From 9a2648de67a94422ec4e7123c9c3428eeb1b3b4e Mon Sep 17 00:00:00 2001 From: mav Date: Fri, 13 Nov 2015 09:08:59 +0000 Subject: [PATCH] MFC r287745: 5997 FRU field not set during pool creation and never updated ZFS already supports storing the vdev FRU in a vdev property. There is code in libzfs to work with this property, and there is code in the zfs-retire FMA module that looks for that information. But there is no code actually setting or updating the FRU. To address this, ZFS is changed to send a handful of new events whenever a vdev is added, attached, cleared, or onlined, as well as when a pool is created or imported. Note that syseventd is not currently available on FreeBSD and thus some work is needed to actually support the new ZFS events (e.g. in zfsd) to actually use this capability, this changeset is mostly a diff reduction from upstream. illumos/illumos-gate@1437283407f89cab03860accf49408f94559bc34 Illumos issues: 5997 FRU field not set during pool creation and never updated https://www.illumos.org/issues/5997 git-svn-id: svn://svn.freebsd.org/base/stable/10@290745 ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f --- .../opensolaris/uts/common/fs/zfs/spa.c | 18 +++++++++++++----- .../opensolaris/uts/common/fs/zfs/vdev.c | 9 +++++++++ .../uts/common/sys/sysevent/eventdefs.h | 7 ++++++- 3 files changed, 28 insertions(+), 6 deletions(-) diff --git a/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c b/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c index b57eb958b..a395111af 100644 --- a/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c +++ b/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c @@ -22,7 +22,7 @@ /* * Copyright (c) 2005, 2010, Oracle and/or its affiliates.
