I have a VM with 2 virtio-scsi disks (on FC).

If I try to do a resize of the boot disk (preallocated) from this menu:

1)

- select VM

- disks sub tab

- select disk

- edit

- edit virtual disk window

- extend size by X Gb

I get error about "not all VMs are powered down"

Instead if I do a resize of the same disk from this menu:

2)

- select VM

- edit VM

- find the line of the disk and select the "edit" button at the right

- edit virtual disk window

- extend size by X Gb

it works as expected, so without downtime

Is this expected?

Actually after 2) scenario, I had retried 1) and it works too this time.

During the first 1) that failed, I see this in engine.log:

But the VM is indeed up on all 3 attempts.... so I don't understand this message

 

On another VM, again with a disk configured as virtio-scsi, but configured as thin provisioned, both from 1) and 2) scenario I get:

c7service:

• Cannot edit Virtual Disk. Cannot edit Virtual Disk. Disk extension combined with disk compat version update isn't supported. Please perform the updates separately.

What does it mean "perform the updates separately"? I cannot online resize thin provisioned disks?

The VM has only one disk, BTW.

Thanks,

Gianluca
