Issue Summary:
We have identified that Security Package (SPACK) 2259, released on June 2, 2025, may introduce instability on certain VOS nodes, potentially causing them to go offline.

Affected Versions:

  • VOS 21.2.x

  • VOS 21.3.x


Impact Scope:
This issue affects only VOS nodes running versions 21.2.x or 21.3.x that have an IPS (vulnerability profile) configuration enabled.

Recommended Action / Remediation Steps:

To mitigate the impact, SPACK 2259 has been removed from the update repository. If your affected VOS nodes have auto-update enabled and are currently running SPACK 2259, please proceed with one of the following remediation options:

Option 1: Automated Remediation via Director

  1. Copy the attached script spack_revert.sh to the /var/tmp/ directory on the Director.

  2. Make the script executable:

    chmod a+x spack_revert.sh

  3. Run the script:

    bash -x ./spack_revert.sh

  4. After execution, check for a file named at /var/tmp/unreachable_ips.txt for unreachable devices.

  5. Re-run the script to attempt recovery of previously unreachable devices.

  6. For any nodes that remain unreachable, proceed with Option 2 below.

Option 2: Manual Remediation on Individual VOS Nodes

If the device is not reachable from the Director, use SSH (out-of-band) or console access to connect directly to the VOS node.

If services are continuously restarting or have stopped, run:

vsh on-vsmd-stop nothing 
vsh start 

cd /opt/versa/scripts 
sudo ./spack_revert.py 
vsh on-vsmd-stop default 
vsh restart

If services are stable, run:

cd /opt/versa/scripts 
sudo ./spack_revert.py

If you require assistance with these steps or have any questions regarding your deployment, please don’t hesitate to contact our support team.
