• aerospikeConfig cannot be empty
• aerospikeConfig.namespace cannot be null or empty
• ca-path in TLS config not allowed, Only ca-file is allowed
• Strong consistency mode not yet supported
• Warm restart only supported for configuration change with newer versions of Aerospike container image

When updating a cluster

The following restrictions apply to an already deployed cluster:

note

• Storage.Volumes config cannot be updated
• MultiPodPerHost cannot be updated
• Cluster security config flag "enable-security" cannot be updated after the first deployment
• TLS config cannot be updated. See Manage TLS Certificates for info on how to rotate TLS certificates.
• aerospikeConfig.namespace.replication-factor cannot be updated, unless using Aerospike version 6.0 and later, and an AP (non-strong-consistency) namespace
• Persistent Aerospike namespace cannot be added dynamically
• Namespace storage device cannot be resized. No new storage device can be added

These values cannot be given in aerospikeConfig in yaml config file. These are fixed or determined at runtime.

• service.node-id
• service.cluster-name
• network.service.access-address
• network.service.alternate-access-address
• network.service.tls-access-address
• network.service.tls-alternate-access-address
• network.heartbeat.mode

Cannot be updated

The following values cannot be changed after the first deployment of a cluster

• network.service.port
• network.service.access-port
• network.service.alternate-access-port
• network.service.tls-port
• network.service.tls-access-port
• network.service.tls-alternate-access-port
• network.heartbeat.port
