ネットワークコピーだと徐々に速度が落ちていく。動画を除きほぼ1日がかりで終了。全部で200G未満だがそれでも時間がかかるなぁ。
mdadm --assemble /dev/md/0 /dev/sd[a-d]1
mdadm --assemble /dev/md/1 /dev/sd[a-d]2
mdadm --assemble /dev/md/data-0 /dev/sd[a-d]3 mdadm: /dev/md/data-0 assembled from 2 drives and 1 spare - not enough to start the array.
mdadm -v -A --force /dev/md/data-0 /dev/sd[a-d]3
そうしたら再構築が強制的に始まっていた・・・。4時間以上まってから再接続で無事救出成功。次回以降は矯正認識不要で、自動マウントまでされる。

マニュアル用語でいうところの垂直な拡張 1本ずつ交換し、再構築が終わったらさらに一本。全部終わったら再起動すると容量が増える。
xraidだとトラブルがあるというし整理する意味できちんとバックアップしてから。
ほっとスワップなのにまったく抜けない(思い切り引っ張らないとだめ)、2台抜いてジエンド。もう二度と使わない!6tb*4にして再構築92時間。

df -h するとmd127が/dataに当てられており、/dev/md0はシステム系に当てられている。 md1はどこにも割り当てられていない。

MP3を全部コピーしようとしたら認識しなくなっていた。USBメモリの問題である可能性が高いが少しずつコピーさせるべし!
