"/proc/drbd"中顯示了drbd當前的狀態.第一行的st表示兩臺主機的狀態,都是"備機"狀態.

ds是磁盤狀態,都是"不一致"狀態.

這是由於,DRBD無法判斷哪一方爲主機,以哪一方的磁盤數據作爲標準數據.所以,我們需要初始化

在serverC上執行:

[[email protected] ~]# drbdsetup /dev/drbd0 primary –o

主備機狀態分別是"主/備",主機磁盤狀態是"實時",備機狀態是"不一致".

在第3行,可以看到數據正在同步中,即主機正在將磁盤上的數據,傳遞到備機上.現在的進度是[>...................] sync'ed: 0.4% (1040316/1040316)K

稍等一會,在數據同步完後,再查看一下ha1的DRBD狀態:

磁盤狀態都是"實時",表示數據同步完成了.

你現在可以把主機上的DRBD設備掛載到一個目錄上進行使用.備機的DRBD設備無法被掛載,因爲它是用來接收主機數據的,由DRBD負責操作.

在serverC執行

[[email protected] ~]# mkfs.ext3 /dev/drbd0 //網上這裏有很多不同的版本，具體drbd深入我還沒有研究，我現在安裝的版本是隻要在第一臺上面格式化文件系統，他會自動傳過去。如果你在serverD上格式化，他會提示出錯，而且格式化要在上面相應工作做完以後纔可以到這一步。
