reclaim disk space
Dear Friends how to reclain the disk space used by an table that was dropped? Regards Luiz -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: reclaim disk space
Luiz, if you are working with MyISAM tables, the table files should be deleted when you DROP the table. If not, you might have an OS permissions issue. If you are working with InnoDB tables in one tablespace, you cannot currently easily reclaim the space. See http://bugs.mysql.com/bug.php?id=1287 One way to work around the InnoDB behavior is to enable the file-per-table option when you do initial set up; it's discussed in the link above.

For most storage engines, each table is in its own file so a dropped table immediately returns space back to the OS. For InnoDB in tablespace mode (i.e. innodb_file_per_table is unset), you will have to back up and drop all your InnoDB tables, delete the tablespace files, and reload the tables. http://dev.mysql.com/doc/refman/5.0/en/adding-and-removing.html http://dev.mysql.com/doc/refman/5.0/en/multiple-tablespaces.html -- Dan Nelson [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: reclaim disk space
I had to do some disk space recovery mysql last month... I have backed up some of the raw .MYI, .MYD files and deleted them from the data directory. Running 5.0.18, I had to shut down mysql and restart before it freed up the space. -Original Message- From: Dan Nelson [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 21, 2006 3:58 PM To: luiz Rafael Cc: mysql@lists.mysql.com Subject: Re: reclaim disk space In the last episode (Jun 21), luiz Rafael said: how to reclain the disk space used by an table that was dropped?
