    • Data checksums can be turned on with --data_csum_type crc32c for new OSDs
    • Checksum block size can be configured
    • inmemory_metadata now also affects keeping checksums in memory
  • Linux page cache I/O caching support which can be enabled separately for data, metadata (including checksums) and journal (O_SYNC instead of O_DIRECT)
  • Details here
  • Backwards compatibility is preserved, you can use new OSDs with old disks

Release also includes bug fixes from 0.9.6.

0.9.6 is moved to “-oldstable” repositories and will be available for some additional time.
