Description
Build: 7.1.0 build 1787
Not able to fetch any events after hitting "Unable to automatically failover nodes" state
Steps:
- Four node cluster
- Couchbase bucket with replica=0
- Stop memcached on one node (here 172.23.105.212)
- Wait for auto failover threshold to reach, which results in,
Could not automatically fail over nodes (['ns_1@172.23.105.212']). Would lose vbuckets in the following buckets: ["default"]
Observation:
After hitting this state, we are unable to retrieve any events happened after this.
Note: Events happened prior to this is still accessible.
