Одной из возможных причин может быть отключенный сервис сбора статистики lvestats.

Чтобы проверить статус сервиса:

  1. Подключитесь к серверу с ISPmanager по SSH.
  2. Проверьте статус сервиса:

    systemctl status lvestats
    CODE
  3. Если в ответе есть строка "Active: inactive (dead)", запустите сервис:

    systemctl enable lvestats
    CODE
    systemctl start lvestats
    CODE
  4. Через пять минут проверьте работу статистики:

    /usr/sbin/lveinfo
    CODE
