# mount /dev/vg01/oracle /data
# vgdisplay vg01

Did it occur to you to actually READ THE man PAGE for lvextend before posting?

from man lvextend:

-l le_number Increase the space allocated to the logical
volume, specified in logical extents.
le_number is a decimal value greater than the
current number of logical extents.

le_number must be at least 1 and no greater
than a volume group version-dependent
maximum; use the lvmadm command to determine
the maximum number of logical extents for the
volume group version.

One, and only one, -l, -L, or -m option must
be supplied.

So you told the command to *extend* the LV to 3749 extents which is smaller than it currently is. Figure out how many extents equals 100GB and use that instead...

or to spell it out for you:

lvextend -l 6400 /dev/vg01/oracle

Please please please stop what your working on and spend some time reading the manuals

Try lvextend -L 102400m /dev/vg01/oracle

and then if you have onlinejfs

fsadm -b 102400m /mount_point

Please give me the command for now.... I will research on it after I have given the system

I thought

lvextend -L 102400m /dev/vg01/oracle

was pretty explicit.
