Can we update the existing Volume Group by adding a hard disk to the already existing
hello
Thanks for your quick reply.
i already have a hard disk which can hold a max of 146 gb .We are planning to add one more hard disk of 146 gb.
now we need to increase the size of a Logical Volume by increasing the space on the Volume Group.
Can you please tell me if i can update the existing Volume Group or do i need to create a new volume group for this ?
If so please let me know the procedure ...
Thanks in advance.

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

Does anyone have any simple methods for moving a current logical volume from one volume group to another? I do not wish to move the data from one physical volume to another. Basically, I want to "relink" the logical volume to exist in a different volume group. Any ideas? (2 Replies)

vgrename
VGRENAME(8) System Manager's Manual VGRENAME(8)
NAME
vgrename - rename a volume group
SYNOPSIS
vgrename [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-t|--test] [-v|--verbose] OldVolumeGroup{Path|Name|UUID} NewVol-
umeGroup{Path|Name}
DESCRIPTION
vgrename renames an existing (see vgcreate(8) ) volume group from OldVolumeGroup{Name|Path|UUID} to NewVolumeGroup{Name|Path}.
OPTIONS
See lvm for common options.
Examples
"vgrename /dev/vg02 /dev/my_volume_group" renames existing volume group "vg02" to "my_volume_group".
"vgrename vg02 my_volume_group" does the same.
"vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp"
changes the name of the Volume Group with UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to "VolGroup00_tmp".
All the Volume Groups visible to a system need to have different names. Otherwise many LVM2 commands will refuse to run or give
warning messages.
This situation could arise when disks are moved between machines. If a disk is connected and it contains a Volume Group with the
same name as the Volume Group containing your root filesystem the machine might not even boot correctly. However, the two Volume
Groups should have different UUIDs (unless the disk was cloned) so you can rename one of the conflicting Volume Groups with
vgrename.
