Add zfsd, which deals with hard drive faults in ZFS pools. It manages hotspares and replements in drive slots that publish physical paths. cddl/usr.sbin/zfsd Add zfsd(8) and its unit tests cddl/usr.sbin/Makefile Add zfsd to the build lib/libdevdctl A C++ library that helps devd clients process events lib/Makefile share/mk/bsd.libnames.mk share/mk/src.libnames.mk Add libdevdctl to the build. It's a private library, unusable by out-of-tree software. etc/defaults/rc.conf By default, set zfsd_enable to NO etc/mtree/BSD.include.dist Add a directory for libdevdctl's include files etc/mtree/BSD.tests.dist Add a directory for zfsd's unit tests etc/mtree/BSD.var.dist Add /var/db/zfsd/cases, where zfsd stores case files while it's shut down. etc/rc.d/Makefile etc/rc.d/zfsd Add zfsd's rc script sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c Fix the resource.fs.zfs.statechange message. It had a number of problems: It was only being emitted on a transition to the HEALTHY state. That made it impossible for zfsd to take actions based on drives getting sicker. It compared the new state to vdev_prevstate, which is the state that the vdev had the last time it was opened. That doesn't make sense, because a vdev can change state multiple times without being reopened. vdev_set_state contains logic that will change the device's new state based on various conditions. However, the statechange event was being posted _before_ that logic took effect. Now it's being posted after.
