Hayden 14 Comments While running into MySQL's open files limit will manifest itself into various error messages, this is the standard one that you'll receive during a mysqldump: XHTML mysqldump: Got error: 29: File './databasename/tablename.MYD' not found (Errcode: 24) when using LOCK TABLES 12 mysqldump: Got error: 29: File './databasename/tablename.MYD' http://blog.infusiontechsolutions.com/mysqldump-error-29/ not found (Errcode: 24) when using LOCK TABLES The best way to get to the bottom of the error is to find out what it means: XHTML $ perror 24 OS error code 24: Too many open files 12 $ perror 24OS error code24:Too https://major.io/2007/08/19/mysql-errcode-24-when-using-lock-tables/ many open files There's two ways to fix the problem. First, if you find that you only hit the limit during mysqldumps and never during normal database operation, just add --single-transaction to your mysqldump command line options. This will cause mysql to keep only one table open at a time. However, if this happens while backups aren't running, you may want to increase the open_files_limit in your MySQL configuration file. By default, the variable is set to 1,024 open files. For further reading: 5.2.3.

It seems to be just the first file it tries to access. Sometimes it's a *.MYD and sometimes it's a *.frm. I have some more databases that are quite the same and are still working. The file and out of resources directory permissions are the same for all databases. The database is still working. mysqlcheck -e says everytings OK myisamcheck didn't find an error A restart of MySQL didn't change anything I use MySQL 5.0.27 on OpenSuse 10.1 I hope someone can help me.

mysqldump utility is a MySQL database backup program that enables you to copy (or dump) a database to another SQL Server. This server may not necessarily be another MySQL Server. On most occasions, the MySQL dump contains SQL statements that are used to create tables and insert records in them. You can generate the data in the mysqldump utility in CSV or XML format as well. However, sometimes you are unable to use this utility to dump the database. Such problems can occur due to corruption in the database. The database corruption can occur due to various reasons such as virus infections, power outages, bugs in MySQL version, hardware issues, etc. In such cases, you should find out the cause of the problem and try to resolve the issue. If you are unable to fix the error, then you should use a third-party MySQL repair software to perform MySQL recovery. Consider a scenario wherein you are working on a MySQL database in which you want to dump a MySQL database to another location. However, you are unable to dump the database and an error message is displayed, that is: [root@www diaendomet]# mysqldump -ucojjohealth -p -all-databases > alldatabases.sql Enter password: mysqldump: Got error: 29: File ‘../diaendomet/users.MYD' not found (Errcode: 2) when using LOCK TABLES Cause: The primary cause of this erroneous situation is that the MySQL database is corrupted. It has corrupted due to any of the various reasons discussed in the introductory paragraph. Resolution: To resolve the situation, you should perform the following steps:Stop the MySQL server. Change the working directory to $ MYSQL_DATA_DIR Run the myisamchck utility as displayed: run myisamchck with */*.MYD. This command will complete a check on all the table files and repair wherever it finds any error. Restart the MySQL server and try to repeat the database dump. It should run fine now. However, there may be instances when this resolution does not provide the solution to the problem. This would invariably mean that the database is
