Hi,
Here are the steps you need to do (they should be fine, but
Let me know if you have any issues, and the associated error
Because I might have missed something):
Step 1. create a partition on your new disk:
# fdisk /dev/cciss/c0d1
Once within fdisk, type the following (what you enter is between <> )
Command (m for help): <n>
Command action
e extended
p primary partition (1-4)

Partition number (1-4):
<1>
First cylinder (1- ...): <press enter to select default>
Last cylinder ... : <press enter to select default>
Now, you will find yourself back at the main prompt. You will want to
now
Change the partition's ID to Linux LVM
Command (m for help): <t>
Hex code (type L to list codes): <8e>
<w> - to write the partition table.
Now you should be back in the shell.
Step 2. create a new physical volume:
# pvcreate /dev/cciss/c0d1p1 (I think this is what it should be if you
have only made one single partition on the new disk).
Step 3. Add your new physical volume to your existing volume group
# pvextend VolGroup00 /dev/cciss/c0d1p1
I think that should be vgextend
# vgextend -A VolGroup00 /dev/cciss/c0d1p1
Assuming the above worked, if you now type "vgdisplay -v", you should
see two
physical volumes at the bottom of the output, and an increase in
capacity of

Hello,
Firstly, please answer these two questions:
1. what do you see with this command:

2. How many volume groups do you have? (you can find this information
With the following command. The -v flag will give more verbose output

Subject: Adding new disk to volume group
Currently I'm using Red Hat Enterprise 4 that has two disk on a
Hardware Raid 1 (Smart Array 5i controller) that is setup in a Volume
Group
(VolGroup00) with the following logical volumes LogVol00, LogVol01,
LogVol02, LogVol03, LogVol04, and LogVol05. I recently added two
more
disks in our system/server (these are internal disks on a HP Proliant
DL380 g2) and set these disk as a Hardware Raid 1. Now I haven't used
Fdisk or nothing on these new disks.
Here's my question: How do I add the new disks to the already
existing Volume Group so that I can have more space on the Volume
Group. Being a
Raid1 I know your only adding one disk. Could someone send me the
exact commands to use?
