Migrating Greenplum® cluster hosts to a different availability zone
All Managed Service for Greenplum® cluster hosts are located in the same Yandex Cloud availability zone. To move hosts from one availability zone to another, restore your cluster from a backup. During cluster recovery from a backup, specify a new availability zone.
Note
For clusters with hosts residing in the ru-central1-d availability zone, local SSD storage is not available if using the Intel Cascade Lake platform.
Specifics of migration in Yandex Data Transfer
If your cluster acts as an endpoint at data transfer using Data Transfer:
-
Make sure the cluster hosts are located in the
ru-central1-aorru-central1-bavailability zone; otherwise, the transfer will not operate correctly. -
If the transfer type is Replication or Snapshot and increment, restart the transfer after recovery from a backup. This way, it will get data about the cluster's new topology. You do not need to restart Snapshot transfers, as information about the new topology is provided automatically while activating them.
To restart a transfer, choose one of the two methods:
- Deactivate the transfer and wait for its status to change to Stopped. Next, reactivate the transfer and wait for its status to change to Replicating.
- Update any setting for the transfer or endpoint.
