ERROR 1114 (HY000): The table 'xxxx' is full

Answer 1

Even if you have file-per-table active, deleting rows causes the old versions of rows to be copied to the central tablespace ibdata1 . Just in case you roll back the delete, or in case there are other transactions reading the database who need to see the rows you deleted to preserve their repeatable-read view of the database.

The reason it clears up after a few seconds is that InnoDB gradually purges these copies of obsolete rows, and makes space in ibdata1.

Normally ibdata1 can auto-extend if it needs to store more data in its rollback segment. Did you configure ibdata1 without the autoextend keyword?

mysql> SHOW GLOBAL VARIABLES LIKE 'innodb_data_file_path';
+-----------------------+------------------------+
| Variable_name         | Value                  |
+-----------------------+------------------------+
| innodb_data_file_path | ibdata1:10M:autoextend |
+-----------------------+------------------------+

Without the autoextend keyword, the ibdata1 file has a fixed size, and you can fill it up pretty easily when you delete a lot of rows.
