И это всё МОЁ
Добрый день.
Задавал вопрос на forum.sql.ru, но там увы, не ответили.
Есть настроенный сервер IP телефонии на Astreisk и померший сектор на жестком диске. Не повезло файлу /var/lib/mysql/ibdata1 База не запускается, есть резервные копии, и хотелось бы восстановить ее из бэкапа..
Что за файл конкретно помер не знаю, но может можно восстановить базу из бэкапов без этой информации...
У самого опыта немного ни в linux, ни в mysql.
Сейчас задача - просто восстановить, чтоб запускалась вебморда и писались разговоры. Важны только данные конфигурации астериска\freepbx, чтобы не перенастраивать заново. Сама телефония сейчас работает и без mysql

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.1.24-MariaDB
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467125 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
