NAME

6       lvmdiskscan - List devices that may be used as physical volumes

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  re‐
15       ported  is  the real device size. Define a filter in lvm.conf(5) to re‐
16       strict the scan to avoid a CD ROM, for example.
17
18       This command is deprecated, use pvs instead.

OPTIONS

44       --commandprofile String
45              The command profile to use for command configuration.  See
46              lvm.conf(5) for more information about profiles.
47
48       --config String
49              Config settings for the command. These override lvm.conf set‐
50              tings.  The String arg uses the same format as lvm.conf, or may
51              use section/field syntax.  See lvm.conf(5) for more information
52              about config.
53
54       -d|--debug ...
55              Set debug level. Repeat from 1 to 6 times to increase the detail
56              of messages sent to the log file and/or syslog (if configured).
57
58       --driverloaded y|n
59              If set to no, the command will not attempt to use device-mapper.
60              For testing and debugging.
61
62       -h|--help
63              Display help text.
64
65       --lockopt String
66              Used to pass options for special cases to lvmlockd.  See lvm‐
67              lockd(8) for more information.
68
69       --longhelp
70              Display long help text.
71
72       -l|--lvmpartition
73              Only report PVs.
74
75       --nolocking
76              Disable locking.
77
78       --profile String
79              An alias for --commandprofile or --metadataprofile, depending on
80              the command.
81
82       -q|--quiet ...
83              Suppress output and log messages. Overrides --debug and --ver‐
84              bose.  Repeat once to also suppress any prompts with answer
85              'no'.
86
87       --readonly
88              Run the command in a special read-only mode which will read on-
89              disk metadata without needing to take any locks. This can be
90              used to peek inside metadata used by a virtual machine image
91              while the virtual machine is running. No attempt will be made to
92              communicate with the device-mapper kernel driver, so this option
93              is unable to report whether or not LVs are actually in use.
94
95       -t|--test
96              Run in test mode. Commands will not update metadata.  This is
97              implemented by disabling all metadata writing but nevertheless
98              returning success to the calling function. This may lead to un‐
99              usual error messages in multi-stage operations if a tool relies
100              on reading back metadata it believes has changed but hasn't.
101
102       -v|--verbose ...
103              Set verbose level. Repeat from 1 to 4 times to increase the de‐
104              tail of messages sent to stdout and stderr.
105
106       --version
107              Display version information.
108
109       -y|--yes
110              Do not prompt for confirmation interactively but always assume
111              the answer yes. Use with extreme caution.  (For automatic no,
112              see -qq.)

VARIABLES

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

ENVIRONMENT VARIABLES

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