v0.80.6 Firefly released

Sage Weil

2014-10-02 00:56:12 UTC

This is a major bugfix release for firefly, fixing a range of issues
in the OSD and monitor, particularly with cache tiering. There are
also important fixes in librados, with the watch/notify mechanism used
by librbd, and in radosgw.

A few pieces of new functionality of been backported, including improved
'ceph df' output (view amount of writeable space per pool), support for
non-default cluster names when using sysvinit or systemd, and improved
(and fixed) support for dmcrypt.

We recommend that all v0.80.x Firefly users upgrade to this release.
