NAME
       pvck - Check the consistency of physical volume(s)

SYNOPSIS
       pvck position_args
           [ option_args ]

DESCRIPTION
       pvck checks the LVM metadata for consistency on PVs.

USAGE
       pvck PV ...
           [    --labelsector Number ]
           [ COMMON_OPTIONS ]

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]
           [ -v|--verbose ]
           [ -y|--yes ]
           [    --commandprofile String ]
           [    --config String ]
           [    --driverloaded y|n ]
           [    --lockopt String ]
           [    --longhelp ]
           [    --profile String ]
           [    --version ]

OPTIONS
       --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 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|n
              If set to no, the command will not attempt to use device-mapper.  For testing and debugging.

       -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
              LABEL_SCAN_SECTORS in the source). Use with care.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       --profile String
              An 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'.

       -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
              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.

       --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.)

VARIABLES
       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
              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): PV[:PE-PE]...
              Start and length range (counting from 0): PV[:PE+PE]...

       String
              See 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.)

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.

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 --labelsector
       parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800).
       pvck --labelsector 204800 /dev/sda
