Before the release of SMU 1.2, it was not possible to use SMU to clone a distributed database between two nodes of the same clustered ZFS Storage Appliance.

When the customer tried to create a SMU backup against the 2nd head, he received an error:

"the number of remote shares is greater than the number of shares to backup"

Creating backup failed @ --- TASK FAILED --- @ The number of remote shares is greater than the number of shares to backup.

If we connect to ZFS2, we realized that the resolved IP address does not match the address configured on the appliance.

DNS resolution is not working

Solution

Modify local /etc/host on the SMU client to point to the correct appliance and then recreate the SMU account configuration.
