10 [ option_args ]
11
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 This command is deprecated, use pvs instead.

24 [ COMMON_OPTIONS ]
25 Common options for lvm:
27 [ -d|--debug ]
28 [ -h|--help ]
29 [ -q|--quiet ]
30 [ -t|--test ]
31 [ -v|--verbose ]
32 [ -y|--yes ]
33 [ --commandprofile String ]
34 [ --config String ]
35 [ --devices PV ]
36 [ --devicesfile String ]
37 [ --driverloaded y|n ]
38 [ --journal String ]
39 [ --lockopt String ]
40 [ --longhelp ]
41 [ --nohints ]
42 [ --nolocking ]
43 [ --profile String ]
44 [ --version ]
45
47 --commandprofile String
48 The command profile to use for command configuration. See
49 lvm.conf(5) for more information about profiles.
50 --config String
52 Config settings for the command. These override lvm.conf(5) set‐
53 tings. The String arg uses the same format as lvm.conf(5), or
54 may use section/field syntax. See lvm.conf(5) for more informa‐
55 tion about config.
56 -d|--debug ...
58 Set debug level. Repeat from 1 to 6 times to increase the detail
59 of messages sent to the log file and/or syslog (if configured).
60 --devices PV
62 Restricts the devices that are visible and accessible to the
63 command. Devices not listed will appear to be missing. This op‐
64 tion can be repeated, or accepts a comma separated list of de‐
65 vices. This overrides the devices file.
66 --devicesfile String
68 A file listing devices that LVM should use. The file must exist
69 in /etc/lvm/devices/ and is managed with the lvmdevices(8) com‐
70 mand. This overrides the lvm.conf(5) devices/devicesfile and
71 devices/use_devicesfile settings.
72 --driverloaded y|n
74 If set to no, the command will not attempt to use device-mapper.
75 For testing and debugging.
76 -h|--help
78 Display help text.
79 --journal String
81 Record information in the systemd journal. This information is
82 in addition to information enabled by the lvm.conf log/journal
83 setting. command: record information about the command. out‐
84 put: record the default command output. debug: record full com‐
85 mand debugging.
86 --lockopt String
88 Used to pass options for special cases to lvmlockd. See lvm‐
89 lockd(8) for more information.
90 --longhelp
92 Display long help text.
93 -l|--lvmpartition
95 Only report PVs.
96 --nohints
98 Do not use the hints file to locate devices for PVs. A command
99 may read more devices to find PVs when hints are not used. The
100 command will still perform standard hint file invalidation where
101 appropriate.
102 --nolocking
104 Disable locking. Use with caution, concurrent commands may pro‐
105 duce incorrect results.
106 --profile String
108 An alias for --commandprofile or --metadataprofile, depending on
109 the command.
110 -q|--quiet ...
112 Suppress output and log messages. Overrides --debug and --ver‐
113 bose. Repeat once to also suppress any prompts with answer
114 'no'.
115 --readonly
117 Run the command in a special read-only mode which will read on-
118 disk metadata without needing to take any locks. This can be
119 used to peek inside metadata used by a virtual machine image
120 while the virtual machine is running. No attempt will be made to
121 communicate with the device-mapper kernel driver, so this option
122 is unable to report whether or not LVs are actually in use.
123 -t|--test
125 Run in test mode. Commands will not update metadata. This is
126 implemented by disabling all metadata writing but nevertheless
127 returning success to the calling function. This may lead to un‐
128 usual error messages in multi-stage operations if a tool relies
129 on reading back metadata it believes has changed but hasn't.
130 -v|--verbose ...
132 Set verbose level. Repeat from 1 to 4 times to increase the de‐
133 tail of messages sent to stdout and stderr.
134 --version
136 Display version information.
137 -y|--yes
139 Do not prompt for confirmation interactively but always assume
140 the answer yes. Use with extreme caution. (For automatic no,
141 see -qq.)
142
144 String See the option description for information about the string con‐
145 tent.
146 Size[UNIT]
148 Size is an input number that accepts an optional unit. Input
149 units are always treated as base two values, regardless of capi‐
150 talization, e.g. 'k' and 'K' both refer to 1024. The default
151 input unit is specified by letter, followed by |UNIT. UNIT rep‐
152 resents other possible input units: b|B is bytes, s|S is sectors
153 of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB,
154 p|P is PiB, e|E is EiB. (This should not be confused with the
155 output control --units, where capital letters mean multiple of
156 1000.)
157
159 See lvm(8) for information about environment variables used by lvm.
160 For example, LVM_VG_NAME can generally be substituted for a required VG
161 parameter.
