It would be nice if FreeBSD handled this better, but this problem falls into the "operator error: don't do that" category. > it doesn't have working software RAID (Ok, vinum never worked properly > but that's a different story), This is a valid point-- the migration to 5.x and gvinum has not been pretty, and there are some gotchas lurking when people try to deal with multi-terabyte RAID arrays, MBR vs GPT, and so forth. However, it's common to find half-decent hardware RAID functionality on many x86 and AMD64 motherboards, and PCI-based RAID cards are not very expensive. I'd rather use RAID in hardware than software, myself, but if you think the current status of software RAID in 5.x isn't production ready, that strikes me as an understandable position to hold. > and it's performance is sub-par. 5.3 and earlier especially have struck me as being noticably slower than 4.10 or so, but there have been significant improvements since then, and 5.4 and 4.1x seem to be comparable. To do better than a broad generalization, however, you really need to pick some tasks and do real benchmarking to compare what is really going on. -- -Chuck
