NAME

SYNOPSIS

9       lvmdiskscan
10           [ option_args ]
11

DESCRIPTION

13       lvmdiskscan  scans all SCSI, (E)IDE disks, multiple devices and a bunch
14       of other block devices in the system looking  for  LVM  PVs.  The  size
15       reported  is  the  real  device size. Define a filter in lvm.conf(5) to
16       restrict the scan to avoid a CD ROM, for example.
17
18       This command is deprecated, use pvs instead.

OPTIONS

43       --commandprofile String
44              The command profile to use for command configuration.  See
45              lvm.conf(5) for more information about profiles.
46
47       --config String
48              Config settings for the command. These override lvm.conf set‐
49              tings.  The String arg uses the same format as lvm.conf, or may
50              use section/field syntax.  See lvm.conf(5) for more information
51              about config.
52
53       -d|--debug ...
54              Set debug level. Repeat from 1 to 6 times to increase the detail
55              of messages sent to the log file and/or syslog (if configured).
56
57       --driverloaded y|n
58              If set to no, the command will not attempt to use device-mapper.
59              For testing and debugging.
60
61       -h|--help
62              Display help text.
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       -l|--lvmpartition
72              Only report PVs.
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       --readonly
84              Run the command in a special read-only mode which will read on-
85              disk metadata without needing to take any locks. This can be
86              used to peek inside metadata used by a virtual machine image
87              while the virtual machine is running.  It can also be used to
88              peek inside the metadata of clustered VGs when clustered locking
89              is not configured or running. No attempt will be made to commu‐
90              nicate with the device-mapper kernel driver, so this option is
91              unable to report whether or not LVs are actually in use.
92
93       -t|--test
94              Run in test mode. Commands will not update metadata.  This is
95              implemented by disabling all metadata writing but nevertheless
96              returning success to the calling function. This may lead to
97              unusual error messages in multi-stage operations if a tool
98              relies on reading back metadata it believes has changed but
99              hasn't.
100
101       -v|--verbose ...
102              Set verbose level. Repeat from 1 to 4 times to increase the
103              detail of messages sent to stdout and stderr.
104
105       --version
106              Display version information.
107
108       -y|--yes
109              Do not prompt for confirmation interactively but always assume
110              the answer yes. Use with extreme caution.  (For automatic no,
111              see -qq.)

VARIABLES

114       String
115              See the option description for information about the string con‐
116              tent.
117
118       Size[UNIT]
119              Size is an input number that accepts an  optional  unit.   Input
120              units are always treated as base two values, regardless of capi‐
121              talization, e.g. 'k' and 'K' both refer to  1024.   The  default
122              input unit is specified by letter, followed by |UNIT.  UNIT rep‐
123              resents other possible input units:  bBsSkKmMgGtTpPeE.   b|B  is
124              bytes,  s|S  is  sectors  of 512 bytes, k|K is kilobytes, m|M is
125              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
126              e|E  is  exabytes.  (This should not be confused with the output
127              control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES

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