You can do it from SAM, or manually, us
ing fsadm:

/usr/sbin/fsadm -o largefiles /dev/vgxx/lvolyy

see "man fsadm"

Use fsadm

fsadm -o largefiles /device_name

mount -p to confirm it.

Taking your request litarily, it would be something like:
dd if=/dev/zero of= bs=1024 count=

If you mean you want to allow large files on a filesystem, it depends on the filesystem type. HFS filesystems need it to be specified when mounting the filesystem, while vxfs needs it to be set using fsadm. Depending on whether you have onlineJFS the last can while the filesystem is mounted or not.

Hi,
if you just want to test if it possible to create a big file, e.g. >2GB in a filesystem, try this:
# prealloc mybigfile 2200000000

which creates a file of the speciified byte size.

regards,
John K.
