v0.83 released [feedly]

v0.83 released
// Ceph

Another Ceph development release! This has been a longer cycle, so there has been quite a bit of bug fixing and stabilization in this round. There is also a bunch of packaging fixes for RPM distros (RHEL/CentOS, Fedora, and SUSE) and for systemd. We've also added a new librados-striper library from Sebastien Ponce that provides a generic striping API for applications to code to.


  • The experimental keyvaluestore-dev OSD backend had an on-disk format change that prevents existing OSD data from being upgraded. This affects developers and testers only.
  • mon-specific and osd-specific leveldb options have been removed. From this point onward users should use 'leveldb_' generic options and add the options in the appropriate sections of their configuration files. Monitors will still maintain the following monitor-specific defaults:

    leveldb_write_buffer_size = 32*1024*1024 = 33554432 // 32MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = ""

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = ""
