11
13 vgrename renames a VG.
14
15 All VGs visible to a system need to have different names, otherwise
16 many LVM commands will refuse to run or give warning messages. VGs with
17 the same name can occur when disks are moved between machines, or fil‐
18 ters are changed. If a newly connected disk has a VG with the same name
19 as the VG containing the root filesystem, the machine may not boot cor‐
20 rectly. When two VGs have the same name, the VG UUID can be used in
21 place of the source VG name.
22
24 Rename a VG.
25
26 vgrename VG VG_new
27 [ COMMON_OPTIONS ]
28
29 Rename a VG by specifying the VG UUID.

31 vgrename String VG_new

34 Common options for command:
35 [ -A|--autobackup y|n ]
36 [ -f|--force ]
37 [ --reportformat basic|json ]
38
39 Common options for lvm:
40 [ -d|--debug ]
41 [ -h|--help ]
42 [ -q|--quiet ]
43 [ -t|--test ]
44 [ -v|--verbose ]
45 [ -y|--yes ]
46 [ --commandprofile String ]
47 [ --config String ]
48 [ --driverloaded y|n ]
49 [ --lockopt String ]
50 [ --longhelp ]
51 [ --nolocking ]
52 [ --profile String ]
53 [ --version ]
54
56 -A|--autobackup y|n
57 Specifies if metadata should be backed up automatically after a
58 change. Enabling this is strongly advised! See vgcfgbackup(8)
59 for more information.
60
61 --commandprofile String
62 The command profile to use for command configuration. See
63 lvm.conf(5) for more information about profiles.
64
65 --config String
66 Config settings for the command. These override lvm.conf set‐
67 tings. The String arg uses the same format as lvm.conf, or may
68 use section/field syntax. See lvm.conf(5) for more information
69 about config.
70
71 -d|--debug ...
72 Set debug level. Repeat from 1 to 6 times to increase the detail
73 of messages sent to the log file and/or syslog (if configured).
74
75 --driverloaded y|n
76 If set to no, the command will not attempt to use device-mapper.
77 For testing and debugging.
78
79 -f|--force ...
80 Override various checks, confirmations and protections. Use
81 with extreme caution.
82
83 -h|--help
84 Display help text.
85
86 --lockopt String
87 Used to pass options for special cases to lvmlockd. See lvm‐
88 lockd(8) for more information.
89
90 --longhelp
91 Display long help text.
92
93 --nolocking
94 Disable locking.
95
96 --profile String
97 An alias for --commandprofile or --metadataprofile, depending on
98 the command.
99
100 -q|--quiet ...
101 Suppress output and log messages. Overrides --debug and --ver‐
102 bose. Repeat once to also suppress any prompts with answer
103 'no'.
104
105 --reportformat basic|json
106 Overrides current output format for reports which is defined
107 globally by the report/output_format setting in lvm.conf. basic
108 is the original format with columns and rows. If there is more
109 than one report per command, each report is prefixed with the
110 report name for identification. json produces report output in
111 JSON format. See lvmreport(7) for more information.
112
113 -t|--test
114 Run in test mode. Commands will not update metadata. This is
115 implemented by disabling all metadata writing but nevertheless
116 returning success to the calling function. This may lead to un‐
117 usual error messages in multi-stage operations if a tool relies
118 on reading back metadata it believes has changed but hasn't.
119
120 -v|--verbose ...
121 Set verbose level. Repeat from 1 to 4 times to increase the de‐
122 tail of messages sent to stdout and stderr.
123
124 --version
125 Display version information.
126
127 -y|--yes
128 Do not prompt for confirmation interactively but always assume
129 the answer yes. Use with extreme caution. (For automatic no,
130 see -qq.)
131
133 VG
134 Volume Group name. See lvm(8) for valid names.
135
136 String
137 See the option description for information about the string con‐
138 tent.
139
140 Size[UNIT]
141 Size is an input number that accepts an optional unit. Input
142 units are always treated as base two values, regardless of capi‐
143 talization, e.g. 'k' and 'K' both refer to 1024. The default
144 input unit is specified by letter, followed by |UNIT. UNIT rep‐
145 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
146 bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G
147 is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This should not be
148 confused with the output control --units, where capital letters
149 mean multiple of 1000.)
150
152 See lvm(8) for information about environment variables used by lvm.
153 For example, LVM_VG_NAME can generally be substituted for a required VG
154 parameter.
155
157 Rename VG "vg02" to "myvg":
158 vgrename vg02 myvg
159
160 Rename the VG with the specified UUID to "myvg".
161 vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 myvg
