Change the file size limit

Dear Lucas,

By default, the maximum file size is 2 GB after AIX is installed. Files larger than 2 GB cannot be created under any directory. However, files larger than 2 GB are common. To ensure normal file creation, you need to change the file size limit in the /etc/security/limits file.

To change the file size limit, perform the following steps:

1. Run the vi /etc/security/limits command to edit the file.

2. Change fsize in the file to -1, where -1 indicates no limits on file size.

The change takes effect immediately without the need to restart the system.

3. Run the following command to verify that the change takes effect:

bash-3.00# ulimit -a

In the output, file size is changed to unlimited, indicating that the change has taken effect.

Thanks.
