Checking Redundancy in Partitioned Regions
Under some circumstances, it can be important to verify that your partitioned region data is redundant and that upon member restart, redundancy has been recovered properly across partitioned region members.
You can verify partitioned region redundancy by making sure that the
numBucketsWithoutRedundancy statistic is zero for all your partitioned regions. To check this statistic, use the following
gfsh>show metrics --categories=partition --region=region_name
gfsh>show metrics --categories=partition --region=posts Cluster-wide Region Metrics --------- | --------------------------- | ----- partition | putLocalRate | 0 | putRemoteRate | 0 | putRemoteLatency | 0 | putRemoteAvgLatency | 0 | bucketCount | 1 | primaryBucketCount | 1 | numBucketsWithoutRedundancy | 1 | minBucketSize | 1 | maxBucketSize | 0 | totalBucketSize | 1 | averageBucketSize | 1
If you have
start-recovery-delay=-1 configured for your partitioned region, you will need to perform a rebalance on your region after you restart any members in your cluster in order to recover redundancy.
If you have
start-recovery-delay set to a low number, you may need to wait extra time until the region has recovered redundancy.
