These are components of normal LVs, such as mirrors, which are not independently accessible, e.g. not mountable. . .TP .O_binary Use binary values "0" or "1" instead of descriptive literal values for columns that have exactly two valid values to report (not counting the "unknown" value which denotes that the value could not be determined). . .TP .O_commandprofile The command profile to use for command configuration. See \fBlvm.conf\fP(5) for more information about profiles. . .TP .O_config Config settings for the command. These override \fBlvm.conf\fP(5) settings. The String arg uses the same format as \fBlvm.conf\fP(5), or may use section/field syntax. See \fBlvm.conf\fP(5) for more information about config. . .TP .O_configreport See \fBlvmreport\fP(7). . .TP .O_debug Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file and/or syslog (if configured). . .TP .O_devices Restricts the devices that are visible and accessible to the command. Devices not listed will appear to be missing. This option can be repeated, or accepts a comma separated list of devices. This overrides the devices file. . .TP .O_devicesfile A file listing devices that LVM should use. The file must exist in \fI/etc/lvm/devices/\fP and is managed with the \fBlvmdevices\fP(8) command. This overrides the \fBlvm.conf\fP(5) \fBdevices/devicesfile\fP and \fBdevices/use_devicesfile\fP settings. . .TP .O_driverloaded If set to no, the command will not attempt to use device-mapper. For testing and debugging. . .TP .O_foreign Report/display foreign VGs that would otherwise be skipped. See \fBlvmsystemid\fP(7) for more information about foreign VGs. . .TP .O_headings Type of headings to use in report output. \fBnone\fP or \fB0\fP: No headings. \fBabbrev\fP or \fB1\fP: Column name abbreviations. \fBfull\fP or \fB2\fP: Full column names. . .TP .O_help Display help text. . .TP .O_history Include historical LVs in the output. (This has no effect unless LVs were removed while \fBlvm.conf\fP(5) \fBmetadata/record_lvs_history\fP was enabled. . .TP .O_ignorelockingfailure Allows a command to continue with read-only metadata operations after locking failures. . .TP .O_journal Record information in the systemd journal. This information is in addition to information enabled by the lvm.conf log/journal setting. command: record information about the command. output: record the default command output. debug: record full command debugging. . .TP .O_lockopt Used to pass options for special cases to lvmlockd. See \fBlvmlockd\fP(8) for more information. . .TP .O_logonly Suppress command report and display only log report. . .TP .O_longhelp Display long help text. . .TP .O_nameprefixes Add an "LVM2_" prefix plus the field name to the output. Useful with \-\-noheadings to produce a list of field=value pairs that can be used to set environment variables (for example, in udev rules). . .TP .O_noheadings Suppress the headings line that is normally the first line of output. Useful if grepping the output. . .TP .O_nohints Do not use the hints file to locate devices for PVs. A command may read more devices to find PVs when hints are not used. The command will still perform standard hint file invalidation where appropriate. . .TP .O_nolocking Disable locking. Use with caution, concurrent commands may produce incorrect results. . .TP .O_nosuffix Suppress the suffix on output sizes. Use with \-\-units (except h and H) if processing the output. . .TP .O_options Comma-separated, ordered list of fields to display in columns. String arg syntax is: [\fB+\fP|\fB\-\fP|\fB#\fP]\fIField1\fP[\fB,\fP\fIField2\fP ...] The prefix \fB+\fP will append the specified fields to the default fields, \fB\-\fP will remove the specified fields from the default fields, and \fB#\fP will compact specified fields (removing them when empty for all rows.) Use \fB\-o help\fP to view the list of all available fields. Use separate lists of fields to add, remove or compact by repeating the \-o option: \-o+field1,field2 \-o\-field3,field4 \-o#field5. These lists are evaluated from left to right. Use field name \fBlv_all\fP to view all LV fields, \fBvg_all\fP all VG fields, \fBpv_all\fP all PV fields, \fBpvseg_all\fP all PV segment fields, \fBseg_all\fP all LV segment fields, and \fBpvseg_all\fP all PV segment columns. See the \fBlvm.conf\fP(5) report section for more config options. See \fBlvmreport\fP(7) for more information about reporting. . .TP .O_profile An alias for \-\-commandprofile or \-\-metadataprofile, depending on the command. . .TP .O_quiet Suppress output and log messages. Overrides \-\-debug and \-\-verbose. Repeat once to also suppress any prompts with answer 'no'. . .TP .O_readonly Prevent the command from making changes, including activation and metadata updates. (See \-\-permission r for read only LVs.) . .TP .O_reportformat Overrides current output format for reports which is defined globally by the report/output_format setting in \fBlvm.conf\fP(5). \fBbasic\fP is the original format with columns and rows. If there is more than one report per command, each report is prefixed with the report name for identification. \fBjson\fP produces report output in JSON format. \fBjson_std\fP produces report output in JSON format which is more compliant with JSON standard. See \fBlvmreport\fP(7) for more information. . .TP .O_rows Output columns as rows. . .TP .O_segments Use default columns that emphasize segment information. . .TP .O_select Select objects for processing and reporting based on specified criteria. The criteria syntax is described by \fB\-\-select help\fP and \fBlvmreport\fP(7). For reporting commands, one row is displayed for each object matching the criteria. See \fB\-\-options help\fP for selectable object fields. Rows can be displayed with an additional "selected" field (\-o selected) showing 1 if the row matches the selection and 0 otherwise. For non-reporting commands which process LVM entities, the selection is used to choose items to process. . .TP .O_separator String to use to separate each column. Useful if grepping the output. . .TP .O_shared Report/display shared VGs that would otherwise be skipped when lvmlockd is not being used on the host. See \fBlvmlockd\fP(8) for more information about shared VGs. . .TP .O_sort Comma-separated ordered list of columns to sort by. Replaces the default selection. Precede any column with \fB\-\fP for a reverse sort on that column. . .TP .O_test Run in test mode. Commands will not update metadata. This is implemented by disabling all metadata writing but nevertheless returning success to the calling function. This may lead to unusual error messages in multi-stage operations if a tool relies on reading back metadata it believes has changed but hasn't. . .TP .O_unbuffered Produce output immediately without sorting or aligning the columns properly. . .TP .O_units All sizes are output in these units: human-(r)eadable with '<' rounding indicator, (h)uman-readable, (b)ytes, (s)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Custom units can be specified, e.g. \-\-units 3M. . .TP .O_unquoted When used with \-\-nameprefixes, output values in the field=value pairs are not quoted. . .TP .O_verbose Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and stderr. . .TP .O_version Display version information. . .TP .O_yes Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For automatic no, see \-qq.) . .SH VARIABLES . .TP .I VG Volume Group name. See \fBlvm\fP(8) for valid names. . .TP .I LV Logical Volume name. See \fBlvm\fP(8) for valid names. An LV positional arg generally includes the VG name and LV name, e.g. VG/LV. . .TP .I Tag Tag name. See \fBlvm\fP(8) for information about tag names and using tags in place of a VG, LV or PV. . .TP .I String See the option description for information about the string content. . .TP .IR Size [UNIT] Size is an input number that accepts an optional unit. Input units are always treated as base two values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024. The default input unit is specified by letter, followed by |UNIT. UNIT represents other possible input units: .BR b | B is bytes, .BR s | S is sectors of 512 bytes, .BR k | K is KiB, .BR m | M is MiB, .BR g | G is GiB, .BR t | T is TiB, .BR p | P is PiB, .BR e | E is EiB. (This should not be confused with the output control \-\-units, where capital letters mean multiple of 1000.) . .SH ENVIRONMENT VARIABLES . See \fBlvm\fP(8) for information about environment variables used by lvm. For example, \fBLVM_VG_NAME\fP can generally be substituted for a required VG parameter. . .SH NOTES . The lv_attr bits are: . .IP 1 3 Volume type: (\fBC\fP)ache, (\fBm\fP)irrored, (\fBM\fP)irrored without initial sync, (\fBo\fP)rigin, (\fBO\fP)rigin with merging snapshot, inte(\fBg\fP)rity, (\fBr\fP)aid, (\fBR\fP)aid without initial sync, (\fBs\fP)napshot, merging (\fBS\fP)napshot, (\fBp\fP)vmove, (\fBv\fP)irtual, mirror or raid (\fBi\fP)mage, mirror or raid (\fBI\fP)mage out-of\-sync, mirror (\fBl\fP)og device, under (\fBc\fP)onversion, thin (\fBV\fP)olume, (\fBt\fP)hin pool, (\fBT\fP)hin pool data, v(\fBd\fP)o pool, v(\fBD\fP)o pool data, raid or pool m(\fBe\fP)tadata or pool metadata spare. . .IP 2 Permissions: (\fBw\fP)riteable, (\fBr\fP)ead-only, (\fBR\fP)ead-only activation of non-read\-only volume . .IP 3 Allocation policy: (\fBa\fP)nywhere, (\fBc\fP)ontiguous, (\fBi\fP)nherited, c(\fBl\fP)ing, (\fBn\fP)ormal This is capitalised if the volume is currently locked against allocation changes, for example during .BR pvmove (8). . .IP 4 fixed (\fBm\fP)inor . .IP 5 State: (\fBa\fP)ctive, (\fBh\fP)istorical, (\fBs\fP)uspended, (\fBI\fP)nvalid snapshot, invalid (\fBS\fP)uspended snapshot, snapshot (\fBm\fP)erge failed, suspended snapshot (\fBM\fP)erge failed, mapped (\fBd\fP)evice present without tables, mapped device present with (\fBi\fP)nactive table, thin\-pool (\fBc\fP)heck needed, suspended thin\-pool (\fBC\fP)heck needed, (\fBX\fP) unknown . .IP 6 device (\fBo\fP)pen, (\fBX\fP) unknown . .IP 7 Target type: (\fBC\fP)ache, (\fBm\fP)irror, (\fBr\fP)aid, (\fBs\fP)napshot, (\fBt\fP)hin, (\fBu\fP)nknown, (\fBv\fP)irtual. This groups logical volumes related to the same kernel target together. So, for example, mirror images, mirror logs as well as mirrors themselves appear as (\fBm\fP) if they use the original device-mapper mirror kernel driver; whereas the raid equivalents using the md raid kernel driver all appear as (\fBr\fP). Snapshots using the original device-mapper driver appear as (\fBs\fP); whereas snapshots of thin volumes using the new thin provisioning driver appear as (\fBt\fP). . .IP 8 Newly-allocated data blocks are overwritten with blocks of (\fBz\fP)eroes before use. . .IP 9 Volume Health, where there are currently three groups of attributes identified: . .IP Common ones for all Logical Volumes: (\fBp\fP)artial, (\fBX\fP) unknown. .br (\fBp\fP)artial signifies that one or more of the Physical Volumes this Logical Volume uses is missing from the system. (\fBX\fP) unknown signifies the status is unknown. . .IP Related to RAID Logical Volumes: (\fBr\fP)efresh needed, (\fBm\fP)ismatches exist, (\fBw\fP)ritemostly. .br (\fBr\fP)efresh signifies that one or more of the Physical Volumes this RAID Logical Volume uses had suffered a write error. The write error could be due to a temporary failure of that Physical Volume or an indication that it is failing. The device should be refreshed or replaced. (\fBm\fP)ismatches signifies that the RAID logical volume has portions of the array that are not coherent. Inconsistencies are detected by initiating a "check" on a RAID logical volume. (The scrubbing operations, "check" and "repair", can be performed on a RAID logical volume via the 'lvchange' command.) (\fBw\fP)ritemostly signifies the devices in a RAID 1 logical volume that have been marked write-mostly. Re(\fBs\fP)haping signifies a RAID Logical Volume is either undergoing a stripe addition/removal, a stripe size or RAID algorithm change. (\fBR\fP)emove after reshape signifies freed striped raid images to be removed. . .IP Related to Thin pool Logical Volumes: (\fBF\fP)ailed, out of (\fBD\fP)ata space, (\fBM\fP)etadata read only. .br (\fBF\fP)ailed is set if thin pool encounters serious failures and hence no further I/O is permitted at all. The out of (\fBD\fP)ata space is set if thin pool has run out of data space. (\fBM\fP)etadata read only signifies that thin pool encounters certain types of failures but it's still possible to do reads at least, but no metadata changes are allowed. . .IP Related to Thin Logical Volumes: (\fBF\fP)ailed. .br (\fBF\fP)ailed is set when related thin pool enters Failed state and no further I/O is permitted at all. . .IP Related to writecache logical volumes: (\fBE\fP)rror. .br (\fBE\fP)rror is set dm-writecache reports an error. . .IP 10 s(\fBk\fP)ip activation: this volume is flagged to be skipped during activation. . .SH SEE ALSO . .nh .na .BR lvm (8), .BR lvm.conf (5), .BR lvmconfig (8), .BR lvmdevices (8), .P .BR pvchange (8), .BR pvck (8), .BR pvcreate (8), .BR pvdisplay (8), .BR pvmove (8), .BR pvremove (8), .BR pvresize (8), .BR pvs (8), .BR pvscan (8), .P .BR vgcfgbackup (8), .BR vgcfgrestore (8), .BR vgchange (8), .BR vgck (8), .BR vgcreate (8), .BR vgconvert (8), .BR vgdisplay (8), .BR vgexport (8), .BR vgextend (8), .BR vgimport (8), .BR vgimportclone (8), .BR vgimportdevices (8), .BR vgmerge (8), .BR vgmknodes (8), .BR vgreduce (8), .BR vgremove (8), .BR vgrename (8), .BR vgs (8), .BR vgscan (8), .BR vgsplit (8), .P .BR lvcreate (8), .BR lvchange (8), .BR lvconvert (8), .BR lvdisplay (8), .BR lvextend (8), .BR lvreduce (8), .BR lvremove (8), .BR lvrename (8), .BR lvresize (8), .BR lvs (8), .BR lvscan (8), .P .BR lvm\-fullreport (8), .BR lvm\-lvpoll (8), .BR blkdeactivate (8), .BR lvmdump (8), .P .BR dmeventd (8), .BR lvmpolld (8), .BR lvmlockd (8), .BR lvmlockctl (8), .BR cmirrord (8), .BR lvmdbusd (8), .BR fsadm (8), .P .BR lvmsystemid (7), .BR lvmreport (7), .BR lvmcache (7), .BR lvmraid (7), .BR lvmthin (7), .BR lvmvdo (7), .BR lvmautoactivation (7)
