-----------------------------------------------------------------------
Looks like there's a codepath in getResizeScriptType (unchanged in these
commits) that can leave type as null, in the very unlikely circumstance that an
unknown storage pool type is registered with KVM (e.g. someone somehow
registers something like StoragePoolType.ZFS and somehow creates a volume on it
before trying to resize). It should probably be fixed, and can be an issue for
developers who create new storage pool types, but I don't believe it is a
blocker for a bugfix release.

> Key: CLOUDSTACK-6181
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6181
> Project: CloudStack
> Issue Type: New Feature
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Hypervisor Controller, Storage Controller, UI
> Affects Versions: 4.4.0
> Environment: KVM/libvirt/CentOS, Xenserver
> Reporter: Nux
> Labels: disk, resize, template
> Fix For: 4.4.0
>
>
> Rationale:
> Currently the root size of an instance is locked to that of the template.
> This creates unnecessary template duplicates, prevents the creation of a
> market place, wastes time and disk space and generally makes work more
> complicated.
> Real life example - a small VPS provider might want to offer the following
> sizes (in GB):
> 10,20,40,80,160,240,320,480,620
> That's 9 offerings.
> The template selection could look like this, including real disk space used:
> Windows 2008 ~10GB
> Windows 2008+Plesk ~15GB
> Windows 2008+MSSQL ~15GB
> Windows 2012 ~10GB
> Windows 2012+Plesk ~15GB
> Windows 2012+MSSQL ~15GB
> CentOS ~1GB
> CentOS+CPanel ~3GB
> CentOS+Virtualmin ~3GB
> CentOS+Zimbra ~3GB
> CentOS+Docker ~2GB
> Debian ~1GB
> Ubuntu LTS ~1GB
> In this case the total disk space used by templates will be 828 GB, that's
> almost 1 TB. If your storage is expensive and limited SSD this can get
> painful!
> If the root resize feature is enabled we can reduce this to under 100 GB.
