how can i make this kind of system?

[gary guo]

the server's harddisk still have unused space:
--- Physical volumes ---
PV Name /dev/dsk/c3t0d0
PV Status available
Total PE 17005
Free PE 7005


i wanna build a new filesystem which is /dev/vg02/lvol2 ,it will mount on /oradata ,it is about 20G, and i wanna this filesystem isnt restricted by 2G which is the biggest file in the system, how can i do it ?

Fire up SAM, go into "Disks and Filesystems", select "Logical Volumes", then, under actions, select Create. As you go through the create menu, there are options to allow large files, specify the mount point, etc.

Hi Gary,

It is fairly simple. I'm not sure I understand if your logical Volume has already been created or not, but in any case, from the start this is what it would look like :

#lvcreate -n lvol2 -L 20000 vg02
#newfs -F vxfs -o largefiles /dev/vg02/rlvol2

and when you mount your filesystem

# mount -o largefiles /dev/vg02/lvol2 /oradata

[T G Manikandan]

Assuming this disk is in vg02 and the lvol2 does not already exist on vg02

#lvcreate -L 20000 /dev/vg02/lvol2

#mkfs -F vxfs -o largefiles /dev/vg02/rlvol2

#mkdir /oradata
#mount -F vxfs -o largefiles /dev/vg02/lvol2 /oradata

Make sure that you update the /etc/fstab for the new file system with the largefiles option

[Bill Hassell]

To use all the available extents (7005 are left in the above example), use:

lvcreate -l 7005 -n lvol2 vg02
newfs -F vxfs -v -o largefiles /dev/vg02/rlvol2
echo "/dev/vg02/lvol2 /oradata vxfs rw,nosuid,largefiles,delaylog 0 2 >> /etc/fstab

Then to test the result:

mount /oradata

This is recommended (add to fstab, then mount without the source lvol) to check the entry in fstab.

I need to put something in to refresh myself

#lvcreate -L 20000 -n lvol2 /dev/vg02

[Bill McNAMARA_1]

fsadm -F vxfs -o largefiles

to do it after if you have onlineJFS installed.

note the -L option of lvcreate is MB size
The -l option is number of PE. The PE Size is by default 4M, so check it with your PVDisplay.
