KFS 正式部署的時候遇到的問題

[b]一，大硬盤掛載[/b]

1 查看所有的磁盤

sudo fdisk -l |more 

2 設置磁盤

sudo fdisk /dev/sdb 

-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u')
WARNING : DOS

Command (m for help):c <enter>
DOS Compatibility flag is not set (不兼容DOS的模式，如果不用這個模式不能把硬盤設置成1T以上的)

Command (m for help): m <enter>
Command action
a   toggle a bootable flag
b   edit bsd disklabel

3 格式化硬盤

sudo mke2fs -t ext3 /dev/sdb1

4 自動掛載

sudo nano /etc/fstab

加入以下信息
/dev/sdb1 /mnt/kfs ext3 defaults 0 2

注意掛盤的時候一定要掛自己建立的文件目錄，這樣纔可以很隨意的換硬盤


[b]二 修復了Ubuntu 變成了只讀文件系統的錯誤[/b]

發現修改/etc/fstab，提示只讀文件系統，:w!也失敗。

運行以下語句即可

mount /dev/sda1 / -o rw,remount

[b]三 SSH 配置互通[/b]

只需修改 authorized_keys 的IP 爲 192.168.1.*即可達到通配的效果
