You may run quotacheck at any time if you don't mind slightly incorrect qotas as changes done on already checked files while qotacheck is running wouldn't be noticed. You may skip quotacheck at startup at all - if your server didn't crash quotas should stay in sync. So you could use some off-peak time for quotacheck at runtime and do this once in a while. -- Konstantin Münning
