libdevdctl: g++9 avoid Wdeprecated-copy g++9 now warns about having defined an assignment operator but using the default copy constructor, or vice versa. Avoid the issue in libdevdctl by just using the default assignment operator too. Reviewed by: asomers, dim Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D22887

zfsd should be able to online an L2ARC that disappears and returns Previously, this didn't work because L2ARC devices' labels don't contain pool GUIDs. Modify zfsd so that the pool GUID won't be required: lib/libdevdctl/guid.h Change INVALID_GUID from a uint64_t constant to a function that returns an invalid Guid object. Remove the void constructor. Nothing uses it, and it violates RAII. cddl/usr.sbin/zfsd/case_file.h cddl/usr.sbin/zfsd/case_file.cc Allow CaseFile::Find to match a CaseFile based on Vdev GUID alone. In CaseFile::ReEvaluate, attempt to online devices even if the newly arrived device has no pool GUID. cddl/usr.sbin/zfsd/vdev_iterator.cc Iterate through a pool's cache devices as well as its regular devices.

zfsd(8), the ZFS fault management daemon 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.
