DX Object Storage Platform: Advanced Node Configuration

The Dell

DX Object Storage Platform provides configuration of cluster-wide parameters through the

TM

web-based management console on the DX Cluster Services Node (CSN). There are additional node

level configurations that are not supported through the web-based management console and require

advanced knowledge of the node configuration files located on the DX Cluster Services Node. This

document provides instructions on configuring the following advanced configurations through the node

configuration files:



Configuration of Sub-clusters



Configuration of Storage Nodes in archive mode

The target audience for this document is advanced DX Storage administrators and support teams.

All cluster-wide Storage Node configurations should be done through the CSN Console. The

configuration parameters are stored in a single configuration files (/var/opt/caring/netboot/content/

common.cfg) that is automatically generated. DX Storage also allows Storage Node level configuration.

Node level configuration is not supported through the CSN console. It requires manual editing of

configuration files located on the CSN. There is an individual Storage Node configuration file for every

SN in the cluster that can be modified to define custom configuration for each storage node.

The configuration file can be manually created and stored

individual Storage Node should be given the name of the Storage Node machine (MAC) address

(snMACAddress.cfg) and should be located in the /var/opt/caringo/netboot/content/nodeconfigs/

directory. Since the Mac address is not assigned until after the Storage Node has boot into the

the Storage Node configuration file cannot be created until after the Storage Node boots into the

cluster. To assist in creating the individual Storage Node (SN) configuration files, a list of all IP address

assignments and the associated Storage Node MAC address can be obtained by running the following

command line script:

# /opt/caringo/csn/bin/ip-assignments

To create custom config files for every known MAC address automatically run following command:

# for mac in `/opt/caringo/csn/bin/ip-assignments --macs`; do touch

/var/opt/caringo/netboot/content/nodeconfigs/sn$mac.cfg; done

Below is a summary of the steps for creating and updating the configuration file for a Storage Node:

1. PXE boot the SN.

2. Identify the SN MAC address and create the configuration file via the /opt/caring/csn/bin/ip-

assignments script

3. Modify the snMACAddress.cfg file for that SN.

4. Reboot the SN.
