...similar fashion, enterprise UPSes are known to raise an FSD to their subscribers, if manually powered on before criticality thresholds are cleared, since they can't guarantee a safe shutdown to keep data intact, if wall power gets lost again).

Same here, quite at a loss what is handled where on the server and always low on time due to other projects/tasks. Cheers and any pointers appreciated!

...ver. Gluster's replication will serve as kind of fail- safe net and data redistribution will help, when we add more similar machines later on to counter increased usage. Thanks a lot in advance for at least reaching the end of my email, any help appreciated.

My $0.02: LB is baked in to nut behavior. So if a UPS doesn't report LB, then it makes sense to synthesize it. Synthetic LB is the cleanest fix at the earlier processing point. One could have a config that is basically synthetic-lowbatt-percent that generates LB if (as Jim says) on battery, not calibrating, and batt% <= that. One could have a similar config
