Storage Nodes

A storage node is operated with the sbctl storage-node commands. Most of what a node needs is automatic: an unavailable node is restarted by the control plane, and its logical volumes are served through their failover paths while it is gone. What is left are the deliberate operations, and the lookups needed before one is started.

Replacing a Storage Node	Choosing between a relocation and a replacement when hardware is exchanged.
Migrating a Storage Node	Moving a storage node onto a different host, keeping its identity.
Finding the Secondary Node	Determining which node holds the failover path of a logical volume.
Linux Block Device Operations	Day-2 operations specific to a cluster in the lblk mode.
