在 CentOS 7 上設置 grub2 此文章主要以 Things to Know About Grub2 為基礎，而對象是那些開啟 /etc/grub2.cfg（或 /boot/grub2/grub.cfg）編輯開機選單的用戶。 另外請參閱 上游關於 grub2 的文檔 和 grub 的使用手冊。 1. 開機選單是自動建立出來的 請勿嘗試手動編輯開機選單，因為它是按照 /boot/ 目錄內的檔案自動建立出來的。然而你可以調整 /etc/default/grub 檔內定義的通用設定，及在 /etc/grub.d/40_custom 檔內加入個別自訂項目。 /etc/default/grub

http://cyrilwang.blogspot.tw/2013/09/glusterfs.html 去年我介紹過利用 lsyncd 這個套件來達成目錄的同步備援，今天則要利用 glusterfs 來達成類似的效果。雖說類似，但是 lsyncd 與 glusterfs 相比有下列差別： * lsyncd 監測目錄的變動，並定期 (或達到一定的異動次數) 將異動同步到另外一個目錄。因為 lsyncd 採用 inotify 監測技術，所以如果目錄內的檔案或子目錄一多，就可能會產生無法監測的問題。 * lsyncd 本身並沒有支援高可用性，必須利用其它機制 (如 heartbeat) 來達成高可用性。 * 被同步的目錄通常僅能當做備援，無法作為負載平衡之用。不但在資源使用上較為浪費，擴充性也比較差。 嚴格來說，拿 lsyncd 與 glusterfs 相比並不是一件公平且合理的事情，因為 glusterfs
