Hedvig Storage Cluster Nodes are added either in batch mode or interactively.
Here are a few notes about adding storage cluster nodes:
-
It is recommended that three storage cluster nodes be added at a time. However, any number, including only one, can be added at a time.
-
The storage cluster nodes to be added must have the same hardware configuration as the existing storage cluster nodes.
-
All storage cluster nodes must be set up with FQDNs:
hostnamectl set-hostname a.b.com -
Adding storage cluster nodes is a non-disruptive operation and does not impact anything running in the cluster
