largefiles clarification

[manu_15]

Hi ,

In hfs/vxfs filesystem , whether the largefiles are allowed by default or we require onlinejfs for the largefiles option to get active.Can anybody please clarify.

Thanks

Online JFS is not required to convert a system to largefiles.

The fsadm utility, which gets additional functionality under OnlineJFS is used to convert the filesystem.

Thats why the confustion. If you look at a system without OnlineJFS, you will see that the fsadm tool exists and has the necessary functionality to convert a filesystem.

large file is not default for hfs/vxfs filesytem.
You can change to largefile system by command:
#umount /dev/vgxx/lvolx /mount_point
#fsadm -F vxfs/hfs -o largefiles /dev/vgxx/lvolx

add to this u can do fsadm -v to see the filesystem his currently using largefiles or not.
