Scott, >From the innodb manual. It looks like you can only autoextend the last datafile >listed. Starting from versions 3.23.50 and 4.0.2 InnoDB allows the last data file on the innodb_data_file_path line to be specified as auto-extending. The syntax for innodb_data_file_path is then the following: pathtodatafile:sizespecification;pathtodatafile:sizespec;... ...;pathtodatafile:sizespec[:autoextend[:max:sizespecification]] If you specify the last data file with the autoextend option, InnoDB will extend the last data file if it runs out of free space in the tablespace. The increment is 8 MB at a time. An example: innodb_data_home_dir = innodb_data_file_path = /ibdata/ibdata1:100M:autoextend instructs InnoDB to create just a single data file whose initial size is 100 MB and which is extended in 8 MB blocks when space runs out. If the disk becomes full you may want to add another data file to another disk, for example. Then you have to look the size of ibdata1, round the size downward to the closest multiple of 1024 * 1024 bytes (= 1 MB), and specify the rounded size of ibdata1 explicitly in innodb_data_file_path. After that you can add another data file: --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
