A. Adding Hard disk
1. Checking current mount points drives

2 . Listing drives

Disk /dev/xvdb doesn't contain a valid partition
table
3. Creating Partion
[root@SERVER
~]# fdisk /dev/xvdb
The
number of cylinders for this disk is set to 52216.
There is
nothing wrong with that, but this is larger than 1024,
and could
in certain setups cause problems with:
1) software that runs at
boot time (e.g., old versions of LILO)
2) booting and partitioning
software from other OSs
(e.g., DOS FDISK, OS/2
FDISK)
Command (m for help): m
Command action
a toggle a bootable flag
b
edit bsd disklabel
c toggle the dos
compatibility flag
d delete a
partition
l list known partition types
m print this menu
n add a new
partition
o create a new empty DOS
partition table
p print the partition
table
q quit without saving changes
s create a new empty Sun disklabel
t
change a partition's system id
u change
display/entry units
v verify the
partition table
w write table to disk and
exit

B. Adding in OVS cluster :
/opt/ovs-agent-2.3/utils/repos.py -l
fdisk /dev/sdb
Check :

C.Adding
VM manger:
[root@ecmtest running_pool]#
/opt/ovs-agent-2.3/utils/repos.py -l
[ * ]
8b7c78d0-1578-41ce-b988-2c5ff686c12c => /dev/sda3
[
] 94ef36a3-6221-46c6-a68d-ae5ff8f4b1c8 => /dev/sdb5
Add
the files in newly created
/var/ovs/mount/94EF36A3622146C6A68DAE5FF8F4B1C8
