InnoDB: We do not continue the crash recovery, because the table may become

InnoDB: To fix the problem and start mysqld: 
InnoDB: 1) If there is a permission problem in the file and mysqld cannot 
InnoDB: open the file, you should modify the permissions. 
InnoDB: 2) If the table is not needed, or you can restore it from a backup, 
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal 
InnoDB: crash recovery and ignore that table. 
InnoDB: 3) If the file system or the disk is broken, and you cannot remove 
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf 
InnoDB: and force InnoDB to continue crash recovery here.

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=8388608 
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 = 68245 K bytes of memory 
Hope that's ok; if not, decrease some variables in the equation.

比如說備份了整個庫，這時就可以把資料庫初始化，然後把庫匯入
