my question is according to google search I need to umount the filesystem point in order to reduce its size.... so it means I will require that nobody uses the system? since /var logs a lot information?
I also have the option to reduce /root but I think is more complicated.
so what are the precautions in order to reduce /var/?
Hi Folks,
I'm wordering if I can ufsdump the /var fs from a server1 and create a new /var fs in Server2, that is because some damage happened in the /var fs and we don't have backup of it, I've tried fsck and no sucess at all..
Any ideia how I can recovery that /var fs ?
Thanks,

Hello guys,
I would like to ask you kindly if you don't know some quick and safe method how to shrink ext4 filesystem and reduce the size of a Logical Volume in Linux, please?
Thank you very much. (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] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] {-l|--extents
[-]LogicalExtentsNumber[%{VG|LV|FREE|ORIGIN}] | [-L|--size [-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]} [-n|--nofsck] [-r|--resizefs] Logi-
calVolume{Name|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(8) for common options.
-f, --force
Force size reduction without prompting even when it may cause data loss.
--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. The resulting value for the substraction is rounded downward, for
the absolute size it is rounded upward.
-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.
-n, --nofsck
Do not perform fsck before resizing filesystem when filesystem requires it. You may need to use --force to proceed with this option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
EXAMPLES
Reduce the size of logical volume lvol1 in volume group vg00 by 3 logical extents:
lvreduce -l -3 vg00/lvol1
