This increases the space avail- able for LVs in the VG. Also, PVs that have gone missing and then returned, e.g. due to a tran- sient device failure, can be added back to the VG without re-initializ- ing them (see --restoremissing). If the specified PVs have not yet been initialized with pvcreate, vgex- tend will initialize them. In this case pvcreate options can be used, e.g. --labelsector, --metadatasize, --metadataignore, --pvmetadata- copies, --dataalignment, --dataalignmentoffset. USAGE vgextend VG PV ...

Enabling this is strongly advised! See vgcfgbackup(8) for more information. --commandprofile String The command profile to use for command configuration. See lvm.conf(5) for more information about profiles. --config String Config settings for the command. These override lvm.conf set- tings. The String arg uses the same format as lvm.conf, or may use section/field syntax. See lvm.conf(5) for more information about config. --dataalignment Size[k|UNIT] Align the start of a PV data area with a multiple of this num- ber. To see the location of the first Physical Extent (PE) of an existing PV, use pvs -o +pe_start. In addition, it may be shifted by an alignment offset, see --dataalignmentoffset. Also specify an appropriate PE size when creating a VG. --dataalignmentoffset Size[k|UNIT] Shift the start of the PV data area by this additional offset. -d|--debug ... Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file and/or syslog (if configured). --driverloaded y|n If set to no, the command will not attempt to use device-mapper. For testing and debugging. -f|--force ... Override various checks, confirmations and protections. Use with extreme caution. -h|--help Display help text. --labelsector Number By default the PV is labelled with an LVM2 identifier in its second sector (sector 1). This lets you use a different sector near the start of the disk (between 0 and 3 inclusive - see LA- BEL_SCAN_SECTORS in the source). Use with care. --lockopt String Used to pass options for special cases to lvmlockd. See lvm- lockd(8) for more information. --longhelp Display long help text. --metadataignore y|n Specifies the metadataignore property of a PV. If yes, metadata areas on the PV are ignored, and lvm will not store metadata in the metadata areas of the PV. If no, lvm will store metadata on the PV. --metadatasize Size[m|UNIT] The approximate amount of space used for each VG metadata area. The size may be rounded. -M|--metadatatype lvm2 Specifies the type of on-disk metadata to use. lvm2 (or just 2) is the current, standard format. lvm1 (or just 1) is no longer used. --nolocking Disable locking. --profile String An alias for --commandprofile or --metadataprofile, depending on the command. --pvmetadatacopies 0|1|2 The number of metadata areas to set aside on a PV for storing VG metadata. When 2, one copy of the VG metadata is stored at the front of the PV and a second copy is stored at the end. When 1, one copy of the VG metadata is stored at the front of the PV. When 0, no copies of the VG metadata are stored on the given PV. This may be useful in VGs containing many PVs (this places limi- tations on the ability to use vgsplit later.) -q|--quiet ... Suppress output and log messages. Overrides --debug and --ver- bose. Repeat once to also suppress any prompts with answer 'no'. --reportformat basic|json Overrides current output format for reports which is defined globally by the report/output_format setting in lvm.conf. basic is the original format with columns and rows. If there is more than one report per command, each report is prefixed with the report name for identification. json produces report output in JSON format. See lvmreport(7) for more information. --restoremissing Add a PV back into a VG after the PV was missing and then re- turned, e.g. due to a transient failure. The PV is not reini- tialized. -t|--test Run in test mode. Commands will not update metadata. This is implemented by disabling all metadata writing but nevertheless returning success to the calling function. This may lead to un- usual error messages in multi-stage operations if a tool relies on reading back metadata it believes has changed but hasn't. -v|--verbose ... Set verbose level. Repeat from 1 to 4 times to increase the de- tail of messages sent to stdout and stderr. --version Display version information. -y|--yes Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For automatic no, see -qq.) -Z|--zero y|n Controls if the first 4 sectors (2048 bytes) of the device are wiped. The default is to wipe these sectors unless either or both of --restorefile or --uuid are specified. VARIABLES VG Volume Group name. See lvm(8) for valid names. PV Physical Volume name, a device path under /dev. For commands managing physical extents, a PV positional arg generally accepts a suffix indicating a range (or multiple ranges) of physical ex- tents (PEs). When the first PE is omitted, it defaults to the start of the device, and when the last PE is omitted it defaults to end. Start and end range (inclusive): PV[:PE-PE]... Start and length range (counting from 0): PV[:PE+PE]... String See the option description for information about the string con- tent. Size[UNIT] Size is an input number that accepts an optional unit. Input units are always treated as base two values, regardless of capi- talization, e.g. 'k' and 'K' both refer to 1024. The default input unit is specified by letter, followed by |UNIT. UNIT rep- resents other possible input units: bBsSkKmMgGtTpPeE. b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes, e|E is exabytes. (This should not be confused with the output control --units, where capital letters mean multiple of 1000.) ENVIRONMENT VARIABLES See lvm(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
