Hi,

# usr/sbin/fsadm -F vxfs -o largefiles /dev/vgxx/rlvolx

and don't forget to update the /etc/fstab

Re: Create a large filesystem after creating filesystem

you can use sam also and check the largefiles box for large files support.

Hi,

You can use fsadm as suggested by Robert or if you do not have any data on the filesystem as yet , you can recreate the filesystem , this time give the
-o largefiles
option with the mkfs/newfs command. and modify /etc/fstab entry to update the largefiles option.

Re: Create a large filesystem after creating filesystem

Hi Dhamodharan,

With Online-JFS

#/usr/sbin/fsadm -F vxfs /file_system_path
If the output shows largefiles, then large files are activated.If it shows nolargefiles large files are inactive.

To change a file system to support large files, do following:

# /usr/sbin/fsadm -F file_system -o largefiles /dev/vgxx/lvolx

for example
# /usr/sbin/fsadm -F vxfs -o largefiles /dev/vg01/lvol6
