ZFSが落ちる？†

USBメモリのディスクイメージを消す†

他のインストールイメージを書き込んだUSBメモリーはWindowsなどではデータ消去出来ないので、以下のツールをつかいます。添付もしときます。

HPU_v2.2.3.exe

USBメモリへディスクイメージを書き込む†

http://www.pcbsd.org/en/get-it/90-isotope-downloads から"PCBSD9.0-x64-USBFULL.img"バージョンをダウンロードし，USBメモリに書き込み．

• Windowsでの書き込みにはDD for Windowsを利用するのが確実． http://www.si-linux.co.jp/wiki/silinux/index.php?DDforWindows

PC-BSD9　インストール†

http://gihyo.jp/admin/clip/01/fdt/201004/0016

PCBSD-9のイメージを書き込んだUSBで起動させ、FreeBSD9.0Rをインストールする。

1. HDD3台でraidz な Zpoolをつくる。
2. bootブロックは、ufs で

インストールログは、ココに書き込まれる。

えらくあっさりとインストールが終わるが、/usr/src とか、/usr/ports はインストールされない。

SWAPを造る†

http://lovepeers.org/2010/11/22/install_zfs-boot-enabled-freebsd_using_pcbsd_2/

# zfs create -V 8G tank0/swap
# zfs set org.freebsd:swap=on tank0/swap
# zfs set checksum=off tank0/swap

# zfs create -V 8G tank0/swap && zfs set org.freebsd:swap=on tank0/swap && zfs set checksum=off tank0/swap

リブートしないとSwapとして認識しないので、再起動
