.New generalized stretch cluster configuration for three availability zones Previously, there was no way to apply a stretch peer rule to prevent placement groups (PGs) from becoming active when there weren’t enough OSDs in the acting set from different buckets without enabling the stretch mode. With a generalized stretch cluster configuration for three availability zones, three data centers are supported, with each site holding two copies of the data. This helps ensure that even during a data center outage, the data remains accessible and writeable from another site. With this configuration, the pool replication size is 6 and the pool min_size is 3.
