| Neha Ojha | 2020-04-30 21:38:51 UTC | Doc Text | Cause: The earlier default value of bluestore's minimum allocation size(min_alloc_size) was 16K for SSDs. Consequence: RGW or CephFS store small objects and files as individual objects in rados. Objects smaller than bluestore's min_alloc_size(16K) use much more space than required. Fix: Change default value to 4K. Result: No performance implication with better space utilization. | |

Previously, objects smaller than Bluestore's default minimum allocation size (min_alloc_size) of 16KB used much more space than required. This happened because the earlier default value of Bluestore's min_alloc_size was 16K for solid state devices (SSDs). Currently, the default value of min_alloc_size is now 4KB. This enables better use of space with no impact on performance. |
