DESCRIPTION vgdisplay allows you to see the attributes of VolumeGroupName or all volume groups if none is given with it s physical and logical volumes and their sizes etc vgs 8 is an alternative that provides the same information in the style of ps 1 OPTIONS See lvm 8 for common options A activevolumegroups Only select the active
Scan your system for LVM volumes and identify in the output the volume group name that has your Fedora volume mine proved to be VolGroup00 $ sudo vgscan Activate the volume $ sudo vgchange ay VolGroup00 Find the logical volume that has your Fedora root filesystem mine proved to be LogVol00 $ sudo lvs Create a mount point for that volume
The following will give you a list of the LV names with each value separated with a new line "n" sudo lvscan cut d " " f 2 Or if you just want the LV names only <lv name> sudo lvs noheadings o lv name tr d PV Name s You didn t ask but while I m at it this is how you would get PV names Physical Volume names
Reshaping a RAID Logical Volume Red Hat Enterprise Linux and Later Controlling I/O Operations on a RAID1 Logical Volume; Changing the region size on a RAID Logical Volume Red Hat Enterprise Linux and later Physical volumes are combined into volume groups VGs This creates a pool of disk space out of which
A physical disk is divided into one or more physical volumes Pvs and logical volume groups VGs are created by combining PVs You should read some more specified info here at The Linux Logical Volume Manager This picture pretty much sums it up Also there s some good information at A Beginner s Guide To LVM
Volume Groups VG A volume group is a pool of disk space made from one or more physical volumes Logical Volumes Wrapping Up Linux Logical Volume Manager In this comprehensive guide we ve delved into the world of the LVM command in Linux a powerful tool for managing disk drives in Linux We ve covered the basic to advanced usage
lvscan List all logical volumes in all volume groups SYNOPSIS lvscan [ option args] DESCRIPTION lvscan scans all VGs or all supported LVM block devices in the system for LVs The output consists of one line for each LV indicating whether or not it is active a snapshot or origin the size of the device and its allocation policy
all List all volume groups Equivalent to not specifying any volume groups aligned Use with separator to align the output columns 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
vgdisplay Display volume group information SYNOPSIS vgdisplay [ option args] [ position args] DESCRIPTION vgdisplay shows the attributes of VGs and the associated PVs and LVs vgs 8 is a preferred alternative that shows the same information and more using a more compact and configurable output format USAGE
Purpose Displays information about volume groups Syntax lsvg [ L] [ o ] [ n descriptorphysicalvolume] [ i ] [ l M p ] [ m] [ P] Description The lsvg command displays information about volume groups If you use the volumegroup parameter only the information for that volume group is displayed If you do not use the volumegroup
2 Managing LVM Volume Groups Physical volumes are combined into volume groups VG or A VG is a collection of physical volumes of varying sizes and types I have re added the deleted PV using the command pvcreate /dev/sdb1 Create Volume Group We can create a volume group from one or more physical volumes
Managing Volume Groups and Logical Volumes; Application Installs storage is handled a little differently then by the conventional single disk > Multiple Partition model Linux can use a function called Volume Manger to efficiently take multiple disks and /or multiple partitions combined into a single pool or Volume Group VolGroup00
To combine two volume groups into a single volume group use the vgmerge command You can merge an inactive "source" volume with an active or an inactive "destination" volume if the physical extent sizes of the volume are equal and the physical and logical volume summaries of both volume groups fit into the destination volume groups limits
Volume Groups List Volume Groups sudo vgdisplay Create Volume Group Volume groups are collections of physical volumes To create one you need to specify which volumes it should group/manage Linux Administration and IT solutions Need support with your infrastructure or web services Get in touch Programster s Blog Ⓒ 2025

The inactive SourceVolumeGroupName will be merged into the Destina‐ tionVolumeGroupName if physical extent sizes are equal and physical and logical volume summaries of both vol‐ ume groups fit into DestinationVolumeGroupName s limits
After re creating the dropped sdc physical volume we have all we need to create a volume group that can hold a logical volume We could create a volume group that has only one physical volume which is the exact case of the default sda2 but to demonstrate storage aggregation we ll use both our new physical volumes to create a volume group called
Ok now that we have nailed down the "what and why " let s configure a volume group using the two physical volumes illustrated above You can see the creation and initialization of these groups in my article How to create physical volumes in Linux using LVM We are going to combine /dev/sdb and /dev/sdc into a volume group First we will need
How do I set the volume list How do I do HA LVM and have the system actually boot I am using multiple local volume groups that need to be listed in the "volume list" in /etc/lvm/ What is the proper syntax for that Can I use wildcards in volume group names in "volume list" in /etc/lvm/ Environment Red Hat Cluster Suite 4
Reduce and Relocate Volume Groups on Oracle Linux Introduction The removal of a PV shrinks the overall size of the VG This tutorial will work with the Oracle Linux Volume Manager utilities to shrink a volume group by removing a physical volume and then transferring the volume group to another system Objectives In this tutorial you will
We have explained different ways to list groups in Linux for you The commands and methods used may vary according to habits You can use whichever method is faster and easier for you Of course the choice is yours You can get help with the h/ help parameter for each command For more detailed information you can also access the man page of
