14 lvm lvpoll is an internal command used by lvmpolld(8) to monitor and
15 complete lvconvert(8) and pvmove(8) operations. lvpoll itself does not
16 initiate these operations and should not normally need to be run di‐
17 rectly.

25 [ COMMON_OPTIONS ]
26 Common options for lvm:
28 [ -d|--debug ]
29 [ -h|--help ]
30 [ -q|--quiet ]
31 [ -t|--test ]
32 [ -v|--verbose ]
33 [ -y|--yes ]

35 [ --config String ]
36 [ --driverloaded y|n ]
37 [ --lockopt String ]
38 [ --longhelp ]
39 [ --nolocking ]
40 [ --profile String ]
41 [ --version ]
42
44 --abort
45 Stop processing a poll operation in lvmpolld.
46 -A|--autobackup y|n
48 Specifies if metadata should be backed up automatically after a
49 change. Enabling this is strongly advised! See vgcfgbackup(8)
50 for more information.
51 --commandprofile String
53 The command profile to use for command configuration. See
54 lvm.conf(5) for more information about profiles.
55 --config String
57 Config settings for the command. These override lvm.conf set‐
58 tings. The String arg uses the same format as lvm.conf, or may
59 use section/field syntax. See lvm.conf(5) for more information
60 about config.
61 -d|--debug ...
63 Set debug level. Repeat from 1 to 6 times to increase the detail
64 of messages sent to the log file and/or syslog (if configured).
65 --driverloaded y|n
67 If set to no, the command will not attempt to use device-mapper.
68 For testing and debugging.
69 --handlemissingpvs
71 Allows a polling operation to continue when PVs are missing,
72 e.g. for repairs due to faulty devices.
73 -h|--help
75 Display help text.
76 -i|--interval Number
78 Report progress at regular intervals.
79 --lockopt String
81 Used to pass options for special cases to lvmlockd. See lvm‐
82 lockd(8) for more information.
83 --longhelp
85 Display long help text.
86 --nolocking
88 Disable locking.
89 --polloperation pvmove|convert|merge|merge_thin
91 The command to perform from lvmpolld.
92 --profile String
94 An alias for --commandprofile or --metadataprofile, depending on
95 the command.
96 -q|--quiet ...
98 Suppress output and log messages. Overrides --debug and --ver‐
99 bose. Repeat once to also suppress any prompts with answer
100 'no'.
101 -t|--test
103 Run in test mode. Commands will not update metadata. This is
104 implemented by disabling all metadata writing but nevertheless
105 returning success to the calling function. This may lead to un‐
106 usual error messages in multi-stage operations if a tool relies
107 on reading back metadata it believes has changed but hasn't.
108 -v|--verbose ...
110 Set verbose level. Repeat from 1 to 4 times to increase the de‐
111 tail of messages sent to stdout and stderr.
112 --version
114 Display version information.
115 -y|--yes
117 Do not prompt for confirmation interactively but always assume
118 the answer yes. Use with extreme caution. (For automatic no,
119 see -qq.)
120
122 LV
123 Logical Volume name. See lvm(8) for valid names. An LV posi‐
124 tional arg generally includes the VG name and LV name, e.g.
125 VG/LV.
126 String
128 See the option description for information about the string con‐
129 tent.
130 Size[UNIT]
132 Size is an input number that accepts an optional unit. Input
133 units are always treated as base two values, regardless of capi‐
134 talization, e.g. 'k' and 'K' both refer to 1024. The default
135 input unit is specified by letter, followed by |UNIT. UNIT rep‐
136 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
137 bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G
138 is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This should not be
139 confused with the output control --units, where capital letters
140 mean multiple of 1000.)
141
143 See lvm(8) for information about environment variables used by lvm.
144 For example, LVM_VG_NAME can generally be substituted for a required VG
145 parameter.
146
148 To find the name of the pvmove LV that was created by an original pv‐
149 move /dev/name command, use the command:
150 lvs -a -S move_pv=/dev/name.
151
153 Continue polling a pvmove operation.
154 lvm lvpoll --polloperation pvmove vg00/pvmove0
155 Abort a pvmove operation.
157 lvm lvpoll --polloperation pvmove --abort vg00/pvmove0
158 Continue polling a mirror conversion.
160 lvm lvpoll --polloperation convert vg00/lvmirror
161 Continue mirror repair.
163 lvm lvpoll --polloperation convert vg/damaged_mirror --handlemissingpvs
164 Continue snapshot merge.
166 lvm lvpoll --polloperation merge vg/snapshot_old
167 Continue thin snapshot merge.
169 lvm lvpoll --polloperation merge_thin vg/thin_snapshot
