32           [    --profile String ]
33           [    --version ]
34

OPTIONS

36       --commandprofile String
37              The command profile to use for command configuration.  See
38              lvm.conf(5) for more information about profiles.
39
40       --config String
41              Config settings for the command. These override lvm.conf set‐
42              tings.  The String arg uses the same format as lvm.conf, or may
43              use section/field syntax.  See lvm.conf(5) for more information
44              about config.
45
46       -d|--debug ...
47              Set debug level. Repeat from 1 to 6 times to increase the detail
48              of messages sent to the log file and/or syslog (if configured).
49
50       --driverloaded y|n
51              If set to no, the command will not attempt to use device-mapper.
52              For testing and debugging.
53
54       -h|--help
55              Display help text.
56
57       --labelsector Number
58              By default the PV is labelled with an LVM2 identifier in its
59              second sector (sector 1). This lets you use a different sector
60              near the start of the disk (between 0 and 3 inclusive - see
61              LABEL_SCAN_SECTORS in the source). Use with care.
62
63       --lockopt String
64              Used to pass options for special cases to lvmlockd.  See lvm‐
65              lockd(8) for more information.
66
67       --longhelp
68              Display long help text.
69
70       --profile String
71              An alias for --commandprofile or --metadataprofile, depending on
72              the command.
73
74       -q|--quiet ...
75              Suppress output and log messages. Overrides --debug and --ver‐
76              bose.  Repeat once to also suppress any prompts with answer
77              'no'.
78
79       -t|--test
80              Run in test mode. Commands will not update metadata.  This is
81              implemented by disabling all metadata writing but nevertheless
82              returning success to the calling function. This may lead to
83              unusual error messages in multi-stage operations if a tool
84              relies on reading back metadata it believes has changed but
85              hasn't.
86
87       -v|--verbose ...
88              Set verbose level. Repeat from 1 to 4 times to increase the
89              detail of messages sent to stdout and stderr.
90
91       --version
92              Display version information.
93
94       -y|--yes
95              Do not prompt for confirmation interactively but always assume
96              the answer yes. Use with extreme caution.  (For automatic no,
97              see -qq.)

VARIABLES

100       PV
101              Physical Volume name, a device path under  /dev.   For  commands
102              managing physical extents, a PV positional arg generally accepts
103              a suffix indicating a range (or  multiple  ranges)  of  physical
104              extents  (PEs). When the first PE is omitted, it defaults to the
105              start of the device, and when the last PE is omitted it defaults
106              to  end.   Start and end range (inclusive): PV[:PE-PE]...  Start
107              and length range (counting from 0): PV[:PE+PE]...
108
109       String
110              See the option description for information about the string con‐
111              tent.
112
113       Size[UNIT]
114              Size  is  an  input number that accepts an optional unit.  Input
115              units are always treated as base two values, regardless of capi‐
116              talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
117              input unit is specified by letter, followed by |UNIT.  UNIT rep‐
118              resents  other  possible  input units: bBsSkKmMgGtTpPeE.  b|B is
119              bytes, s|S is sectors of 512 bytes, k|K  is  kilobytes,  m|M  is
120              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
121              e|E is exabytes.  (This should not be confused with  the  output
122              control --units, where capital letters mean multiple of 1000.)
123

ENVIRONMENT VARIABLES

125       See  lvm(8)  for  information  about environment variables used by lvm.
126       For example, LVM_VG_NAME can generally be substituted for a required VG
127       parameter.
128

EXAMPLES

130       If  the  partition table is corrupted or lost on /dev/sda, and you sus‐
131       pect there was an LVM partition at approximately  100  MiB,  then  this
132       area  of the disk can be scanned using the --labelsector parameter with
133       a value of 204800 (100 * 1024 * 1024 / 512 = 204800).
134       pvck --labelsector 204800 /dev/sda
