Subject: [Sysadmins] Линк через usb работает один раз?
Date: Thu, 28 Feb 2008 14:21:00 +0300
Message-ID: <47C6991C.5090809@codis.com.ru> (raw)
Здравствуйте!
Строю кластер на ALS4 -drdb,had,ovz.
Серверы соединены кросс-кабелем ethernet (и через LAN)
Хочу сделать дополнительный линк для had .
Серверы 1U доп. сетевую не поставить.
Воткнул кабель usb-pc link
Получил

На обоих серверах идентичная картина
Пошёл читать доку по etcnet ,iftab прочее нужное чтобы задать IP
на этом интерфейсе да и переименовать.
Что-то нарисовал-не работает- вошел в цикл изучения.Нормально.
На свежую голову с утра перезапустил сервер
После этого usb устройство потерялось. Навсегда(?)
При загрузке и попытках переткнуть кабель приводит к сообщениям вида

-----------------------
Перевтыкание кабеля на втором сервере (без перезагрузки) привело к
аналогичным результатам.
Кто знает что это такое где чинить?
