На моем домашнем сервере внезапно заболел раздел JFS. Этот раздел использовался для торрентов и SVN, скорее всего он полностью заполнен данными. И пару дней назад система перестала отвечать. После перезагрузки убунту сообщила, что раздел sdb6 поврежден и его необходимо восстанавливать вручную.
Я подключил диск к другой машине, попытался провести обычные операции:
# fsck.jfs /dev/sdb6
fsck.jfs version 1.1.12, 24-Aug-2007
processing started: 5/22/2010 21.36.23

ujfs_rw_diskblocks: read 0 of 4096 bytes at offset 536870912
Unrecoverable error reading M from /dev/sdb6. CANNOT CONTINUE.
Не помогло, разумеется. При монтировании сообщается об ошибке(при необходимости, я сообщу о ней, сейчас сканирую диск badblocks)
Все остальные диски монтируются нормально.
Смарт говорит, что отказ неминуем:

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.Я не знаю, какие данные сообщить вам, называйте команды, я дам выводы их. Так же я никогда не занимался восстановлением и анализом дисков в linux.
Передо мной задача: выяснить причину сбоя и восстановить диск.
Спасибо за помощь.
