13 vgmerge merges two existing VGs. The inactive source VG is merged into
14 the destination VG if physical extent sizes are equal and PV and LV
15 summaries of both VGs fit into the destination VG's limits.

23 Common options for lvm:
24 [ -d|--debug ]
25 [ -h|--help ]
26 [ -q|--quiet ]
27 [ -t|--test ]
28 [ -v|--verbose ]
29 [ -y|--yes ]

34 [ --longhelp ]
35 [ --nolocking ]
36 [ --profile String ]
37 [ --version ]
38
40 -A|--autobackup y|n
41 Specifies if metadata should be backed up automatically after a
42 change. Enabling this is strongly advised! See vgcfgbackup(8)
43 for more information.
44
45 --commandprofile String
46 The command profile to use for command configuration. See
47 lvm.conf(5) for more information about profiles.
48
49 --config String
50 Config settings for the command. These override lvm.conf set‐
51 tings. The String arg uses the same format as lvm.conf, or may
52 use section/field syntax. See lvm.conf(5) for more information
53 about config.
54
55 -d|--debug ...
56 Set debug level. Repeat from 1 to 6 times to increase the detail
57 of messages sent to the log file and/or syslog (if configured).
58
59 --driverloaded y|n
60 If set to no, the command will not attempt to use device-mapper.
61 For testing and debugging.
62
63 -h|--help
64 Display help text.
65
66 -l|--list
67 Display merged destination VG like vgdisplay -v.
68
69 --lockopt String
70 Used to pass options for special cases to lvmlockd. See lvm‐
71 lockd(8) for more information.
72
73 --longhelp
74 Display long help text.
75
76 --nolocking
77 Disable locking.
78
79 --profile String
80 An alias for --commandprofile or --metadataprofile, depending on
81 the command.
82
83 -q|--quiet ...
84 Suppress output and log messages. Overrides --debug and --ver‐
85 bose. Repeat once to also suppress any prompts with answer
86 'no'.
87
88 -t|--test
89 Run in test mode. Commands will not update metadata. This is
90 implemented by disabling all metadata writing but nevertheless
91 returning success to the calling function. This may lead to un‐
92 usual error messages in multi-stage operations if a tool relies
93 on reading back metadata it believes has changed but hasn't.
94
95 -v|--verbose ...
96 Set verbose level. Repeat from 1 to 4 times to increase the de‐
97 tail of messages sent to stdout and stderr.
98
99 --version
100 Display version information.
101
102 -y|--yes
103 Do not prompt for confirmation interactively but always assume
104 the answer yes. Use with extreme caution. (For automatic no,
105 see -qq.)
106
108 VG
109 Volume Group name. See lvm(8) for valid names.
110
111 String
112 See the option description for information about the string con‐
113 tent.
114
115 Size[UNIT]
116 Size is an input number that accepts an optional unit. Input
117 units are always treated as base two values, regardless of capi‐
118 talization, e.g. 'k' and 'K' both refer to 1024. The default
119 input unit is specified by letter, followed by |UNIT. UNIT rep‐
120 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
121 bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G
122 is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This should not be
123 confused with the output control --units, where capital letters
124 mean multiple of 1000.)
125
127 See lvm(8) for information about environment variables used by lvm.
128 For example, LVM_VG_NAME can generally be substituted for a required VG
129 parameter.
130
132 Merge an inactive VG named "vg00" into the active or inactive VG named
133 "databases", giving verbose runtime information.
