8.4. Configuring Resource Relocation Modes for Nodes Participating in S3 or iSCSI Export¶
Important
Follow instructions in this section only if you use Virtuozzo Storage with GUI management in the scenario described below. Otherwise skip this section.
If you use Virtuozzo Storage with GUI management and have assigned the iSCSI network role to a node’s network interface in the Virtuozzo Storage management panel (see Network Interface Roles), high availability is automatically enabled for virtual machines, containers, and iSCSI targets on this node in the round-robin resource relocation mode.
If you use Virtuozzo Storage with GUI management and have joined a node to an S3 cluster in the Virtuozzo Storage management panel (see Creating the S3 Cluster), high availability is automatically enabled for virtual machines, containers, and S3 resources on this node in the round-robin resource relocation mode.
Note
All resource relocation modes are described in Configuring Resource Relocation Modes.
If you are fine with the round-robin mode, you do not need to configure anything else on the node. If, however, you want to change the resource relocation mode, e.g., to DRS, log in to the node via SSH, and run the hastart script as described in Enabling and Disabling High Availability for Nodes.
After executing the script, the HA mode will automatically change to DRS. If you need to change it again, follow the instructions in Configuring Resource Relocation Modes.
