Grew VM disk, moved and grew partition, VM doesn't see changes.


Mar 11, 2021

I have a Windows Server 2019 VM that I'm trying to give some more free disk space.

I shut the VM down, and grew the virtio disk by 60Gb

Then I booted the VM off a GParted ISO, moved the Windows rescue partition to the end of the disk so the free space was contiguous, and grew the Windows main partition.


Booting the VM into Windows Server 1019, I don't see the disk changes. Disk manager still see the rescue partition where it was, and the non-contiguous free space at the end of the disk.


Booting off an Ubuntu ISO, Disks shows the partition changes applied.


Can anyone explain what's going on here?

We're running 7.0.11 with local zfs pool storage only.
Found a solution here after more desperate searching:

After resizing and moving partitions, boot the VM, then shutdown with:
shutdown -s -t 0

The next restart of the VM should show the changes as applied.
