Using the pattern determined in network planning for the site, this This scsctl initialization step will build builds a custom configuration file for DHCP and restart restarts the service using the pattern determined in Network Planning for the site. Changes in the configuration file specify pools specifies the pool and ranges which DHCP is to manage, as well as other DHCP response data to be used with PXE booting storage nodes.
...
To configure DHCP, refer to the following steps:
...
The Swarm network requires an upper or lower (or both) reserved range defined to configure DHCP. At least one of these parameters must be provided.
| The number of IP addresses to reserve in the lower subnet range (default is 0). |
| The number of IP addresses to reserve in the upper subnet range (default is 0). |
For example, set the DHCP reserve lower range.
| Code Block | ||
|---|---|---|
| ||
scsctl init dhcp --dhcp-reserve-lower |
...
Set the minimum size of the disk supported by the Swarm cluster. For example, the Swarm cluster supports a minimum of 16 GB disk size.
| Code Block | ||
|---|---|---|
| ||
scsctl storage config set -d "disk.minGB=16" |
...
Enable the nodeExporter for Prometheus.
| Code Block |
|---|
scsctl storage config set -d "metrics.enableNodeExporter=true"
scsctl storage config set -d "metrics.nodeExporterFrequency=120" |
