Hi,

Hoping someone can help me identify why I keep having to restore my
database.  You can see below, that my machine shut down normally, yet when
I restarted the machine back up, I'm getting the error
'mysql\innodb_table_stats.ibd. Cannot open tablespace' and am having to
delete the current database and restore my backup.

Here is my Error log file.

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.
