When working with etcd, you might encounter the error message: etcdserver: alarm not activated
. This indicates that an attempt to activate an alarm in etcd has failed. Alarms in etcd are used to notify administrators of certain conditions, such as low disk space or cluster health issues.
The error etcdserver: alarm not activated
