Visual LVM

unzip the Visual LVM Remote install package and run 'sudo ./visual-lvm-install.sh install' to install.

It is install script bug of Visual LVM MKIII Remote Step 575 before, and occurs in some 64bit Linux distro.

Try command 'ln -s /usr/visual_lvm/libBackendWaiter.so /usr/lib/libBackendWaitor.so' to handle it.

CAUTION: Here we supposes that the Visual LVM was installed in path '/usr/visual_lvm', if you installed it to other path, please replace the install path.

The Visual LVM Remote Step 575 before does not support systemd,so you need to create start-up script manually.

Create file '/usr/lib/systemd/system/visual-lvm.service'.

Copy followed text into it.

Run command 'systemctl enable visual-lvm.service'.

After list steps,the Visual LVM Remote will run after system start-up. If you want to stop Visual LVM automatically starting.

Run command 'systemctl disable visual-lvm.service'.

run 'sudo [Visual LVM Remote install path]/visual-lvm-install.sh remove' to uninstall.

The Visual LVM Standard must run with root privillege, so you need to type 'sudo ./visual_lvm' or run it with root account.

The Visual LVM Remote must run with root privillege, so you need to type 'sudo vlvmstart start' or run it with root account.

Once registered, the user is granted an exclusive license to use. Visual LVM on one computer, for any legal purpose, at a time. You need a license for one machine on which the program is installed. The registered Visual LVM software may not be rented or leased but can be permanently transferred, if the person who receiving it agrees to the terms of this license. If the software is updated, the transfer must include the update and all previous versions.

Download the binary match your platform from download page, and extract it. Double click file 'visual_lvm' or go to Visual LVM folder and type './visual_lvm' in in console.

Run command 'vlvmstart start'.

Please check whether selected partition was mounted for use. User cannot create Physical Volume on mounted partition.

It is forbidden to delete a Physical Volume in Volume Group, to delete a Physical Volume, user need to remove it from Volume Group first.

It is forbidden to delete a Volume Group with Logical Volume, to delete a Volume Group, user need to delete all Logical Volume(s) in Volume Group first.

Confirm if the Logical Volume is mounted or which is source of snapshot Logical Volume.

It is forbidden to remove a Physical Volume which is used by certain Logical Volume, to delete the Physical Volume, user need to delete all component(s) in it first.It is forbidden to remove a Physical Volume which is used by certain Logical Volume, to delete the Physical Volume, user need to delete all component(s) in it first.

To create RAID class logical volume, user need to select correct Physical Volume count.

For Simple : 1+ Physical Volume

For Stripe/Mirror : 2+ Physical Volumes

For RAID4/5 : 3+ Physical Volumes

For RAID6 : 5+ Physical Volumes

For StripeMirror : 4+ (must be even) Physical Volumes

And select the type. The relative type will not be enabled for selecting with incorrect Physical Volume count.

User can input value in Volume Size input box or drag the bar twinkling on selected section to resize volume.

Make sure the allocation type of Logical Volume is not "contigious". You can only select Physical Volume section adjacent with tail of existing instance in Logical Volume.

It is combined by 2 twinkling bars, the left one is belongs to tail section of Logical Volume, it is used to reduce volume size; the other one is belongs to first section on new selected area, it .is used to extend volume size.

Make sure the selected Physical Volume count is match with set of current Logical Volume(except for Stripe type Logical Volume, it can be expanded with any count of Physical Volume). You can only enlarge volume with the same Physical Volume count of its original set.

Check whether the other section was full selected for complex type Logical Volume.

The size of Logical Volume is multiple of Physical Extent, so the actual size of Logical Volume may not match the specified size. To get the size user wanted, who should set the size to a multiple of physical extents that exceeds the required size.

For logical volume in complex types (e.g. mirror/stripe mirror/raid4/5/6), the stripe count must be the same in all segments but stripe type.

Note for different segment of a stripe volume, stripe count can be different.

For instance, in a stripe volume consists 3 segments, the stripe count in each segments maybe 5,2,3 respectively.

The LVM(Logical Volume Management) is a system of managing logical volumes, or filesystems, that is much more advanced and flexible than the traditional method of partitioning a disk into one or more segments and formatting that partition with a filesystem.
