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
Regards

Hello. I have a test server that I'm messing around with, and just recently received an error on startup that a logical volume in the root volume group couldn't be re-synchronized. Server boots fine, as the root vg is mirrored, but I'd like to get rid of the error. Here are the details:

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)
Hi all,
How do u rename a logical volume group and the logical volumes belonging to that? The logical volumes contain data and are in use.
eg: Renaming dev/vgov to dev/ov-dg ? (6 Replies)
Hi!
Can anyone help me on how I can do a basic check on the Unix filesystems / physical volumes and logical volumes?
What items should I check, like where do I look at in smit? Or are there commands that I should execute?

Hello Guys,
I want to create a file system dedicated for an application installation. But there is no space in volume group to create a new logical volume. There is enough space in other logical volume which is being mounted on /var.
I know we can use that logical volume and create a virtual... (2 Replies)

lvreduce
LVREDUCE(8) System Manager's Manual LVREDUCE(8)NAME
lvreduce - reduce the size of a logical volume
SYNOPSIS
lvreduce [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [--noudevsync] {-l|--extents [-]LogicalExtentsNum-
ber[%{VG|LV|FREE|ORIGIN}] | -L|--size [-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]} [-t|--test] [-v|--verbose] LogicalVolume[Path]
DESCRIPTION
lvreduce allows you to reduce the size of a logical volume. Be careful when reducing a logical volume's size, because data in the reduced
part is lost!!!
You should therefore ensure that any filesystem on the volume is resized before running lvreduce so that the extents that are to be removed
are not in use.
Shrinking snapshot logical volumes (see lvcreate(8) for information to create snapshots) is supported as well. But to change the number of
copies in a mirrored logical volume use lvconvert (8).
Sizes will be rounded if necessary - for example, the volume size must be an exact number of extents and the size of a striped segment must
be a multiple of the number of stripes.
OPTIONS
See lvm for common options.
-f, --force
Force size reduction without any question.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
-l, --extents [-]LogicalExtentsNumber[%{VG|LV|FREE|ORIGIN}]
Reduce or set the logical volume size in units of logical extents. With the - sign the value will be subtracted from the logical
volume's actual size and without it the value will be taken as an absolute size. The number can also be expressed as a percentage
of the total space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the suffix %LV,
as a percentage of the remaining free space in the Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the
total space in the Origin Logical Volume with the suffix %ORIGIN.
-L, --size [-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Reduce or set the logical volume size in units of megabytes. A size suffix of k for kilobyte, m for megabyte, g for gigabytes, t
for terabytes, p for petabytes or e for exabytes is optional. With the - sign the value will be subtracted from the logical vol-
ume's actual size and without it it will be taken as an absolute size.
Example
"lvreduce -l -3 vg00/lvol1" reduces the size of logical volume lvol1 in volume group vg00 by 3 logical extents.
