This being said, there are a number of huge advantages to extend your Diskspace via LVM over other means (e.G. you do not have to split up your storage over several logical mountpoints) and this has proven to be reliable, scalable and fast.

Should you have the need for increasing your Diskspace and are not feeling comfortable with this procedure, please feel free to contact Patrix, Serviva or Pace-Ip for assistance.

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

• Prior to proceeding, you must identify the current LVM configuration and number of existing primary partitions.
  • If you already have 4 primary partitions (sda1, sda2, sda3, sda4), you will need to add the additional space as a new disk (sdb X).
  • If you don't have 4 primary partitions, you may add a new partition to the existing.

• 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 (or reboot which is less elegant but just as effective)

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 Swap

• 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) w (write)

  in order to see this partition, read the partition table with "partprobe" (or reboot which is less elegant but just as effective)

Activate the new Partition

partprobe

Verify the new partition is available

[root@cltdemo005 dev]# lsblk

Create the Physical Volume for LVM Swap

and check afterwards with pvs

pvcreate /dev/sdb1

Extend the Volumegroup (vg).

first check for the group with "vgs" then "vgextend centos" then check again:

vgextend centos /dev/sdb1

Disable swapping

first check for the group with "vgs" then "vgextend centos" then check again:

swapoff -v /dev/centos/swap

now extend the Logical Volume

Insteaf of the 31G here insert the size of your new swap disk:

 lvresize /dev/centos/swap -L +31G

format the extended swap volume

mkswap /dev/centos/swap

enable the logical volume

swapon -va

check the newly extended swap space
