Subject [jira] [Commented] (CLOUDSTACK-6181) Root resize
Date Mon, 10 Mar 2014 16:12:44 GMT

Marcus Sorensen commented on CLOUDSTACK-6181:
---------------------------------------------

I've added some debugging for both. I'll try to replicate them if I can find time, but the
debugging is checked in if you have time to test. I currently don't see a way you'd get that
error if your volume is in ready state or allocated state, so the error prints the actual
state now.

The code that checks requested rootdisksize vs template size also prints what sizes its comparing
now.

>             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.
