Adding the Software
Add the storage software bundle for the cluster.
scsctl repo component add -f {storage component tarball file}
Prompting for Settings
Certain component settings ship without defaults, as these settings are unique to the environment in which Swarm runs. The CLI prompts for the component values while adding the software. If any of these settings are skipped, the CLI prompts again during the finalization of Swarm configuration settings.
disk.volumes
This setting governs which volumes on the chassis Swarm storage will use. Enter all when prompted for the disk.volumes setting’s default value unless instructed by DataCore.
cip.multicastEnabled
Available since: Swarm 15.0
This setting controls the use of multicast for Swarm Storage node intercommunication. Prior to Swarm v15.0, multicast was required. For clusters already using multicast, it is advised to continue using it as changing the setting value requires a full, non-rolling cluster reboot. New installations may require a special network configuration to support multicast. Therefore, do not use multicast for new installations. If not sure about enabling multicast, please contact DataCore Support.
Prompting for the Cluster/Group Name
Once the software is added, provide a group name when prompted to define a cluster for Swarm Storage nodes.
The group name is used as the cluster name. The group description is optional and for human administrator purposes.
Example:
$> scsctl repo component add -f swarm-scs-storage-15.0.0.tgz Missing setting: storage/disk.volumes Missing setting: storage/cip.multicastEnabled The following setting(s) require a default value: disk.volumes [type: str] (Required. Specifies the volume storage devices for Swarm to use. Valid entries: all, or a space-separated list of Linux volume identifiers, such as /dev/sda, /dev/sdb. all (recommended) is required for hot plugging and lets Swarm to use all volumes larger than disk.minGB. If a node is shut down longer than disk.obsoleteTimeout, all of its volumes are stale and cannot be used unless you force a volume remount by adding the :k (keep) policy option modifier. To specify the size, add a modifier with units: vols1:100m vols2:250g.): all cip.multicastEnabled [type: bool] (Whether or not multicast should be used for communication within Swarm.): False added: storage - 15.0.0 (15.0.5) Please enter a name for the group (FQDN format encouraged) - Required to be able to boot instances of "storage": a.storage.cluster Please enter a description for the group (purpose, etc).
