Hi Ron,
I did the same but made a copy of the agent properties file before hand on the
KVM hosts.
So to roll back I restored the management server and db servers.
I then did apt-get remove cloudstack-agent cloudstack-common on the KVM host.
Finally apt-get install cloudstack-agent cloudstack-common and copied back the
agent properties file.
The reason I know its agent related I tried starting the SSVM before rolling
back the agent, exact same error message.
"Secondary Storage Vm creation failure in zone [xxxx]. Error details: Unable to
allocate capacity on zone [1] due to [null]."
After rolling back the agent it worked fine.
I spent hours going through the logs but there is nothing that stands out so
gave up.
Thanks
Ian

Ian:
I wish mine was that simple. I did a dnf remove cloudstack-agent
cloudstack-common on the kvm host before I upgraded the agent to 4.21. I had no
guests running on it when I went through the process.
