Can't upload image larger than 32GB

By default the max image size that could be uploaded to glance should be 32GB, so you can update this limit with the following command:

cmsh
[shadow-head]% openstack
[shadow-head->openstack[default]]% settingsquota                                              
[shadow-head->openstack[default]->settings:quota]% set maxsingleimagesize 100GB
[shadow-head->openstack*[default*]->settings:quota*]% commit

Can't create snapshots

The problem was due to timeout uploading the image on glance, so we increase this timeout to 120s and change also the defaults from 4s to 20s.

cmsh
[shadow-head]% device use master 
[shadow-head->device[shadow-head]]% roles 
[shadow-head->device[shadow-head]->roles]% use haproxy

Cannot Create new CaaS nodes

Again a timeout issue:

Cannot find external network

This is a case when you renamed Bright's external network.

Bright's external network's name is hard coded. In order to change it edit the following file:

/cm/shared/apps/cm-openstack-caas/bin/ExternalNet.py

Search and replace "bright-external-flat-externalnet" with the name of the network you just created.

You can retrieve the openstack network name with the command (Update <NETWORK_NAME> accordingly):

cmsh -c "network; use <NETWORK_NAME>; get openstackphysicalnetworkname"
