Usually, FreeBSD can boot just fine without user interaction when power fails or there's some other cause for a "hard" OS failure (e.g. a kernel panic). That it isn't doing so in your case is significant, because it may point to serious problems. Firstly, what is the server used for? Do you have unusually high load on the file system - a busy file server or a database with lots of writes? - The default is for the root partition to be mounted "noasync" and Soft-updates to be used for all other file systems. Both settings can handle "hard" OS failures pretty good. Did you alter the default settings when creating the file systems? If you don't know, send the output of "mount" command. - How are your drives set up? Are they on a "dumb" disk controller or on a RAID controller? (which one?) Is the RAID controller perhaps doing write caching without a battery unit? - Can you connect the UPS devices with the server machines so they can shutdown gracefully when the power is about to fail?
