Update Aerospike Clusters on Kubernetes From Aerospike Version 6.x or Later

Check if your current Server version has special upgrade considerations before you upgrade or downgrade.

When upgrading Aerospike server cluster from 5.x or prior to 6.x or later (or downgrading from 6.x or later to 5.x or prior), the Operator wipes each namespace storage Block volumes and removes namespace storage files in case of Filesystem volumes. PMEM storage volumes are not wiped.

See WipeMethod configuration for details.

Special upgrade considerations:

• 6.4 or later
• 6.3 or later
• 6.1 or later
• 6.0 or later

caution

When using blkdiscard as the wipe method, be sure the drive deterministically returns zeros after TRIM (RZAT). Check with your hardware provider or cloud provider to find out if this is the case. If you are unsure, it is safer to wipe the device using dd as the wipe method.

To upgrade the cluster to 6.4.0.0 change the spec.image field to use 6.4.0.0 Aerospike image. The following example shows an upgrade using blkdscard wipe method.
