From TritonDataCenter/illumos-kvm#14.

I was trying to change the size of a VM's disk with the following JSON:

{
"update_disks": [
{
"path": "/dev/zvol/rdsk/zones/bc1ff79e-2501-4ab1-916f-f8ab8597fb54-disk0",
"size": 102400
}
]
}

and the update failed with:

Successfully updated VM bc1ff79e-2501-4ab1-916f-f8ab8597fb54

This appears to happen when I try to re-size any KVM disks.

This issue has change how it manifests. This still holds true:

http://www.listbox.com/member/archive/184463/2014/06/search/dXBkYXRlX2Rpc2tz/sort/time_rev/page/1/entry/0:2/20140610082552:5A4AD1A0-F09A-11E3-A553-A68788328651/

it seems that vmadm refuses to update size despite it being documented as updatable. Is this a documentation or a implementation bug?

testing problem solved.
fifo does not resize zvol when we update vm via vmadm, and it not failed.
before update disks for kvm - need to resize zfs volsize
at first i did without zfs volsize, only by vmadm, and disk stay with old size.

May be we need to resize not with vmadm?
If at first i have resized zfs volsize, we need only reboot vm (kvm) to get effect for disks.
Vmadm updates disk without vmadm update -f

no need vmadm update to update disks
to take effect we need to reboot (for RHEL kernels), Gentoo doesn't need reboot to take effect.

that's right. at the beginning you need to update zvol size zfs set volsize, or vmadm maintainers need to updated vmadm to work with zvol and resize disks. In RHEL6 partprobe was broken and you can't resize root partition without reboot.

Updating volsize works, but I also had to manually update refreservation as it was not automatically updated as the zfs manpage would suggest. I would imagine any fix to vmadm should update both properties to remain consistent with creating a new zone.
