This script serves that function. To do this, we begin by collecting disk usage from all worker nodes. For each user, we compute disk usage on all worker nodes then alter quotas so that each individual nodeās account for the user has a quota proportional to disk usage. For example: consider a user with a 10-MiB quota who uses a Mail worker. Assume that the local (controller) node uses 3.1 MiB of space, and the Mail node uses 6.2 MiB. In this setup, the controller account uses 1/3rd of the accountās total disk usage, so weāll assign it that share of the quota, or 3.33 MiB. Likewise, the Mail worker uses 2/3rds of the accountās total disk usage, so weāll give it 6.67 MiB of the quota. Note that we donāt actually limit users until they reach a threshold of disk usage; until that time each of the userās nodes has the full quota (for example, 10 MiB for this user). =cut #---------------------------------------------------------------------- use parent qw( Cpanel::HelpfulScript ); use List::Util; use AnyEvent (); use Cpanel::Config::Users (); use Cpanel::LinkedNode::QuotaBalancer::Run (); use Cpanel::Output::Formatted::Terminal (); use Whostmgr::ACLS (); use constant _OPTIONS => ('verbose'); our ( $a, $b ); __PACKAGE__->new(@ARGV)->run() if !caller; #---------------------------------------------------------------------- sub run ($self) { local $ENV{'REMOTE_USER'} = getpwuid $>; Whostmgr::ACLS::init_acls(); my $cv = AnyEvent->condvar(); my @usernames = Cpanel::Config::Users::getcpusers(); my $logger = Cpanel::Output::Formatted::Terminal->new(); my $runstate = Cpanel::LinkedNode::QuotaBalancer::Run::run_for_users( \@usernames, $logger, verbosity => $self->getopt('verbose') ? 1 : 0, ); $runstate->get_promise()->finally($cv); $cv->recv(); return; } 1;
