Hi, I have the following doubt.
I install to new disks in my storage DS3400, expand it to my vmware LUN. Now I have 1.7 tera and after a have 1.1 tera.
But in the Vmware, I only see 1,1 tera. Then a I click in the storage and has the option to extend the free space, but it will destroy all my files.
Isn there any maner to do it without lose my vms ?
What is the right process to do it ?
It was better create a new LUN... not extend the existing one... Cause ESX 3.x does not have the "grow" function.
You have to extent the VMFS manually...
First create the new partition with fdisk /dev/sdX (change X with your right name, probably 'a')
Create a new primary partition (number 2) and change the type with fd (if you do not know how fdisk work, see on some Linux manual)
Then format the new partition (maybe is not necessary) with:
vmkfstools -C vmfs3 -S ExtentLUN vmhbaY:0:W:2 (where vmhbaY:0:W is your LUN name in ESX)
Finally extend the exisiting VMFS datastore:
vmkfstools -Z vmhbaY:0:W:2 vmhbaY:0:W:1
