Troubleshoot Storage Capacity Warning

When Tenable Tenable One OT Exposure displays the following warning, the /opt partition has reached 85% of its capacity:

Your system has reached 85% storage capacity and is running low on space.

Complete the following steps to identify what is using the storage space and free up disk capacity.

Before you Begin

Confirm you have root or sudo access to the system.
Confirm that the system is running normally and you do not need to revert to a previous version.

Diagnose the Issue

Run the following command to inspect allocated and used disk space:
Copy
```
df -h
```

Run the following command to determine which directories use space under /opt:
Copy
```
sudo du -shc /opt/*
```

Free Up Space

Delete extracted installation files:
Copy
```
sudo rm -rf /opt/genesis/extracted
```
Remove previous installation backups in /opt/genesis/installations.
- To remove all backups, delete all files and directories in the directory.
- To keep the most recent backup, delete every directory except the one for your current version (for example, Cobex_4_7_56).
- Run the following command to inspect the /opt/indegy directory:
  Copy
```
sudo du -shc /opt/indegy/*
```
  Note: If a directory is unexpectedly large, contact Tenable Support.

Next Steps

If storage space remains insufficient, on a virtual machine with default specifications, allocate more space to the /opt partition. For instructions for extending the /opt partition, see the Add or Expand Disk Space in the Tenable Core User Guide or contact Tenable Support.
