It's recommended to add an external disk to any PAM server that is configured for screen recording. On high-usage systems, the external disk can become full and removing older recordings and archives is not an option.

The steps in this article detail how to add extra disk space to an existing external disk on a PAM server.

Applicable Versions

v7.2.0 onwards.


This article assumes the following:

  • All snapshots of the PAM Server have been removed.
  • The user account osirium_support has been enabled and a password set.
  • A backup of the Osirium server and the external filestore has been taken and stored in line with your backup procedure.

Extending the External Filestore Disk

1. Firstly, within the VMware Management Console, expand the external filestore disk being used by the PAM Server.

2. Using the PAM Server Console window, logon using the osirium_support account.

3. Rescan the PAM Server to pick up the changes:

sudo sh -c "echo 1 > /sys/class/scsi_device/32\:0\:1\:0/device/rescan"

4. To see the expansion to the external filestore disk type the following command at the prompt

sudo fdisk -l

5. Resize the physical volume in LVM:

sudo pvresize --verbose /dev/sdb

6. Check that the physical volume has got free space now

sudo pvdisplay /dev/sdb

7. Extend the logical volume to fill it:

sudo lvextend -l +100%FREE -r /dev/external/external

8. Check that the logical volume has been extended:

df -h
