v0.90 released [feedly]



----
v0.90 released
// Ceph

This is the last development release before Christmas. There are some API cleanups for librados and librbd, and lots of bug fixes across the board for the OSD, MDS, RGW, and CRUSH. The OSD also gets support for discard (potentially helpful on SSDs, although it is off by default), and there are several improvements to ceph-disk.

The next two development releases will be getting a slew of new functionality for hammer. Stay tuned!

UPGRADING

  • Previously, the formatted output of 'ceph pg stat -f …' was a full pg dump that included all metadata about all PGs in the system. It is now a concise summary of high-level PG stats, just like the unformatted 'ceph pg stat' command.
  • All JSON dumps of floating point values were incorrecting surrounding the value with quotes. These quotes have been removed. Any consumer of structured JSON output that was consuming the floating point values was previously having to interpret the quoted string and will most likely need to be fixed to take the unquoted number.
