Files > 2Gb

[Johan Barelds]

Hi all,

I am using HP-UX 11.00.
Can someone tell me if it can handle files > 2Gb ?

Thanks!

yes.

You must set largefiles option.

At creation :
mkfs -F vxfs -o largefiles /dev/vgXX/mylv
mount -F vxfs -o largefiles /dev/vgXX/mylv /mnt/point

for an existing LV without largefiles :
fsadm -o largefiles /mnt/point

It can but you have to flag the filesystem to handle it.

fsadm -F vxfs -o large files /dev/vgXX/lvolXX

I think you can do this on the fly even without Online JFS.

Yes. You need to enable "largefiles" on the filesystem itself. Assuming you are using vxfs filesystems, fsadm -F vxfs -o largefiles /myfilesys. The command for hfs filesystems are quite similar. Man fsadm_vxfs and mount_vxfs for details.


Note: Just because the OS/filesystem can handle files larger than 2GB does not mean that an application can. You also need to check with your software developer.

Clear.
Thanks guys!

Mixing Dave's answer and mine :)

My mistake : fsadm needs lv, not fs.
His mistake : no space in largefiles.

So the right command is :
fsadm -F vxfs -o largefiles /dev/vgXX/lvolXX

fsadm -o
