How to know whether my filesystem is largefiles or not?

How to know whether my filesystem is largefiles or not? I don't know if it can support the files large than 2GB.

Try:

# fstyp -v /dev/myvg/mylvol

If field 'f_flag' reports to be 16 then it is largefiles option. If not then it is not.
You can change it on the fly with 'fsadm' if you have an online JFS license, if not the filesystem needsto be unmounted.

Kevin,

Have a look at the entries in your fstab file:

# more /etc/fstab
/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /home vxfs delaylog 0 2
/dev/vg00/lvol5 /opt vxfs delaylog 0 2
/dev/vg00/lvol6 /tmp vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2
/dev/vg10/lvol1 /u01 vxfs rw,suid,largefiles,delaylog,datainlog 0 2
/dev/vg00/lvol9 /u02 vxfs rw,suid,largefiles,delaylog,datainlog 0 2
/dev/vg00/lvol10 ... swap pri=0 0 0

If the LVOL contains 'largefiles', files larger than 2GB are supported.

best regards,
Kurt

You can confirm using SAM as well:

SAM --> Disk & File Systems --> File Systems.

Change the View --> Columns --> Select options.

This will show files system that have largefiles in the column "Options".

The command
fsadm -F vxfs
will respond with options set, such largefiles or nolargefiles.

Try this:
fsadm -F hfs /dev/vg00/rlvol?
or
fsadm -F vxfs /dev/vg00/rlvol?

? = lvol number (or name)
