15:07:45 — перезапуск физического сервера

Насколько я смог понять: ovs-vswitchd перезапустил соединение, NFS шара стала недоступна и кто-то стал этим фактом весьма недоволен.

Куда дальше копать пока непонятно.

XenServer зависает при экспорте виртуальной машины

Очень похожая проблема описывается в одной теме на форуме Citrix.

Существует ли сейчас на рынке дешевый (в плане заправки и цены отпечатка) надёжный ч/б лазерный принтер для SOHO?

У него есть проблемы, когда печатаешь через виндовую шару.

SATA/SAS-контроллер под Open Indiana/Solaris?

Спасибо, оригинал-то я и не догадался поискать.

Правда на забугорных форумах пишут, что на ebay M1015 можно ниже чем за 100$ взять. А у нас 300$ за LSI.

Запуск Mac Mini без монитора (загрузка Ubuntu Server)?

Что-то я не очень внимательно прочитал вопрос, возможно это вовсе не ваш случай.

Запуск Mac Mini без монитора (загрузка Ubuntu Server)?

У меня была похожая проблема с Ubuntu Minimal, но не на Mac Mini. Она почему-то пыталась грузиться в графический режим

Для начала попробуйте Ctrl+Alt+F1, чтобы попасть в консоль.

Я починил так:

sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT=\"quiet splash\"/GRUB_CMDLINE_LINUX_DEFAULT=\"\"/g' /etc/default/grub
echo "GRUB_GFXPAYLOAD_LINUX=text">>/ect/default/grub

sudo update-grub
