34           [    --version ]
35

OPTIONS

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

VARIABLES

104       PV
105              Physical Volume name, a device path under  /dev.   For  commands
106              managing physical extents, a PV positional arg generally accepts
107              a suffix indicating a range (or  multiple  ranges)  of  physical
108              extents  (PEs). When the first PE is omitted, it defaults to the
109              start of the device, and when the last PE is omitted it defaults
110              to  end.   Start and end range (inclusive): PV[:PE-PE]...  Start
111              and length range (counting from 0): PV[:PE+PE]...
112
113       String
114              See the option description for information about the string con‐
115              tent.
116
117       Size[UNIT]
118              Size  is  an  input number that accepts an optional unit.  Input
119              units are always treated as base two values, regardless of capi‐
120              talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
121              input unit is specified by letter, followed by |UNIT.  UNIT rep‐
122              resents  other  possible  input units: bBsSkKmMgGtTpPeE.  b|B is
123              bytes, s|S is sectors of 512 bytes, k|K  is  kilobytes,  m|M  is
124              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
125              e|E is exabytes.  (This should not be confused with  the  output
126              control --units, where capital letters mean multiple of 1000.)
127

ENVIRONMENT VARIABLES

129       See  lvm(8)  for  information  about environment variables used by lvm.
130       For example, LVM_VG_NAME can generally be substituted for a required VG
131       parameter.
132

EXAMPLES

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