Hello there,
in a HA-Cluster there is something strange. While installing Update on one paused host, there is a nother one which will be evicted from the cluster.
On this special host the failover cluster feature was removed and installed but the host was evicted again. The cluster validation test say´s there is nothing wrong. some lines from the clusterlog here:
