*ZFS HDD交換2 [#k58531d1]

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

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。



        NAME                      STATE     READ WRITE CKSUM
        tank                      DEGRADED     0     0     0
          raidz1-0                DEGRADED     0     0     0

と、ada1が所定の？位置へ。
