Description
When some nodes disconnect from the COS network and are marked as suspended (by an operator), they may remain as offline even after they are apparently online. This happens arbitrarily because it is a timing dependent issue.
Workaround
Force cluster re-synchronizations by running cosmod --force-synchronization.
Fix
The described scenario should not happen. Offline nodes that have been manually marked as suspended will appear online after rejoining the cluster.
