[StarCluster] Error when I try to resize a volume

[Torstein Fjermestad]

Dear all,

I just tried to increase the size of a volume attached to a cluster. The
procedure I do is the following:

1) I first run the command:

starcluster listvolumes

to find the ID of the volume I want to resize.

2) thereafter I run the command

starcluster resizevolume <volume_ID> 20

as explained in the user manual.

However, this command resulted in the following error message:

AttributeError: 'VolumeCreator' object has no attribute '_snapshot'

Does this mean that I have to make a snapshot of the volume before I resize
it? In that case, how to I do this?

The "resizevolume" command also generated a crash report which I have
attached.

It would be very nice if someone could come up with ideas on how to
increase the volume size.

Thanks in advance for your help.

Regards,
Torstein Fjermestad
