The following restrictions are currently in place and apply to any cluster managed by the operator.
- aerospikeConfig cannot be empty.
aerospikeConfig.Namespacescannot be null or empty.

- Warm restart is only supported for configuration changes with Aerospike container image 6.0 and later.
- All flash requires the Aerospike pod to be run in privileged mode.
- Any strong consistency namespaces that exist on any given rack should also exist on all other racks. In other words, if a rack
R1has SC namespaces
N2, all other racks should also have SC namespaces
N2. This requirement affects only namespace names, so internal configurations can be different between identically-named namespaces on different racks.
- A cluster size less than the replication factor is allowed in AP mode but not in SC mode.
When updating a cluster
The following restrictions apply to an already deployed cluster:
Although they can't be updated in place, you can adjust Storage.Volumes, and Namespace storage using the workaround described here.
- Persistent storage volumes cannot be added, removed, or updated in the
strong-consistencyparameters cannot be changed in the
- The cluster security flag
enable-securitycannot be updated.
- TLS configuration cannot be updated. See Manage TLS Certificates for information on how to rotate TLS certificates.
- A persistent Aerospike namespace cannot be added dynamically.
- A namespace storage device cannot be resized. No new storage devices can be added.
- A simultaneous cluster scale-down and rolling restart is not supported in strong consistency mode. These must be done sequentially.
- Block device re-usage requires two update operations: one to remove the block device from a namespace, and a second to add the block device to a different namespace.
Cannot be set
These values cannot be given in aerospikeConfig in the YAML configuration file. These are fixed or determined at runtime.
Cannot be updated
The following values cannot be changed after the first deployment of a cluster
