Eucalyptus allows volume creation beyond the limit set in the configuration

Status changed to 'Confirmed' because the bug affects multiple users.

While the UI itself does not clearly state the units of this setting, you can see it in the code in clc/modules/core/src/main/java/edu/ucsb/eucalyptus/cloud/entities/StorageInfo.java:

       @ConfigurableField( description = "Total disk space reserved for volumes", displayName = "Disk space reserved for volumes" )
        @Column( name = "system_storage_volume_size_gb" )
        private Integer maxTotalVolumeSizeInGb;

So the unit is GB, meaning that a value of "6000000" is approximately 6 Petabytes. I am guessing you were specifying this assuming that it was a smaller unit.

Then may I suggest this is still a bug but the bug is in the GUI. On the same browser panel for UEC configuration, above the entry field this bug report discusses, are other entry fields that specify "(MB)" or "(GB)" after the text. The text for this field should be modified so someone else does not make the same assumption that we did. That assumption was that the units were the same as the entry field right above it. That field being "Max volume size:". Therefore I would also suggest that, at the least, both field display names should have units added to the end of them so it looks like this:

Max volume size (MB):
Disk space reserved for volumes (GB):

That is, unless you tell me that max volume size is also in GB?

I did confirm that the units for the Max volume size is also GB. The GUI should be updated.
