= Understanding node maintenance mode
|
|
|
|
Placing a node into maintenance marks the node as unschedulable and drains all
|
|
the virtual machines and pods from it. Virtual machine instances that have a
|
|
`LiveMigrate` eviction strategy are live migrated to another node without loss
|
|
of service. This eviction strategy is configured by default in virtual machine
|
|
created from common templates but must be configured manually for custom
|
|
virtual machines.
|
|
|
|
Virtual machine instances without an eviction strategy will be deleted on the
|
|
node and recreated on another node.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
Virtual machines must have a PersistentVolumeClaim (PVC) with a shared
|
|
ReadWriteMany (RWX) access mode to be live migrated.
