SR_BACKEND_FAILURE44 Insufficient Space
Matthew, sorry to hear about your troubles. I will try my best to help you out here on the forum but I do recommend that if you have a support contract with Citrix then better report an incident with them as well.
Please answer the following questions:
1. At the moment, is any SSVM running (agent status is reported Up) in the zone you are deploying the VMs in?
2. Are you using storage tags?
3. I need more information about the available space, both in the DB and as reported in mgmt server logs during deployment. How can you share that information?
