MS-APP02   - Node 2 Cluster peacemaker + COROSYNC

На сервере HVX03 после ошибки segfault отключился, удалился и пересоздался виртуальный сетевой интерфейс виртуальной машины MS-APP01. Все ресурсы кластера были запущенны на сервре MSK-HVX04 в виртуальной машине MS-APP02. На виртуальной машине по прошествии 8 дней возникла такая же ошибка. После ошибки segfault отключился, удалился и пересоздался виртуальный сетевой интерфейс виртуальной машины MS-APP02

Вопрос почему появляется ошибка и почему отключаются паравирт. сетевухи только этих машин

Рухнула виртуалка, система удалила виртуальный сетевой интерфейс из моста. При перезапуске виртуалки создался новый интерфейс, который был добавлен в мост.

Может память побилась, может ещё чего.

Я бы понял, если бы это было на одном сервере) Но это повторилось на втором серваке. Так что точно не память (

Если версии всего софта и состав виртуалок одинаковый, то скорее всего какой-то глюк qemu.

На втором сервере в выхлопе тоже есть ошибка сегментирования?

Напоминает Guru Meditation у VirtualBox.

Перегрузил виртуалку вручную, всё завелось.

Для виртуалки такое падение примерно как Reset для компа.

Нет возможности развернуть проблемную виртуалку на более свежем ПО? ИМХО стоит начать с этого.

Насколько я понимаю, в виртуалках крутится оффтопик. Как мне кажется, надо копать в направлении их содержимого, и что изменилось, раз они работали и внезапно начали падать. Сталкивался с одной неприятной программулей использующей java, ее запуск под оффтопиком примерно также наглухо валил qemu-kvm

Там крутится SAP (это машинка кластер центральных инстанций) всё остальное это диалоговые инстанции

Память с Ecc она проверенна и ошибок нет. Прикол в том что недавно на другой ноде сервера произошло тоже самое..( Соседний сервер. Там диалоговая инстанция sap (точнее на ней 4 виртуалки). В итоге та же самая ошибка на хосте гипервизора и отключение интерфейса виртуальной машины (одной). Другие диалоговые инстанции продолжали работать и не висли. Принудительно перегрузили зависшую всё поднялось и работает. При этом в самой зависшей виртуалке ничего нет.. ни единой ошибки.

В виртуалке
