Re: [Testbed-admins] database info reset by nfree command

[Hussamuddin Nasir <nasir@netlab.uky.edu>]

More specifically i see the problem in the nfree script

######################################################################
# Step 1b
#
# Ugh.  If we are resetting the PXE boot program for any of the nodes
# we need to clear them and regenerate the dhcpd.conf file now, before
# we start freeing up nodes in Step 2.  If we delayed HUP'ing til after
# Step 2, then nodes might have already been rebooted by the reload
# daemon.
#
# NOTE: this does not happen very often. elabinelab, plabinelab?
#
foreach my $node (@freed_nodes) {
    if ($node->pxe_boot_path() && $node->pxe_boot_path() ne "") {
        $node->Update({"pxe_boot_path" => "NULL"}) == 0 or
            die("*** $0:\n".
                "    Could not update pxe_boot_path for $node\n");
        $mustmakeconf = 1;
    }
}
if ($mustmakeconf) {
    system("$makeconf -i -r") == 0 ||
        print STDERR "*** WARNING: $makeconf failed!\n";
}

Do we need this or can i comment this out ??

cheers,
