v0.67.8 Dumpling released
// Ceph
This Dumpling point release fixes several non-critical issues since v0.67.7. The most notable bug fixes are an auth fix in librbd (observed as an occasional crash from KVM), an improvement in the network failure detection with the monitor, and several hard to hit OSD crashes or hangs.
We recommend that all users upgrade at their convenience.
UPGRADING
- The 'rbd ls' function now returns success and returns an empty when a pool does not store any rbd images. Previously it would return an ENOENT error.
- Ceph will now issue a health warning if the 'mon osd down out interval' config option is set to zero. This warning can be disabled by adding 'mon warn on osd down out interval zero = false' to ceph.conf.
