CAM-ATA
意外に、さらっとできた。GPT-ZFSのみなので、fstabをいじる必要もないし。
config作成
こんな感じで。

buildkernel&reboot
通常通りに。
# cd /usr/src # make buildkernel KERNCONF=CAMATA # make installkernel KERNCONF=CAMATA # shutdown -r now
reboot後
どっかでsingle user modeに落ちるかなあと思って見てたけど、特に何も起きず。。。
adがadaに変わったくらい。

やっぱり512 byte sectorなのか。。。
デバイス名が変わって、zpoolの結果が面倒なことに。
$ zpool status
pool: pool1
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scrub: none requested
config:

errors: No known data errors逆にいえば、デバイス名が変わっても、GPTのID(?)をもとにちゃんと使えてるので、なんというか便利だ。labelが付け直せるかは、あとで調べる。
camcontrol
結果はこのような。

sector sizeの、physicalが4096になるのを期待したんだけど、ダメかー。まあ、なったところで何かが変わるかというと分からんが、少なくともここで4096にならなければ、変わらんわなあ。
150MB/s transferっていうのもなあ。ICH7がさぼってるのか。DMA supportedはUDMA6まであるのに、pass0はUDMA5とおっしゃっている、そういうものなのか？
