See \fBlvm.conf\fP(5) for more information about profiles. .ad b .HP .ad l \fB\-\-config\fP \fIString\fP .br Config 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 \fBlvm.conf\fP(5) for more information about config. .ad b .HP .ad l \fB\-d\fP|\fB\-\-debug\fP ... .br 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). .ad b .HP .ad l \fB\-\-driverloaded\fP \fBy\fP|\fBn\fP .br If set to no, the command will not attempt to use device-mapper. For testing and debugging. .ad b .HP .ad l \fB\-h\fP|\fB\-\-help\fP .br Display help text. .ad b .HP .ad l \fB\-\-labelsector\fP \fINumber\fP .br 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 LABEL_SCAN_SECTORS in the source). Use with care. .ad b .HP .ad l \fB\-\-lockopt\fP \fIString\fP .br Used to pass options for special cases to lvmlockd. See \fBlvmlockd\fP(8) for more information. .ad b .HP .ad l \fB\-\-longhelp\fP .br Display long help text. .ad b .HP .ad l \fB\-\-nolocking\fP .br Disable locking. .ad b .HP .ad l \fB\-\-profile\fP \fIString\fP .br An alias for \-\-commandprofile or \-\-metadataprofile, depending on the command. .ad b .HP .ad l \fB\-q\fP|\fB\-\-quiet\fP ... .br Suppress output and log messages. Overrides \-\-debug and \-\-verbose. Repeat once to also suppress any prompts with answer 'no'. .ad b .HP .ad l \fB\-t\fP|\fB\-\-test\fP .br 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 unusual error messages in multi-stage operations if a tool relies on reading back metadata it believes has changed but hasn't. .ad b .HP .ad l \fB\-v\fP|\fB\-\-verbose\fP ... .br Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and stderr. .ad b .HP .ad l \fB\-\-version\fP .br Display version information. .ad b .HP .ad l \fB\-y\fP|\fB\-\-yes\fP .br Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For automatic no, see \-qq.) .ad b .SH VARIABLES .HP \fIPV\fP .br 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 extents (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): \fIPV\fP[\fB:\fP\fIPE\fP\fB\-\fP\fIPE\fP]... Start and length range (counting from 0): \fIPV\fP[\fB:\fP\fIPE\fP\fB+\fP\fIPE\fP]... .HP \fIString\fP .br See the option description for information about the string content. .HP \fISize\fP[UNIT] .br 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: \fBbBsSkKmMgGtTpPeE\fP. 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.) .SH ENVIRONMENT VARIABLES See \fBlvm\fP(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter. .SH EXAMPLES If the partition table is corrupted or lost on /dev/sda, and you suspect there was an LVM partition at approximately 100 MiB, then this area of the disk can be scanned using the \fB\-\-labelsector\fP parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800). .br .B pvck \-\-labelsector 204800 /dev/sda .SH SEE ALSO .BR lvm (8) .BR lvm.conf (5) .BR lvmconfig (8) .BR pvchange (8) .BR pvck (8) .BR pvcreate (8) .BR pvdisplay (8) .BR pvmove (8) .BR pvremove (8) .BR pvresize (8) .BR pvs (8) .BR pvscan (8) .BR vgcfgbackup (8) .BR vgcfgrestore (8) .BR vgchange (8) .BR vgck (8) .BR vgcreate (8) .BR vgconvert (8) .BR vgdisplay (8) .BR vgexport (8) .BR vgextend (8) .BR vgimport (8) .BR vgimportclone (8) .BR vgmerge (8) .BR vgmknodes (8) .BR vgreduce (8) .BR vgremove (8) .BR vgrename (8) .BR vgs (8) .BR vgscan (8) .BR vgsplit (8) .BR lvcreate (8) .BR lvchange (8) .BR lvconvert (8) .BR lvdisplay (8) .BR lvextend (8) .BR lvreduce (8) .BR lvremove (8) .BR lvrename (8) .BR lvresize (8) .BR lvs (8) .BR lvscan (8) .BR lvm-fullreport (8) .BR lvm-lvpoll (8) .BR lvm2\-activation\-generator (8) .BR blkdeactivate (8) .BR lvmdump (8) .BR dmeventd (8) .BR lvmpolld (8) .BR lvmlockd (8) .BR lvmlockctl (8) .BR cmirrord (8) .BR lvmdbusd (8) .BR lvmsystemid (7) .BR lvmreport (7) .BR lvmraid (7) .BR lvmthin (7) .BR lvmcache (7)
