Hp 11.0 [ largefiles nolargefiles]

[DK Raviraja]

We have HP 11.0. As we know it supports upto 128GB os single datafile.
I would like to know how the file system is created.

Is it with nolargefile or largefile.

In case If I have to switch over to LARGEFILE, what are the precautions to be taken. If iam right we can use fsadm command to switch.

Hi,

if you have NOT OnlinJFS you have to do:
umount
fsadm -F -o largefiles /dev/vgXX/rlovlX
fs_typ may be hfs or vxfs, check with fstyp /dev/vgXX/lvolX
If you have OnlineJFS:
fsadm -F -o largefiles
For creating:
newfs -F -o largefiles /dev/vgXX/rlvolX

Hi,

You can check the man pages for fsadm. To work on a specific filesystem type check fsadm_FStype(1M). It contains examples.

Hi:

As for precautions, just rememeber that old utilities like tar and cpio do NOT suport copying files > 2GB. They have inherent limitations that cannot and will not be overcome.

Hi Friends

I have enabled my Files system /dev/vg00/utemp to largefiles using SAM, after umounting the same. File System Type is VXFS.

When I tried to mount the same by checking 'Mount now' option in SAM, it is giving error Unable to Mount File system - Incompatible.....

What next

Hi,

try it by command line:
mount /dev/vg00/utemp

Hi,

Check the entry of your file system in /etc/fstab. The entry should have a largefiles option in it. Example:
My largefiles option is enabled on /DBCCFS2. It should have an entry like below on /etc/fstab:

/dev/vg07/dbccfs2 /DBCCFS2 vxfs log,nodatainlog,largefiles,rw,suid 0 2

FYI, the release notes in /usr/share/doc/10.20RelNotes or 11.00RelNotes documents filesystem capacity.

In addition, there is a large filesystem paper, /usr/share/doc/lg_files.txt. This paper documents how to convert to largefiles and vice versa.
