As these systems age past two years drives are starting to fail and given that I can't monitor the state of the RAID arrays from FreeBSD I'm not purchasing any more MegaRAID controller based systems. Furthermore, although I haven't been able to definitively isolate it, I suspect that some mysterious hangs on some of our more heavily loaded database systems are due to the MegaRAID controller not gracefully handling failed drives, even when hot spares are available. I have zero diagnostic information as FreeBSD just stops responding (no console keyboard response, nothing...). I suspect this is due to the fact that my root partition is on the MegaRAID controller. This is also with the latest firmware installed on the MegaRAID controllers. So, what are people's experiences with the Adaptec 2200S U320 controller under FreeBSD 4.x and 5.x?
