You could also move the existing Spectrum installations out of the root partition - provided the new directory is the same as the old one.
For example, if the install is currently located in /opt/CA, then:
- Shutdown Spectrum (completely, including processd)
- Move /opt/CA to something else
- Create a new LVM volume for /opt/CA and mount it (obviously this will be non-root)
- Move the entire directory back into place
- Start Spectrum back up again
The usual caveats apply - do this at your own risk, etc. However, it will work and means that you don't end up filling your root partition with junk (log files, old reports, big databases, backups, etc.) and lock yourself out of the box.
I should also add that this is applicable to a Linux install of Spectrum. For Windows it might be a little more tricky...
