am i missing something, the web client is offline if i shut the appliance down.
i noticed that i have a snapshot which was causing greyed disks.   if i change them i get:

Access to resource settings on the host is restricted to the server that is managing it: ''.

but seems to have increased the disk...
In case of have only one option...delete the snapshot ,and extend it..
CHI-LTDAuthor Commented:
yes i have already done this.

in a catch 22 whereby i cant edit the vm as it needs to be offline..
given up on this one.  hopefully vmware appliance design is better in v6 in terms of not running out of space.

it seems to me you have all what you need to do what you ask, or am I missing a point ?
Don't give up !  :-)

If I understand correctly your VMDK sizes were greyed out. Either because you had snapshot or were using the old vsphere client.
So it seems you have deleted the snapshot and extended your VMDK number 6 on your vcenter 6 appliance :

Your comment :
yes i have already done this.

So what is your issue right now, if you use the virtuallyghetto link you first gave in your question ?

I don't understand your sentence :
in a catch 22 whereby i cant edit the vm as it needs to be offline..
But my english is far from perfect...

well i managed to upgrade the disk after deleting the snapshot, or it appears to have done, as it displays a larger disk in the VM properties, but i'm not so sure.  
I think i need to down the VM in order to increase the disk but if i do that then i cant manage the VM as its off.
Mr TorturSystem EngineerCommented:
If it displays the new size in VM settings it means it has been done correctly.
As stated by your link you don't need to shutdown the vCSA 6 VM.

From your link :
In the example below, I will walk through the process of increasing the DB VMDK from the existing 10GB to 20GB while the vCenter Server is still running.

Mr TorturSystem EngineerCommented:
This command ran on the vCSA ?
vpxd_servicecfg storage lvm autogrow

well it should work.
Is your vCSA VM in a fine state ? Try to reboot it and try again the command eventually.
CHI-LTDAuthor Commented:
will do
