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
17 directly.

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 ]

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