Please wrap all code, files, input & output/errors in CODE tags.
It makes it far easier to read and preserves multiple spaces for indenting or fixed-width data.

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

Hi!
Can anyone help me on how I can do a basic check on the Unix filesystems / physical volumes and logical volumes?

Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies
1)Physical Volume

4)Physical Partition
Please help me to understand these concepts. (6 Replies)

Hello everyone,
I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.
Can anyone help me understand the utility... (11 Replies)
Hello Guys,

I know we can use that logical volume and create a virtual... (2 Replies)

lvextend
LVEXTEND(8) System Manager's Manual LVEXTEND(8)NAME
lvextend - extend the size of a logical volume
SYNOPSIS
lvextend [-A|--autobackup {y|n}] [-d|--debug] [-h|--help] {-l|--extents [+]LogicalExtentsNumber| -L|--size [+]LogicalVolumeSize[kKmMgGtT]}
[-v|--verbose] LogicalVolumePath [PhysicalVolumePath...]
DESCRIPTION
lvextend allows you to extend the size of a logical volume. Extension of snapshot logical volumes (see lvcreate(8) for information to cre-
ate snapshots) is supprted as well.
OPTIONS
-A, --autobackup y/n
Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes.
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-h, --help
Print a usage message on standard output and exit successfully.
-l, --extents [+]LogicalExtentsNumber
Extend or set the logical volume size in units of logical extents. With the + sign the value is added to the actual size of the
logical volume and without it, the value is taken as an absolute one.
-L, --size [+]LogicalVolumeSize[kKmMgGtT]
Extend or set the logical volume size in units in units of megabytes. A size suffix of M for megabytes, G for gigabytes or T for
terabytes is optional. With the + sign the value is added to the actual size of the logical volume and without it, the value is
taken as an absolute one.
-v, --verbose
Gives verbose runtime information about lvextend's activities.
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of that logical volume by 54MB on physical volume /dev/sdk3. This is
only possible if /dev/sdk3 is a member of volume group vg01 and there are enough free physical extents in it.
DIAGNOSTICS
lvextend returns an exit code of 0 for success or > 0 for error:
1 no logical volume name on command line
2 invalid physical volume name on command line
3 invalid logical volume name
4 error checking existence of logical volume
5 logical volume not active
6 error reading VGDA
7 requested physical volume not in this volume group
8 error getting index of logical volume
9 logical volume size not bigger than before
10 logical volume size exceeds volume group free capacity
11 logical volume size exceeds maximum
12 error setting up VGDA for logical volume extension
13 error extending VGDA for logical volume in kernel
14 error writing VGDA to physical volume(s)
15 error getting index for read/write statistics transfer
16 error getting status of logical volume from kernel
17 error setting up copy on write exception table
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
ENVIRONMENT VARIABLES
LVM_AUTOBACKUP
If this variable is set to "no" then the automatic backup of VG metadata is turned off.
LVM_VG_MAX_BACKUPS
This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It can be set to a positive number
between 0 and 999. The higher this number is, the more changes you can restore using vgcfgrestore(8).
LVM_VG_NAME
The default Volume Group Name to use. Setting this variable enables you to enter just the Logical Volume Name rather than its com-
plete path.
