Remove explicit double quotes from columns.h 'id' entries. The 'id' entries in columns.h are the report field names. Since these are unique, we'd like to use them in generation of 'get' / 'set' functions. As a step towards using them for this purpose, remove the explicit double quotes and use the macro '#' character to add the double quotes back when placing them into the '_fields' array 'id' member.

Add lv_layout_and_type fn, lv_layout and lv_type reporting fields. The lv_layout and lv_type fields together help with LV identification. We can do basic identification using the lv_attr field which provides very condensed view. In contrast to that, the new lv_layout and lv_type fields provide more detialed information on exact layout and type used for LVs. For top-level LVs which are pure types not combined with any other LV types, the lv_layout value is equal to lv_type value. For non-top-level LVs which may be combined with other types, the lv_layout describes the underlying layout used, while the lv_type describes the use/type/usage of the LV. These two new fields are both string lists so selection (-S/--select) criteria can be defined using the list operators easily: [] for strict matching {} for subset matching. For example, let's consider this: $ lvs -a -o name,vg_name,lv_attr,layout,type LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare pool vg twi-a-tz-- pool,thin pool,thin [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tdata_rimage_0] vg iwi-aor--- linear image,raid [pool_tdata_rimage_1] vg iwi-aor--- linear image,raid [pool_tdata_rimage_2] vg iwi-aor--- linear image,raid [pool_tdata_rimage_3] vg iwi-aor--- linear image,raid [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rimage_0] vg iwi-aor--- linear image,raid [pool_tmeta_rimage_1] vg iwi-aor--- linear image,raid [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin thin_vol1 vg Vwi-a-tz-- thin thin thin_vol2 vg Vwi-a-tz-- thin multiple,origin,thin Which is a situation with thin pool, thin volumes and thin snapshots. We can see internal 'pool_tdata' volume that makes up thin pool has actually a level10 raid layout and the internal 'pool_tmeta' has level1 raid layout. Also, we can see that 'thin_snap1' and 'thin_snap2' are both thin snapshots while 'thin_vol1' is thin origin (having multiple snapshots). Such reporting scheme provides much better base for selection criteria in addition to providing more detailed information, for example: $ lvs -a -o name,vg_name,lv_attr,layout,type -S 'type=metadata' LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid (selected all LVs which are related to metadata of any type) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={metadata,thin}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs which hold metadata related to thin) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={thin,snapshot}' LV VG Attr Layout Type thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin (selected all LVs which are thin snapshots) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout=raid' LV VG Attr Layout Type [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid layout, any raid layout) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout={raid,level1}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid level1 layout exactly) And so on...

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.

report: fix pe_start column type from NUM to SIZ The 'pe_start' column was incorrectly marked as being of type NUM. This was not correct as pe_start is actually of type SIZ, which means it can have a size suffix and hence it's not a pure numeric value. Proper column type is important for selection to work correctly, so we can also do comparisons while using suffixes. This is also important for new "json_std" output format which does not put double quotes around pure numeric values. With pe_start incorrectly marked as NUM instead of SIZ, this produced invalid JSON output like '"pe_start" = 1.00m' because it contained the 'm' (or other) size suffix. If properly marked as SIZ, this is then put in double quotes like '"pe_start" = "1.00m"'.

device usage based on devices file The LVM devices file lists devices that lvm can use. The default file is /etc/lvm/devices/system.devices, and the lvmdevices(8) command is used to add or remove device entries. If the file does not exist, or if lvm.conf includes use_devicesfile=0, then lvm will not use a devices file. When the devices file is in use, the regex filter is not used, and the filter settings in lvm.conf or on the command line are ignored. LVM records devices in the devices file using hardware-specific IDs, such as the WWID, and attempts to use subsystem-specific IDs for virtual device types. These device IDs are also written in the VG metadata. When no hardware or virtual ID is available, lvm falls back using the unstable device name as the device ID. When devnames are used, lvm performs extra scanning to find devices if their devname changes, e.g. after reboot. When proper device IDs are used, an lvm command will not look at devices outside the devices file, but when devnames are used as a fallback, lvm will scan devices outside the devices file to locate PVs on renamed devices. A config setting search_for_devnames can be used to control the scanning for renamed devname entries. Related to the devices file, the new command option --devices <devnames> allows a list of devices to be specified for the command to use, overriding the devices file. The listed devices act as a sort of devices file in terms of limiting which devices lvm will see and use. Devices that are not listed will appear to be missing to the lvm command. Multiple devices files can be kept in /etc/lvm/devices, which allows lvm to be used with different sets of devices, e.g. system devices do not need to be exposed to a specific application, and the application can use lvm on its own set of devices that are not exposed to the system. The option --devicesfile <filename> is used to select the devices file to use with the command. Without the option set, the default system devices file is used. Setting --devicesfile "" causes lvm to not use a devices file. An existing, empty devices file means lvm will see no devices. The new command vgimportdevices adds PVs from a VG to the devices file and updates the VG metadata to include the device IDs. vgimportdevices -a will import all VGs into the system devices file. LVM commands run by dmeventd not use a devices file by default, and will look at all devices on the system. A devices file can be created for dmeventd (/etc/lvm/devices/dmeventd.devices) If this file exists, lvm commands run by dmeventd will use it. Internal implementaion: - device_ids_read - read the devices file . add struct dev_use (du) to cmd->use_devices for each devices file entry - dev_cache_scan - get /dev entries . add struct device (dev) to dev_cache for each device on the system - device_ids_match - match devices file entries to /dev entries . match each du on cmd->use_devices to a dev in dev_cache, using device ID . on match, set du->dev, dev->id, dev->flags MATCHED_USE_ID - label_scan - read lvm headers and metadata from devices . filters are applied, those that do not need data from the device . filter-deviceid skips devs without MATCHED_USE_ID, i.e. skips /dev entries that are not listed in the devices file . read lvm label from dev . filters are applied, those that use data from the device . read lvm metadata from dev . add info/vginfo structs for PVs/VGs (info is "lvmcache") - device_ids_find_renamed_devs - handle devices with unstable devname ID where devname changed . this step only needed when devs do not have proper device IDs, and their dev names change, e.g. after reboot sdb becomes sdc. . detect incorrect match because PVID in the devices file entry does not match the PVID found when the device was read above . undo incorrect match between du and dev above . search system devices for new location of PVID . update devices file with new devnames for PVIDs on renamed devices . label_scan the renamed devs - continue with command processing

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.
