I suggest to get rid of the ridiculous striping at all. Striping is a good idea if you hae physical disks and want to spread the load over all of them so that the overall response time of the (disk sub-)system gets better. It makes absolutely no sense at all with SAN disks (from the names of the hdisk devices i suppose you have an EMC storage).
To tell you the bad news up front: you will need a downtime to do this because it means deleting and recreating the LV. Still it is a good idea to do so because the further administration will be way easier once you did it.
I hope this helps.

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

NVD(4) BSD Kernel Interfaces Manual NVD(4)
NAME
nvd -- NVM Express disk driver
SYNOPSIS
To compile this driver into your kernel, place the following lines in your kernel configuration file:
device nvme
device nvd
Or, to load the driver as a module at boot, place the following lines in loader.conf(5):
nvme_load="YES"
nvd_load="YES"
DESCRIPTION
The nvd driver exposes NVM Express (NVMe) namespaces as disks to the kernel disk storage API. It depends on the nvme(4) driver for notifica-
tion of existing NVMe namespaces and submission of NVM I/O commands.
Device nodes from the nvd driver will have the format /dev/nvdX and are GEOM(4) disks which can be partitioned by geom(8). Note that device
nodes from the nvme(4) driver are not GEOM(4) disks and cannot be partitioned.
SEE ALSO
GEOM(4), nvme(4), geom(8), nvmecontrol(8), disk(9)
HISTORY
The nvd driver first appeared in FreeBSD 9.2.
AUTHORS
The nvd driver was developed by Intel and originally written by Jim Harris <jimharris@FreeBSD.org>, with contributions from Joe Golio at EMC.
This man page was written by Jim Harris <jimharris@FreeBSD.org>.
