DESCRIPTION

lvresize resizes an LV in the same way as Mall:man and Mall:man. See Mall:man and Mall:man for more information.

In the usage section below, Mall:ic Size can be replaced with Mall:ic Number. See both descriptions in the options section.

USAGE

Resize an LV by a specified size:

Mall:ic

Resize an LV by specified PV extents:

Mall:ic

Resize a pool metadata SubLV by a specified size:

Mall:ic

LV1 types: Mall:ic

Common options for command:

Mall:ic

Common options for LVM:

Mall:ic

OPTIONS

  • --alloc contiguous|cling|cling_by_tags|normal|anywhere|inherit

  • --commandprofile String
 The command profile to use for command configuration.
  • --config String
 Config settings for the command.

 Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file and/or syslog.
  • --devices PV
 Devices that the command can use.

 A file listing devices that LVM should use.
  • --driverloaded y|n
 If set to no, the command will not attempt to use device-mapper.
  • -l|--extents [+|-]Number[PERCENT]
 Specifies the new size of the LV in logical extents.
  • -f|--force
 Override various checks, confirmations, and protections.
  • -h|--help
 Display help text.
  • --journal String
 Record information in the systemd journal.
  • --lockopt String
 Used to pass options for special cases to lvmlockd.
  • --longhelp
 Display long help text.
  • -n|--nofsck
 Do not perform fsck before resizing filesystem when filesystem requires it.
  • --nohints
 Do not use the hints file to locate devices for PVs.
  • --nolocking
 Disable locking.
  • --nosync
 Causes the creation of mirror, raid1, raid4, raid5, and raid10 to skip the initial synchronization.
  • --noudevsync
 Disables udev synchronization.
  • --poolmetadatasize [+]Size[m|UNIT]
 Specifies the new size of the pool metadata LV.
  • --profile String
 An alias for --commandprofile or --metadataprofile, depending on the command.
  • -q|--quiet
 Suppress output and log messages.
  • --reportformat basic|json
 Overrides current output format for reports.

 Resize underlying filesystem together with the LV using fsadm(8).
  • -L|--size [+|-]Size[m|UNIT]
 Specifies the new size of the LV.
  • -i|--stripes Number
 Specifies the number of stripes in a striped LV.
  • -I|--stripesize Size[k|UNIT]
 The amount of data that is written to one device before moving to the next in a striped LV.
  • -t|--test
 Run in test mode.
  • --type linear|striped|snapshot|raid|mirror|thin|thin-pool|vdo|vdo-pool|cache|cache-pool|writecache
 The LV type, also known as "segment type" or "segtype".
  • -v|--verbose
 Set verbose level.
  • --version
 Display version information.
  • -y|--yes
 Do not prompt for confirmation interactively but always assume the answer yes.

VARIABLES

  • LV
 Logical Volume name.
  • PV
 Physical Volume name.
  • String
 See the option description for information about the string content.
  • Size[UNIT]
 Size is an input number that accepts an optional unit.

ENVIRONMENT VARIABLES

See Mall:man for information about environment variables used by LVM.

EXAMPLES

 Mall:ic
  • Resize an LV to use 50% of the size volume group:
 Mall:ic
