推 rein: yaml 丟上來看看, 看起來是 config parse 問題 01/16 17:54
我用CentOS-7-x86_64-LiveGNOME-1511.iso 跑live DVD，救援資料用iSCSI
很多時候超好用，但是CentOS6用tgtd都沒問題，現在7版改用targetd，
卻一直失敗。

以上是targetcli設定狀況，現在我要看status
[root@localhost ~]# systemctl start targetd
[root@localhost ~]# systemctl status targetd

我搞不懂/etc/target/targetd.yaml是要幹嘛，但我還是把root密碼丟進去再啟動
[root@localhost ~]# systemctl start targetd
[root@localhost ~]# systemctl status targetd

問題好像越來越大了，請問有人知道這是怎模回事嗎？

"Don't hate the player. Hate the game."
當看到哪個名人賺了大錢，領到高額補助或利息，不要去指責他，
而是要指責那個制度、創造那個制度的人，以及默許那個制度的人。
不然你認為一個人不領18%或是一個人不炒房價，就會改變整體環境嗎？
還不如改變【修改制度的人】，才能從根源改變一切。
