Уже несколько часов безуспешно пытаюсь восстановить данные. :( |

C livecd видно, что RAID работает исправно: |

livecd ~ # cat /proc/mdstat |

Память на всякий случай протестировал - memtest86 в течении двух |
| 38 |
часов ошибок не нашел. Пытаюсь разобраться как можно восстановить LVM, |
| 39 |
но не хватает теоретических знаний. |
