Second round of ZFS improvements in FreeBSD, Postgres finds that non-FreeBSD/non-Illumos systems are corrupting data, interview with Kevin Bowling, BSDCan list of talks, and cryptographic right answers. Headlines [Other big ZFS improvements you might have missed] 9075 Improve ZFS pool import/load process and corrupted pool recovery One of the first tasks during the pool load process is to parse a config provided from userland that describes what devices the pool is composed of. A vdev tree is generated from that config, and then all the vdevs are opened. The Meta Object Set (MOS) of the pool is accessed, and several metadata objects that are necessary to load the pool are read. The exact configuration of the pool is also stored inside the MOS. Since the configuration provided from userland is external and might not accurately describe the vdev tree of the pool at the txg that is being loaded, it cannot be relied upon to safely operate the pool. For that reason, the configuration in the MOS is read ea
