Как я понял решение у проблемы следующее:
1. Найти номер блока файловой системы по LBA - convert bb <LBA> agbno
2. Прыгнуть в нужный блок - fsb <BNO>
3. Запросить информацию: blockget

Но, на третьем шаге возникает ошибка:
"ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_db.  If you are unable to mount the filesystem, then use
the xfs_repair -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this."

Что это такое и как с этим бороться?
