MySQL 出现 The table is full 的解决方法 : https://my.oschina.net/longjianghu/blog/162960
今天在执行一个数据插入操作时，程序抛出 Cause: java.sql.SQLException: The table 'tb_logs' is full异常，看了一下相关文章，说是MySQL临时空间和堆空间的时间，就尝试可不可以删除一些数据，truncate table tb_logs，抛出table doesn‘t exist，执行任何命令没有反应，于是就根据相关文章中的提示修改配置
tmp_table_size = 32M max_heap_table_size = 32M
重启mysql没有反应，查看mysql错误日志，
Donad_Draper:/home2/mysql # view -f mysqld.log 2017-05-05 18:11:21 28045 [Note] Server socket created on IP: '::'. 2017-05-05 18:11:21 28045 [ERROR] /usr/sbin/mysqld: Error writing file '/mysqldata/Donad_Draper.pid' (Errcode: 28 - No space left on device) 2017-05-05 18:11:21 28045 [ERROR] Can't start server: can't create PID file: No space left on device 170505 18:13:38 mysqld_safe Starting mysqld daemon with databases from /mysqldata 2017-05-05 18:13:38 f74316d0 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.
从日志来看是磁盘空间不够的原因，查看磁盘空间，
Donad_Draper:/mysqldata # df -lh Filesystem Size Used Avail Use% Mounted on /dev/disksafe/sda3 32G 17G 14G 56% / udev 3.9G 132K 3.9G 1% /dev tmpfs 12G 76K 12G 1% /dev/shm /dev/disksafe/sda1 189M 127M 53M 71% /boot /dev/mapper/vg_mysqldata-lv_mysqldata 30G 30G 0 100% /mysqldata
果然是磁盘空间满的原因，由于系统部的人不在，敝人不会扩磁盘空间，又想赶快把问题解决，不想留在下周，所以用了的个最笨的方法，移除一些不要的数据库物理文件，
查看mysql数据目录：
Donad_Draper:/mysqldata # ls auto.cnf area_data3 ibdata1 area_data1 mysql-bin.index area_data5 dls_databack ib_logfile0 Donad_Draper.pid mysql performance_schema area_data4 area_data2 ib_logfile1 lost+found mysql-bin.000001 center_data Donad_Draper:/mysqldata #du -sh * 4.0K auto.cnf 22G dls_databack 16M area_data2 1.1G area_data3 49M ib_logfile0 49M ib_logfile1 13M ibdata1 4.0K Donad_Draper.pid 4.0K lost+found 16M area_data1 2.2M mysql 4.0K mysql-bin.000001 4.0K mysql-bin.index 636K performance_schema 5.0M area_data4 16M area_data5 6.3G center_data
由于center_data库，已是陈旧的数据库，所以就把这个物理文件移动别的磁盘
Donad_Draper:/mysqldata # mv center_data /home2/bak/ Donad_Draper:/mysqldata # Donad_Draper:/mysqldata # df -lh Filesystem Size Used Avail Use% Mounted on /dev/disksafe/sda3 32G 19G 12G 62% / udev 3.9G 132K 3.9G 1% /dev tmpfs 12G 76K 12G 1% /dev/shm /dev/disksafe/sda1 189M 127M 53M 71% /boot /dev/mapper/vg_mysqldata-lv_mysqldata 30G 24G 4.8G 84% /mysqldata Donad_Draper:/mysqldata #
在重新启动数据库，可以了使用。
所以在下次出现这个The table 'tb_logs' is full这个问题时，首先检查是不是磁盘空间满的问题，查看服务器状态：
mysql> show status; +-----------------------------------------------+-------------+ | Variable_name | Value | +-----------------------------------------------+-------------+ | Aborted_clients | 0 | | Aborted_connects | 0 | | Binlog_cache_disk_use | 0 | | Binlog_cache_use | 0 | | Binlog_stmt_cache_disk_use | 0 | | Binlog_stmt_cache_use | 0 | ... Ssl_cipher | | | Ssl_cipher_list | | | Ssl_client_connects | 0 | | Ssl_connect_renegotiates | 0 | | Ssl_ctx_verify_depth | 0 | | Ssl_ctx_verify_mode | 0 | | Ssl_default_timeout | 0 | | Ssl_finished_accepts | 0 | | Ssl_finished_connects | 0 | | Ssl_server_not_after | | | Ssl_server_not_before | | | Ssl_session_cache_hits | 0 | | Ssl_session_cache_misses | 0 | | Ssl_session_cache_mode | NONE | | Ssl_session_cache_overflows | 0 | | Ssl_session_cache_size | 0 | | Ssl_session_cache_timeouts | 0 | | Ssl_sessions_reused | 0 | | Ssl_used_session_cache_entries | 0 | | Ssl_verify_depth | 0 | | Ssl_verify_mode | 0 | | Ssl_version | | | Table_locks_immediate | 98 | | Table_locks_waited | 0 | | Table_open_cache_hits | 1 | | Table_open_cache_misses | 41 | | Table_open_cache_overflows | 40 | | Tc_log_max_pages_used | 0 | | Tc_log_page_size | 0 | | Tc_log_page_waits | 0 | | Threads_cached | 0 | | Threads_connected | 7 | | Threads_created | 7 | | Threads_running | 2 | | Uptime | 510 | | Uptime_since_flush_status | 510 | +-----------------------------------------------+-------------+ 341 rows in set
服务器状态没有什么问题，在查看表状态：
mysql> show table status where name='tb_logs'; +-----------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+------------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +-----------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+------------+ | tb_logs | InnoDB | 10 | Compact | 3 | 5461 | 16384 | 0 | 16384 | 0 | 32328 | 2017-05-05 19:02:13 | NULL | NULL | utf8_general_ci | NULL | | 操作日志表 | +-----------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+------------+ 1 row in set mysql>
如果是rows过多的原因，则修改表MAX_ROWS:
ALTER TABLE tb_logs MAX_ROWS=1000000000;
这个不建议做。
否则查看mysql临时空间和堆空间大小
mysql> SHOW VARIABLES WHERE Variable_name LIKE '%table_size%'; +---------------------+----------+ | Variable_name | Value | +---------------------+----------+ | max_heap_table_size | 16777216 | | tmp_table_size | 16777216 | +---------------------+----------+ 2 rows in set
如果是空间问题，修改相关配置：
Donad_Draper:/home/fsjrfw # vim /etc/my.cnf # The MySQL server [mysqld] tmp_table_size = 32M max_heap_table_size = 32M :wq
重启：
mysql> SHOW VARIABLES WHERE Variable_name LIKE '%table_size%'; +---------------------+----------+ | Variable_name | Value | +---------------------+----------+ | max_heap_table_size | 33554432 | | tmp_table_size | 33554432 | +---------------------+----------+ 2 rows in set mysql>
