Adding Disk Resources for a Junos Space Virtual Appliance
The Junos Space Virtual Appliance files are distributed with 250-GB of disk space.
The free space available in all the partitions should be monitored periodically and the available free disk space increased if required. The /var and /var/log partitions should be monitored more frequently as most of the data are stored in these partitions and space utilization is high.
For information about disk space needed for installing a Junos Space application, refer to the respective application documentation available at Junos Space Software, Release 15.1.
If you are expanding the disk space of nodes in a Junos Space fabric (cluster) comprising virtual appliances, you must first expand the disk space of the virtual IP (VIP) node and ensure that the VIP node has come up, that is, JBoss and MySQL services are up before expanding the disk space of other nodes in the fabric; otherwise, the fabric may become unstable and the Junos Space GUI inaccessible.
While configuring a Junos Space Virtual Appliance as a Junos Space node or an FMPM node, it is recommended that you allocate disk space partitions as per the disk space allocations for a JA2500 Junos Space Appliance. However, you can allocate less or more space to disk partitions as per your requirement. For more information about disk space allocation in JA2500 Junos Space Appliance, see Configuring a Junos Space Appliance as a Junos Space Node.
To allocate additional disk space for partitions, add a disk resource and expand a partition one at a time. The free space available on the disk resource can be shared among the different partitions. For example, to expand the /var and /var/log partitions by 20 GB each, add a disk resource of minimum 40 GB. Expand the drive size of the /var partition by 20 GB and then expand the /var/log partition by 20 GB.

The following tasks that must be performed for adding disk resources are explained in this topic:
Adding Disk Resources for a Junos Space Virtual Appliance Deployed on a VMware ESX or VMware ESXi Server
The Junos Space Virtual Appliance files are distributed with 500-GB of disk space by default in Junos Space Network Management Platform release 20.1R1 and above. You can increase the hard disk size based on the requirement for the specific Junos Space deployment. The following procedure describes how you can add disk resources for a Junos Space Virtual Appliance deployed on a VMware ESX or VMware ESXi Server.
To add disk resources for the Junos Space Virtual Appliance:
The next step is to configure the basic settings for your deployed Junos Space Virtual Appliance. To configure basic settings for the appliance, access the console in the VMware vSphere Client.
After the new virtual disk is created, the Junos Space Virtual Appliance must be scanned to detect the additional disk space that you added. To start the scan for additional disk space, select the Expand VM Drive Size option from the Junos Space Settings Menu immediately after you configure the basic settings for your Junos Space Virtual Appliance.
For information about expanding the drive size, refer to Configuring a Junos Space Virtual Appliance as a Junos Space Node.
Adding Disk Resources for a Junos Space Virtual Appliance Deployed on a KVM Server
The Junos Space Virtual Appliance file is distributed with 250 GB of disk space. You can increase the size of the hard disk based on the requirement for the specific Junos Space deployment. The following procedure describes how you can add disk resources for a Junos Space Virtual Appliance deployed on a KVM Server.
