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.
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.
key_buffer_size = 16777216
read_buffer_size = 131072
max_used_connections = 0
max_threads = 151
thread_count = 0
connection_count = 0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size) * max_threads = 346701 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

200507 13:38:39 Innodb: Database Was Not Shut Down Normally!

with Innodb_force_Recovery = 3 MySQL started. But do something either through the web does not work. Going “Got Error -1 error from Storage Engine”. And to different bases.

In this mode, it does not give anything to the database. What is better to do? Full removal of broken databases and return to normal mode?

Uponcing MySqlCheck –all-Databases All bases are indicated as ok.

And all the same, the problem is saved. MySQL table does not work normally. Does not touch it completely. Not loading from backup.

Answer 1

launched MySQL with Innodb_force_Recovery = 6 part of the data stacked in the table with which work was performed. After that, it removed the parameter and MySQL started correctly the data was removed and replaced from the backup.
