Extend Disk Space in the OVA with LVM

Add Harddisk Space in your Hypervisor Environment

Regardless of your Usage of VMWare, Xen, Hyper V or other, when you intend to grow the Diskspace of the eDMS OVA, it is neccesary to assign Diskspace to your VM

Please refer to the Manual of your Virtualization Platform for this.

The Standard Size while deploying the OVA is 100 GB. This will naturally not suffice anymore after a while of adding Documents, Versions Previews etc.

We cannot give a general Recommendation as to how large your extension should become, but please contact us if this is unclear in your specific Situation.

Make Disk visible to the OVA

SSH into the CentOS OVA and sudo to root (unless you are already root)
```
sudo su - 
```

List the block device to see the newly assigned vSphere hard disk.

lsblk

If you do not see the vSphere hard disk, force a rescan

for host in $(ls -1d /sys/class/scsi_host/*); do echo "- - -" > ${host}/scan ; done
for device in $(ls -1d /sys/class/scsi_disk/*); do echo "1" > ${device}/device/rescan ; done

create a new Partition that is compatible to LVM

Format the disk partition. Get the device name from the previous lsblk output

fdisk /dev/sdb
n (new partition)
p (primary)
(Press ENTER) (Use default partition number)
(Press ENTER) (Use default first sector)
(Press ENTER) (Use default last sector)

t (change the partition type)
8e (Linux LVM)

w (write)

Create the Physical Volume for LVM
and check afterwards with pvs
Extend the Volumegroup (vg).
first check for the group with "vgs" then "vgextend centos" then check again:
now extend the Logival Volume (lv)
first check for the Volume with "vgs" then "lvextend" then check again:
resize filesystem
now in order to actually use the additional space we need to resize the filesystem.
first check the existing file system

then actually resize the file system

and check again:
