Hi all,
We are running 4.11.3 with a single zone, that zone is working without issue.
We are trying to add a second zone to the installation, and everything seems to
go well, except we are confused on how the SystemVM templates should be handled
for the new zone. The new zone has its own secondary storage (NFS). When
Cloudstack sees the new Zone, it attempts to provision a Secondary Storage VM.
However, it is unable to because the SystemVM Template doesn't exist on the new
secondary storage (NFS).
Are we supposed to pre-populate another copy of the SystemVM Template in the
additional zone and secondary storage? Or should cloudstack copy the existing
SystemVM Template (which is set as cross-zone) to the new zone for us? Here is
some detailed information:
MariaDB [cloud]> SELECT id,name,type,cross_zones,state FROM cloud.vm_template
WHERE name like '%systemvm-kvm%' AND removed IS NULL;
+-----+------------------------------+---------+-------------+----------+
| id | name | type | cross_zones | state |
+-----+------------------------------+---------+-------------+----------+
| 344 | systemvm-kvm-4.11.3 | SYSTEM | 1 | Active |
+-----+------------------------------+---------+-------------+----------+
MariaDB [cloud]> select id,store_id,template_id,install_path, download_state
from template_store_ref;
+-----+----------+-------------+------------------------------------------------------------------------+----------------+
| id | store_id | template_id | install_path
| download_state |
+-----+----------+-------------+------------------------------------------------------------------------+----------------+
| 666 | 1 | 344 |

Why in the template_store_ref table did cloudstack add a new row with
"downloaded" and missing a filename in the "install_path"?
The KVM host cannot mount the template on the new secondary storage, because it
isn't there yet (should cloudstack be copying that template from the existing
zone to the new one for us?):
