Largefile system
I created a filesystem supporting the largefile option. Please, can someone shed some light as to how to mount it with that option. I am on hp-ux 10.20
Thanks in advance,
Iqbal

Re: Largefile system
To manually mount the filesystem with largefiles option use,
mount -F vxfs -o largefiles /dev/vg_name/lv_name /mount_point
use "hfs" in place of "vxfs" if you are using a hfs filessytem.
To set the option automaticlly in /etc/fstab have the option largefiles added to other options for the filesystem.
Hope this helps.

Re: Largefile system
If you have enabled the 'largefiles' support, then you can create largefiles without doing anything special. The 'largefiles' / 'nolargefiles' mount options as defined in '/etc/fstab' can be used to signify and control largefile support as noted in table-1 in this document:

Re: Largefile system
you can follow this way for vxfs file system
mount -F vxfs -o largefiles /dev/vg_name/lv_name /mount_point
and for hfs replace hfs with vxfs in above line
also modify /etc/fstab file accrdingly
Next time while booting this mount point will mount
Goodluck,
-USA..

Re: Largefile system
If you created this i.e.
newfs ???F vxfs ???o largefiles /dev/vg0_XX/rlvol0_XX
then you do or do not have to mount with the
-o largefiles option in the syntax? (Assume no entry in fstab.)

Re: Largefile system
That being the case, I always place the appropriate mount statement in fstab, then test it by mounting the filesystem using it's mountpoint name only (no options):
# mount /bigfiles
That tests everything about this mountpoint and verifies that it will return after a reboot. To easily see if the filesystem allows largefiles (and other features), get a copy of bdfmegs from:
ftp://contrib:9unsupp8@hprc.external.hp.com/sysadmin/coolscripts/
bdfmegs -v shows all the details (root needed). bdfmegs -l shows just local filesystems and anyone can run this. It is particularly useful as the output is always 1 line per mounpoint.
