たけふ＠大阪豊中です
zfs の実験をしていて、障害発生時の対応を調べているのですが、
何処から手を付けていいやらで、zfs お使いの皆さんから、
ノウハウをお聞きしたく思います。
症状：
VMware Player の環境下で、10.2-RELEASE-p7(i386) 上で、
ホスト OS の再起動によって、umount せずに電源 OFF となった後の boot で、
zfs のマウント時に、コアダンプ吐いてリブートを繰り返す。
やった事：
シングルユーザーモードにて、以下のコマンドを実行すると、
すぐさまコアダンプ吐く。
zfs list
zpool list
やりたい事：
取り敢えず zfs のマウントがしたい。
まあ、データが救出できれば良いんですが...
「ここ確認した方が良いよ」とか「これこれやってみて」等、
アドバイスくださいm(__)m
以下に、設定ファイル等を記しておきます。
/boot/loader.conf
vfs.zfs.recover=1
vm.kmem_size="512M"
vm.kmem_size_max="512M"
vfs.zfs.prefetch_disable=1
kern.vty=vt
zfs_load=yes
/etc/rc.conf
keymap="jp"
dumpdev="AUTO"
keyrate="fast"
background_fsck="NO"
#zfs_enable=yes
注：zfs_enable は元々コメントしていませんでしたが、とりあえずブートさせるためにコメントにしてます。
