I joined the mdraid mailing list a couple months ago. I mostly lurk.
Most of the problems I see people have is when they try to grow / reshape a raid array, or when they have serious problems and try to fix it.
Surprising how many people post about experiencing a dual disk failure and need to try to rebuild without restoring backups. Apparently mdraid is a little aggressive about kicking drives out of the array, because often they are able to get the array operational again with exactly the same hardware.
I'm still a hardware raid guy, and having monitored the mdraid list for a couple months, I'm likely to stay one until mdraid becomes more tolerant of transient issues.
To be fair, hardware raid may be just as problematic in situations where power supplies, cables, external enclosures are behaving erratically. I just have not watched their support channels so closely.

I don't beat up on my drives or anything like that, but my experience with the software raid has truly been that I set them up, check them once, and then forget about them. I have had some spinning for 2 years now without a hiccup. (knock on wood). I am fairly cautious though. When I set one up, I used matched pairs of drives (nothing special, just 2 of the same type ordered at the same time) check that all is good with mdadm or dmraid or just watch the bios output if it is a bios raid, and that is all the thought my arrays ever get. The only death nail I see, which would hold true for hardware of software raid, is memory corruption that spews gibberish all over you drives. Raid or not, if that happens, you better have a backup handy... -- David C. Rankin, J.D.,P.E.
