HPのG7は、ファイルシステム総てをZFSにした場合、再起動しない事があるので、/usr/homeだけをZFS化している。
ada1 ada2 ada3 で構成しているraidz1-0。で、ある日、ada1 が故障し、再起動すると・・・
NAME STATE READ WRITE CKSUM
tank DEGRADED 0 0 0
raidz1-0 DEGRADED 0 0 0
15956906539897666190 UNAVAIL 0 0 0 was /dev/ada1
ada1 ONLINE 0 0 0 block size: 512B configured, 4096B native
ada2 ONLINE 0 0 0 block size: 512B configured, 4096B native
errors: No known data errors
という風にada2 が ada1 へ。同様にada3がada2へ変化。
ここで、シャットダウンして、飛んだada1を交換し、起動。

と、ada1が所定の？位置へ。
