How to turn on largefile support for a filesystem:

HP-UX 10.20: How to turn on largefiles:

/usr/sbin/fsadm -F hfs -o largefiles /dev/vg02/lvol1

or for vxfs:
/usr/sbin/fsadm -F vxfs -o largefiles /dev/vg02/rlvol2

snevada / # fsadm -F hfs /dev/vg00/lvol7
file system : /dev/vg00/lvol1
magic number : 95014

for volume group vg20, I entered the following in /etc/fstab,

/dev/vg20/lvol1 /cddump vxfs rw,suid,largefiles,delaylog,datainlog 0 2

but seems didn't work.

Pls look at the attached file, bdf of file systems.

Pls suggest, how to make sure everything is ok.
(after reboot)

Hi:

Your 'bdf' shows /cddrump is mounted and your /etc/fstab entry (as posted) is correct. What problem do you think you still have?

HI James,
Thanks for your input.

Actually, after creating /cddump in vg20, entered the posted entry in /etc/fstab,
and bdf, it was showing /cddump but when I rebooted the machine, it just disappeared, may be I thought something wrong in /etc/fstab,

bdf showing /u01 /u02 /u03 /u04 and /cddump
which I had just created, does it mean everything is ok, Can I reboot the machine now.

I yet have to enter entries in /etc/fstab for /u01 ... /u04. Can I enter the same as /cddump?

Please ...

Regards
Shah

hi shabaz

if you have configured the uxx like cddump, you can copy without problem.

For test, umount /cdddump, correct fstab and run "mount -a".

after with bdf you must see all file system

Hi,
After rebooting the system, all vgs except vg00 are deactivating.

I just activated all the vgs and now its ok.

So how to keep all the vgs activated after rebooting the machine?

Please ...
Thanks

Hi (again):

Make sure that AUTO_VG_ACTIVATE=1 is specified in your /etc/lvmrc configuration file. See the comments therein.

Hi,
For aito vg activation edit /etc/lvmrc and put
AUTO_VG_ACTIVATE=1

#vi /etc/lvmrc
AUTO_VG_ACTIVATE=1

[Shabaz]

Yes the value for AUTO_VG_ACTIVATE
was 0, now its ok

Once-again thanks lot, everybody.
