10GB is indeed very small, if you make your initial disk larger the surplus will be added to the log partition, but if you decide to increase the log partition later that partition will be lost
you can add a second disk, it will mount as sdb1:
admin@Panorama> show system disk-space
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 3.8G 1.6G 2.1G 44% /
/dev/sda5 7.6G 1.5G 5.8G 20% /opt/pancfg
/dev/sda6 3.8G 1.9G 1.7G 54% /opt/panrepo
tmpfs 1005M 0 1005M 0% /dev/shm
/dev/sdb1 16G 195M 15G 2% /opt/panlogs
if you look at the partitions, the previos sda8 partition will have unmounted in favor of the newly added sdb

so you could opt to stick with the initial 10gb of log partition, then migrate to a larger secondary disk. if at one point you need even more space you could export the logs, unmount the secondary, mount a larger secondary, import logs
