Subject problem with vm volume resize
Date Wed, 20 Apr 2016 03:57:32 GMT
I have a cloudstack 4.2 installation with vmware 5.0 as the underlying hypervisor. I've resized
volumes in the past using the web UI, but have run into an issue where my resize attempt on
an existing win2k8 data volume failed. It is a resize from 50Gb to 100Gb, and I have enough
storage to do the resize.

When I attempt the resize, the UI returns 'unable to resize volume', and I find the following
error in the management server log:

2016-04-19 22:52:45,468 ERROR [vmware.resource.VmwareResource] (DirectAgent-88:wyo1-p1-c1-hv5.dsscorp.com,
job-641, cmd: ResizeVolumeCommand) Unable to resize volume

The vm in question has been in the cloud enviornment/production for 2+ years. It has a root
volume, and 3 data volumes. I'm trying to resize the first data volume.

I've seen some mention of issues like this with resizing volumes that were created from snapshots,
but that doesn't apply here.

Any thoughts on why my resize attempt is failing?
