Environment

Cause

This can be caused by corruption of the bundle cache during the outage:

/opt/vmware/horizon/bundleCache

Resolution

Recreate the directory by following the steps below: 

1. SSH into the vIDM appliance as the root user.

2. Stop the Workspace service

service horizon-workspace stop

3. Remove the corrupted bundle cache

rm -rf /opt/vmware/horizon/bundleCache

4. Recreate the directory manually and set the correct ownership

mkdir -p /opt/vmware/horizon/bundleCache

chown horizon:www /opt/vmware/horizon/bundleCache

5. Start the Workspace service

service horizon-workspace start
