Disable file size limit in AIX
Posted by Lincoln Zuljewic Silva in Aix on December 4th, 2009
By default, if you try do copy/create a file larger than 2Gb in AIX, you will get a “file too large” message. That happen because AIX have a default limit of 2Gb for files.
To disable (or increase) this limit, edit /etc/security/limits and change the parameter fsize to “-1” or whatever value you want.
You can change it in “default” to apply to all users or change it to a specific user.
Remember that the file system should be JFS2.
