v0.94.3 Hammer released

This Hammer point release fixes a critical (though rare) data corruption bug that could be triggered when logs are rotated via SIGHUP. It also fixes a range of other important bugs in the OSD, monitor, RGW, RBD, and CephFS.

All v0.94.x Hammer users are strongly encouraged to upgrade.

UPGRADING

  • The pg ls-by-{pool,primary,osd} commands and pg ls now take the argument recovering instead of recovery in order to include the recovering pgs in the listed pgs.
