It appears as though the disk was already allocated to the VM. Also, in this way, I personally believe it was done in an inefficient way.
What is the output of
Also, could you add disk to the physical server and then allocate that to the second virtual server?
How much memory exists on the physical machine as well as each virtual machine?
You may also want to run top on the physical machine, not to mention, if these are running SAP, depending on the disk subsystem, you may run into contention for I/O and slow both of them down.
Hi,
I have the following problem.
I just have a new machine with mirroring. The logical volume for /opt is dimensionned to 75 GB which is to much. I want a volume of 10 GB. How can I reduce the size ?
I tried to reduce the size of the slice from 75 GB to 10 GB, but the size of the logical volume... (6 Replies)

Hello,
I want to compress any given file or directory. I used
1)gzip
2)zip
But when I do "ls -l". I found that the zipped file is in fact greater in size than the original file.
Can you please tell me the commands which will show me the difference in its size. (2 Replies)
I'm trying to reduce hard drive size (number of cylinders) in SPARC Solaris. Its easy to change last cylinder of last slice, but that cannot be done for slice2/backupslice because it insists on whole disk. If I try to change disk type/geometry, all slices get replaced with some 'default'... (1 Reply)
Dear all,
i have a lot of .pdf files that i need to reduce size with pdf2ps and ps2pdf app. I need a script which i can reduce file size of all .pdf files in every subfolder of WORKDIR folder.

My volume group of size 200 gb.
out of which only 100 gb is used by 2 logical volumes /dev/vg00/lvol0 and /dev/vg00/lvol0 respectively (both are 50 gb each).
Whenever i use vgreduce command to reduce the size of volume group i get below error.

Hi All,
I have one logical volume with size as 900G and it is mounted as xfs file system.
Now I want to reduce this partition to 500G.
So I followed the below steps.

Reduced the volume using the command
Now I remounted the partition.
But the problem... (3 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.
-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 total number of physical extents freed will be
greater than this logical value if, for example, the volume is mirrored. 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 subtraction is rounded downward, for the
absolute size it is rounded upward. N.B. In a future release, when expressed as a percentage with VG or FREE, the number will be
treated as an approximate total number of physical extents to be freed (including extents used by any mirrors, for example). The
code may currently release more space than you might otherwise expect.
-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.
--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.
-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
