[Sysadmins] ext3 corruption on 2.6.18-ovz-smp-alt23.M40.2

[Vladimir V. Kamarzin]

Hi

# uname -r
2.6.18-ovz-smp-alt23.M40.2

Сервер на 4.0 бранч, md-raid1, консистентный.

Поймал повреждение fs после 35-и дней аптайма, некорректных выключений и
перезагрузое не было.

Ничего конкретного не гуглится кроме упоминания о подобных проблемах. Ещё
