⒈、开启限制，生成用户和组限制文件
⒉［rootlocalhost ~］# quotacheck -avug
⒊quotacheck： Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown.
⒋quotacheck： Scanning /dev/sda ［/home］ done
⒌quotacheck： Cannot stat old user quota file /home/aquota.user： No such file or directory. Usage will not be substracted.
⒍quotacheck： Cannot stat old group quota file /home/aquota.group： No such file or directory. Usage will not be substracted.
