You can increase the data partition to suit the sizing need of Change Guardian server:
To increase the partition size:
Add a hard disk to the virtual machine.
Stop the Change Guardian services by running the following command: rcsentinel stop
Run the following command to list the partition that was added: fdisk -l
Format the new disk to ext3 file system by running the following command: mkfs.ext3 /dev/<partition1>
Create a temporary directory /tmp/new to copy files from /var or /opt.
Mount new partition to the temporary directory by running the following command: mount /dev/<partition1> /tmp/new
Move the data directory to the newly created directory. For example: mv /var/opt/* /tmp/new
Unmount the temporary directory by running the command: umount /tmp/new/
Mount the new partition to /var/opt/ by running the command: mount /dev/partition1 /var/opt/
Confirm that the data partition /var/opt is mounted by running the command: mount
Verify that the data partition /var/opt has moved to the new partition by running the command: df -h
