UTM 9.1 Hot-Standby-Cluster (2-Node) RAM-Upgrade

guawhitehawk
Hi,

today we got more RAM for our Servers. While upgrading them, we will have 4x2GB reserve so i wanted to upgrade our Dell PE R310 Servers (currently running UTM 9.1 with 4x2GB DDR3) to 6x2GB DDR3. The Servers can handle that without a problem.

My Question is: I wanted to shutdown the current slave, upgrade the RAM by adding 2x2GB (from 8GB to 12GB), restart the slave and let them sync, then do a manual Switch-Over and repeat that for the new slave (old master).

Is it a problem if the master and slave have different RAM Sizes for a small time?
