現状02/27・28¶
8TBのHDD5つが認識されていないためマウントする必要がある ここでHDDとminiPCのUSBを抜きなおししてしまった． dmesg(OSのから書き込まれるlog?)によれば[177933.518688]まではOS上では5枚のHDDだと考えられる「sda」「sdb」「sdc」「sdd」「sde」が認識されていた． しかし，[604106.481853]からそれぞれにエラーが発生しており，先ほどの抜き差しが原因だと考えられる． 今現在，ディスクの一覧を確認すると容量が300GBの「sda」とminiPCにもともと組み込まれているSSDが表示される この300GBの「sda」はおそらくiSCSIのインタフェースに内蔵されている容量だと考えられる．
OSに「sda」「sdb」「sdc」「sdd」「sde」をもう一度再認識させる必要がある． ・miniPCのリブート？再起動を行いもう一度認識させる？
どこで実行するのかどこを経由するのかを明確に図があるといいよね
02/29¶
前日のHDDの問題は解決した miniPCをリブートし，HDDラックの電源をOFF，もう一度電源を入れなおす．もう一度miniPCをリブート 以上で再認識することができた
再認識した結果
sudo fdisk -l
再認識された！！
