3 solutions:
1/ replace the actual code that scans /var/log/systemimager/rsyncd for magic
words:
/scripts\/imaging_complete_?([\.0-9]+)?/ with something that would do something
like:
use File::Monitor;
my $monitor = File::Monitor->new();
$monitor->watch('/var/lib/systemimager/clients.xml');
In a loop, searching for clients with status 102 (REBOOTED)
and run:
si_mkclientnetboot --localboot --clients "<the client>"
2/ Keep actual code and add an option to monitor client.xml instead
3/ drop or left si_netbootmond untouched and add an option to unable updating
the
netboot to local in si_monitor. Indeed, si_monitor won't require an active
checking of a
file. it is in blocking state on a socket listenning for infos. if it receives
message
rebooted, then it could call a:
si_mkclientnetboot --localboot --clients "<the client>"
Technically, solution 3 has the advantage of being passive while methode 1 and
2 are
active listenning of node status change. Problem of solution 3 is that I don't
know if
it's logic to have the hability to update netboot of client in si_monitor, and
I if
si_monitor is not started, then no possibility to update netboot.
What is the best solution?
Regards,
Olivier.
