--cacheScan all devices and send the metadata to lvmetad.
--commandprofile StringThe command profile to use for command configuration. See lvm.conf(5) for more information about profiles.
--config StringConfig settings for the command. These override lvm.conf settings. 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.
-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|nIf set to no, the command will not attempt to use device-mapper. For testing and debugging.
-h|--helpDisplay help text.
--ignorelockingfailureAllows a command to continue with read-only metadata operations after locking failures.
--lockopt StringUsed to pass options for special cases to lvmlockd. See lvmlockd(8) for more information.
--longhelpDisplay long help text.
--mknodesAlso checks the LVM special files in /dev that are needed for active LVs and creates any missing ones and removes unused ones.
--notifydbusSend a notification to D-Bus. The command will exit with an error if LVM is not built with support for D-Bus notification, or if the notify_dbus config setting is disabled.
--profile StringAn alias for --commandprofile or --metadataprofile, depending on the command.
-q|--quiet ...Suppress output and log messages. Overrides --debug and --verbose. Repeat once to also suppress any prompts with answer 'no'.
--reportformat basic|jsonOverrides 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.
-t|--testRun 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 unusual 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 detail of messages sent to stdout and stderr.
--versionDisplay version information.
-y|--yesDo not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For automatic no, see -qq.)
StringSee the option description for information about the string content.
Size[UNIT]Size is an input number that accepts an optional unit. Input units are always treated as base two values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024. The default input unit is specified by letter, followed by |UNIT. UNIT represents 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.)lvm(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter. lvm(8) lvm.conf(5) lvmconfig(8)
