Hi, Can Ceph Bluestore in Luminous work with 2 replicas using crc32c checksum which is more powerful than hashing in filestore versions or do we still need 3 replicas for data integrity?
In our current Hammer-filestore environment we are using 3 replicas with HDD but planning to move to Bluestore-Luminous all SSD. Due to the cost of SSD's want to know if 2 replica is good or still need 3. Thanks, Pardhiv Karri
