Re: largefile support

If you have online JFS

then to enable

# fsadm -F vxfs -o largefiles /

and for HFS it is

/usr/sbin/mkfs -F hfs -o largefiles /dev/vg02/rlvol1

look at http://docs.hp.com/hpux/onlinedocs/os/lgfiles4.pdf

Re: largefile support

You can check the file system support with

# fstype -v /dev/vgXX/lvolX

For more information see "Support for Large Files"
http://www.docs.hp.com/hpux/onlinedocs/B3929-90011/00/00/25-con.html

if the fs was created with the largefiles support, there is no problem with its existance, check with:

mkfs -m -F vxfs /dev/vgXX/lvol

Re: largefile support

Shalom,

largefiles is either set in newfs command -o largefiles or changed with fsadm

Re: largefile support

Hi Wagar:

# fsadm -v /dev/vgNN/rlvolX

...will return 'largefiles' or 'nolargefiles'

Regards!

You check using fsadm
Example:-
# fsadm -v /dev/vg00/rlvibmitm
nolargefiles --> meaning no largefile support enabled.

Problems are common to all, but attitude makes the difference
