KFS 正式部署的时候遇到的问题
一，大硬盘挂载1 查看所有的磁盘
sudo fdisk -l |more
2 设置磁盘
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 : DOSCommand (m for help):c <enter>DOS Compatibility flag is not set (不兼容DOS的模式，如果不用这个模式不能把硬盘设置成1T以上的)Command (m for help): m <enter>Command actiona toggle a bootable flagb edit bsd disklabelc toggle the dos compatibility flagd delete a partitionl list known partition typesm print this menun add a new partitiono create a new empty DOS partition tablep print the partition tableq quit without saving changess create a new empty Sun disklabelt change a partition's system idu change display/entry unitsv verify the partition tablew write table to disk and exitx extra functionality (experts only)Command (m for help):n <enter>Command actione extendedp primary partition (1-4)p <enter>Partition number (1-4):1 <enter>Command (m for help):wThe partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.
3 格式化硬盘
sudo mke2fs -t ext3 /dev/sdb1
4 自动挂载
sudo nano /etc/fstab
加入以下信息
/dev/sdb1 /mnt/kfsext3defaults02
注意挂盘的时候一定要挂自己建立的文件目录，这样才可以很随意的换硬盘
二 修复了Ubuntu 变成了只读文件系统的错误
发现修改/etc/fstab，提示只读文件系统，:w!也失败。
运行以下语句即可
mount /dev/sda1 / -o rw,remount
三 SSH 配置互通
只需修改 authorized_keys的IP 为 192.168.1.*即可达到通配的效果
