> The lowRedundancyBucketCount statistic is not maintained properly when multiple members are stopped and restarted
> A test where multiple members are stopped simultaneously so that all copies of a bucket are offlineshows the numBucketsWithoutRedundancy metric not set properly:
> Initially:
> {noformat}
> (2) Executing - show metrics --categories=partition --region=/rewards
> Category | Metric | Value
> --------- | --------------------------- | ------
> partition | putLocalRate | 0.0
> | putRemoteRate | 0.0
> | putRemoteLatency | 0
> | putRemoteAvgLatency | 0
> | bucketCount | 226
> | primaryBucketCount | 113
> | numBucketsWithoutRedundancy | 0
> | totalBucketSize | 200000
> | averageBucketSize | 221
> (3) Executing - show metrics --categories=partition --region=/customer

> | numBucketsWithoutRedundancy | 0
> | totalBucketSize | 20000
> | averageBucketSize | 22

> After stopping 2 members (of 4):
> {noformat}
> (2) Executing - show metrics --categories=partition --region=/rewards
> Category | Metric | Value
