iSCSIをRasPiで使いたい
やりたいこと
Raspberry Pi 3をiSCSIターゲットにしたい。
TL;DR
https://blog.akimasa.jp/2018/09/11/raspi-iscsi-target/
https://blog.akimasa.jp/2018/01/15/build-iscsi-kernel/
iSCSI Enterprise Targetのパッケージiscsitargetは古いので、LIOターゲットを使うべき。らしい。LIOターゲットのパッケージであるtargetcli-fbはRaspbianに入ってはいるが、カーネルを自分でビルドしないと使えなさそう。
試行記録
Raspbianでiscsitarget-dkmsを入れようとしたら次のようなエラーが出た

raspberrypi-kernel-headersを入れてみたが、古いようでダメだった。
rpi-updateで入るかと思ったが、これでもダメだった。
調べてみて出てきたので、rpi-sourceを使ってみた。そのままではGCCのバージョンが違うようで実行できないので、rpi-source --skip-gccで通った。が、dkms autoinstallが通らない。
sudo apt install gcc-4.9 g++-4.9 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 20 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.6 20 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 50 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 50 cd ~/linux/ make clean make modules_prepare sudo dkms autoinstall
しかし、やはり通らない。

こんな記述を発見した。どうやら不要らしい。
と思いきや、 iscsitarget not enabled in "/etc/default/iscsitarget", not starting...で起動していなかったので言われたファイルを編集する。
モジュールが足りなくて起動しなかった。
よく調べたら、現在の標準はIETではなくLIOらしい。
そこで、targetcli-fbを入れたがサービス起動時に次のようなエラーが出てダメだった。target_coreがないらしい。

githubにそれっぽいissueがあったが、進展が今のところない。自分でカーネルをビルドしなおすしかなさそうな感じだった。
