I don't have a recent R80.40 Azure CloudGuard management server anymore. They were all re-deployed with R81.20 and migrated over. This is an R81.20 /etc/fstab:

For this host, in the deployment parameters JSON, I configured 800GB for the "additionalDiskSizeGB" value. Maybe it was just 750GB. I don't seem to have that lying around anymore.
