Below is the procedure to convert a HFS file system from nolargefiles to largefiles.

Difference between nolargefiles and largefiles:

A file system which has been created with nolargefiles option is not capable of storing any files which are large than 2 GB.

To do so, we need to mention the largefiles option while creating the file system as below:

#newfs -F hfs -o largefiles /dev/vg02/rlvol1

The default is nolargefiles. If no option is mentioned, the maximum file size in the file system will be limited to 2 GB.

If the file system is already created with nolargefiles option, it can be changed to largefiles as below:

1.      Unmount the file system.

2.      Convert the file system to largefiles using the below command:

fsadm -F hfs -o largefiles /dev/vg03/rlvol1

3.      mount the file system back.
