Issue

Node configuration data loss can occur if certain boot environment variables are incorrectly set and the node is a member of a cluster and the node subsequently rebooted.

Same can occur with the following scenarios:

  • Unable to join new nodes to the cluster
  • New nodes were downgraded to match the existing cluster nodes
  • After downgrade one node reports:

sed: /var/etc/nsswitch.conf: No such file or directory
