4.2.1. Editing node.cfg
This section discusses how to configure a DX Storage cluster node by manually editing /caringo/
node.cfg.
Note
A failsafe timer mechanism is included in the DX Storage startup process that will restart
the boot process if the boot error screen displays for longer than 15 minutes. This reboot
is intended to compensate for temporary network conditions and will be canceled if an
administrator uses a keyboard on the console. Multiple reboots in a row indicate there
might be a problem with the system configuration, in which case you should check the
syslog server for errors.
To manually edit /caringo/node.cfg using any text editor on the Windows, Mac, or Linux
platforms:
1. Using a text editor, open /caringo/node.cfg on the USB flash drive.
2. Make sure to set the parameter vols = all.
This parameter causes DX Storage to use all available volumes on the node. For more
information, see
3. Set other configuration parameters as desired using the guidelines discussed in the appendix on
node configuration in the DX Object Storage Administration Guide.
4. Make sure a valid license.txt file is located in the /caringo directory.
5. Set the cluster configuration parameter to name of your cluster. Dell strongly recommends you
use an
IANA-compatible domain
To prevent confusion, both in viewing the cluster from the administration console and
downstream in applications like DX Content Router that might analyze the source cluster, Dell
highly recommends that all nodes in the cluster be configured with the same cluster name.
6. Boot the DX Storage node from the configured USB device.
If your node boots from a USB flash drive, make sure to safely unmount or stop the USB flash
drive from the computer after configuration editing has been completed. If the flash drive is simply
unplugged without doing this, the changes might not be saved to the node.cfg file.
4.2.2. Storage Volume Configuration
DX Storage reads the vols parameter from the node and/or cluster configuration files to determine
which disks may be used for content storage. As shipped, DX Storage has a dummy value that
prevents unexpected formatting of a node's disks. An administrator must edit the vols parameter
and replace the dummy value with the keyword all or with a list of disks that DX Storage can use
for storage.
The easiest way to use all disks for content storage in a DX Storage node is to set the vols
parameter as follows:
vols = all
