I'm new to linux so this might be a dumb question. I've installed RHEL5 on VMware ESX 3.0 server. According to LVM, I have one physical disk with one Volume group and 2 logical volumes. I added a second disk drive using VMware and it shows up fine in LVM. My question is how do I make this new drive part of the Volume group so when I open the filesystem it will show more free space available due to the additional hard drive. Yes, I know how the use VMware to expand the size of the first drive but I also want to know how to do it with LVM. Thanks in advance for your help.

Code:

pvcreate /dev/sdx0

vgextend Volume_Group_Name /dev/sdx0

lvextend --size +10G Volume_Group_Name/Logical_Volume_Name #provides extra 10 gigs out of new pool size. OR

lvextend --extents 90%FREE Volume_Group_Name/Logical_Volume_Name #makes the logical volume size 90% the size of the volume grolup



#(assuming filesystem is ext) and you did a fsck.

resize2fs /dev/mapper/Volume_Group_Name/Logical_Volume_Name

Note: sometimes you cannot assign all the extents as the logical volume has been set to using contiguous extents - you can turn this off although you lose file system performance from doing so. To turn it off.

Code:

lvchange -C n Volume_Group_Name/Logical_Volume_Name

#if you turn it off its unlikely you can set it back.

That works really nice!! Thanks for your help!!!!!!!!!

you can also use system-config-lvm. It's all graphical
