md0 : active raid1 sda3[0] sdb3[1]\n 972745176 blocks super 1.2 [2\/2] [UU]<\/pre>\nという構成です．とりあえず，sda3, sdb3を片割れずつ動かしてみましたが，どちらでも同じエラーが出ます．まあ，ミラーリングなので当たり前ですね．<\/p>\n
コピーでごまかす<\/h2>\n
とりあえず，md0を脱落させて，片割れになったアレーを新規のmd2（こちらも冗長性なし）に仕立てて，md0の内容をmd2にコピーして，md2から起動したところ，エラーが出なくなりました．<\/p>\n
どうも，このページの情報などからすると，ファイルシステムのエラー（ソフト的なエラー）のようです1<\/a><\/sup>後の注: 何をもってこの参照リンクから，「ファイルシステムのエラー（ソフト的なエラー）」と判断したか，今(2016\/09\/27)となっては不明です．<\/span>．<\/p>\n

ですから，あながちこの新たなドライブにコピーする，というのはごまかし的な対処でもないようです．<\/p>\n
md0の残党を殺して^^; md2にくっつけて，しばらく様子を見ます2<\/a><\/sup>その後，エラーは出ませんでした．結果よければすべてよしということで^^;<\/span>．<\/p>\n","protected":false},"excerpt":{"rendered":"
