Downgrade from Database 7.2

This page provides important information about performing a downgrade from Database 7.2.

Overview

If active-rack has been enabled in Database 7.2, it must be disabled on all nodes before downgrading.

Disable active rack for Available and Partition-tolerant (AP) mode

  1. Use asadm to disable active-rack in AP namespaces:

    Admin> enable
    Admin+> manage config namespace ns-name param active-rack to 0
    ~Set Namespace Param active-rack to 0~
             Node|Response
    10.1.0.1:3000|ok
    10.1.0.2:3000|ok
    10.1.0.3:3000|ok
    Number of rows: 3

  2. Recluster for your active-rack to take effect.

    Admin+> manage recluster
    Successfully started recluster

  3. Remove the active-rack line from aerospike.conf on all nodes before downgrading from Database 7.2.

Disable active rack for Strong Consistency (SC) mode

  1. Use asadm to disable active-rack in SC namespaces:

    Admin> enable
    Admin+> manage config namespace ns-name param active-rack to 0
    ~Set Namespace Param active-rack to 0~
             Node|Response
    10.1.0.1:3000|ok
    10.1.0.2:3000|ok
    10.1.0.3:3000|ok
    Number of rows: 3

  2. Recluster for your active-rack to take effect.

    Admin+> manage recluster
    Successfully started recluster

  3. Modify the pending roster changes.

    Admin+> manage roster stage observed ns ns-name
    Pending roster now contains observed nodes.

  4. Recluster again for changes to take effect.

    Admin+> manage recluster
    Successfully started recluster

  5. Remove the active-rack line from aerospike.conf on all nodes before downgrading from Database 7.2.
