From 0a28e3c44b05470061f15516e1c89a84fa2e8569 Mon Sep 17 00:00:00 2001 From: David Teigland <teigland@redhat.com> Date: Thu, 1 Apr 2021 17:20:00 -0500 Subject: [PATCH] Add metadata-based autoactivation property for VG and LV The autoactivation property can be specified in lvcreate or vgcreate for new LVs/VGs, and the property can be changed by lvchange or vgchange for existing LVs/VGs. --setautoactivation y|n enables|disables autoactivation of a VG or LV. Autoactivation is enabled by default, which is consistent with past behavior. The disabled state is stored as a new flag in the VG metadata, and the absence of the flag allows autoactivation. If autoactivation is disabled for the VG, then no LVs in the VG will be autoactivated (the LV autoactivation property will have no effect.) When autoactivation is enabled for the VG, then autoactivation can be controlled on individual LVs. The state of this property can be reported for LVs/VGs using the "-o autoactivation" option in lvs/vgs commands, which will report "enabled", or "" for the disabled state. Previous versions of lvm do not recognize this property. Since autoactivation is enabled by default, the disabled setting will have no effect in older lvm versions. If the VG is modified by older lvm versions, the disabled state will also be dropped from the metadata. The autoactivation property is an alternative to using the lvm.conf auto_activation_volume_list, which is still applied to to VGs/LVs in addition to the new property. If VG or LV autoactivation is disabled either in metadata or in auto_activation_volume_list, it will not be autoactivated. An autoactivation command will silently skip activating an LV when the autoactivation property is disabled. To determine the effective autoactivation behavior for a specific LV, multiple settings would need to be checked: the VG autoactivation property, the LV autoactivation property, the auto_activation_volume_list. The "activation skip" property would also be relevant, since it applies to both normal and auto activation. --- lib/config/config_settings.h | 40 ++-- lib/format_text/flags.c | 2 + lib/metadata/lv_manip.c | 4 + lib/metadata/metadata-exported.h | 6 +- lib/metadata/metadata.h | 1 - lib/report/columns.h | 2 + lib/report/properties.c | 4 + lib/report/report.c | 17 ++ test/shell/autoactivation-metadata.sh | 335 ++++++++++++++++++++++++++++++++++ tools/args.h | 28 ++- tools/command-lines.in | 9 +- tools/lvchange.c | 32 ++++ tools/lvcreate.c | 3 + tools/vgchange.c | 31 ++++ tools/vgcreate.c | 3 + 15 files changed, 486 insertions(+), 31 deletions(-) create mode 100644 test/shell/autoactivation-metadata.sh diff --git a/lib/config/config_settings.h b/lib/config/config_settings.h index a19402d9d..3946a7129 100644 --- a/lib/config/config_settings.h +++ b/lib/config/config_settings.h @@ -1119,10 +1119,12 @@ cfg(global_event_activation_CFG, "event_activation", global_CFG_SECTION, CFG_DEF "Activate LVs based on system-generated device events.\n" "When a device appears on the system, a system-generated event runs\n" "the pvscan command to activate LVs if the new PV completes the VG.\n" - "Use auto_activation_volume_list to select which LVs should be\n" - "activated from these events (the default is all.)\n" "When event_activation is disabled, the system will generally run\n" - "a direct activation command to activate LVs in complete VGs.\n") + "a direct activation command to activate LVs in complete VGs.\n" + "Activation commands that are run by the system, either from events\n" + "or at fixed points during startup, use autoactivation (-aay).
