何言ってるか解らない題だと思いますが，自分宛のメモです．<\/p>\n\n\n\n

現在Linux WSの第1 OSはManjaro，第2 OSはDebianです．両OSは同じ1TBのSSDのパーティションにあります（だいたい半分ずつ）．このほか仮想マシン（KVM\/QEMU）のディスクイメージを保存するのに2TB SSDを，そのディスクイメージをバックアップするために3TB HDDを，ManjaroとDebian本体をバックアップするのに2TB HDDを使用してきました1<\/a><\/sup>4基ともPCの筐体内に設置してあります．<\/span>．<\/p>\n\n\n\n

そのバックアップ用の2TB HDDが数日前から不調で，バックアップのためマウントしようとしても出来ません．取り出して外部のSATA用のアダプターに接続したら読み出すことが出来たので，手持ちの1TB SSD 2基に中身をコピーしました．<\/p>\n\n\n\n

この不調が生じたのとほぼ同時期からDebianがブートしなくなりました．<\/p>\n\n\n\n

よく考えてみると，Debianはバックアップ用のHDDの第1パーティションをEFIに使っているのです．メインOSのManjaroが自分のドライブの第1パーティションとしているのでDebianはそこを使えないためです．<\/p>\n\n\n\n

もちろんManjaroのEFIから導かれたGRUBにはDebianも表示されますが，Debianが主体のEFI\/GRUBがあった方が便利です2<\/a><\/sup>とはいえなかなか煩雑ではあります．<\/span>．<\/p>\n\n\n\n

このため，DebianのEFI\/GRUBが置かれたバックアップ用の2TB HDDが不調になったらDebianはブートできないのです（起動時にマウントすべきEFIパーティションが見つからないため）．<\/p>\n\n\n\n

2TB HDDの後任には2TB SSDを新規購入してあてがいました．今どき2TBだとSSDはHDDとほとんど値段が変わらなくて驚きました．<\/p>\n\n\n

2基の1TB SSDに待避したバックアップの中身を新規購入したSSDへコピーしましたが速いです．なんか，バックアップ用にするのはちょっともったいない気もします．<\/p>\n","protected":false},"excerpt":{"rendered":"
