xensystem 挂载磁盘 此文章转载自：http://blog.aoyohost.com/mount-ext3-formatted-disk.html  因为文章写得很详细，就不补充，只拷贝自己总结下原理：这就是虚拟一块磁盘给vps 用，vps 想用这块磁盘，需要格式化，挂载。 [root@MyVPS ~]# fdisk -l （查看磁盘分区） Disk /dev/xvdb: 7516 MB, 7516192768 bytes 255 heads, 63 sectors/track, 913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/xvdb doesn't contain a valid partition table Disk /dev/xvda: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/xvda1 * 1 13 104391 83 Linux /dev/xvda2 14 1044 8281507+ 8e Linux LVM /dev/xvda3 1045 1305 2096482+ 8e Linux LVM [root@MyVPS ~]# df -hal //*查看已划分区空间使用情况*// Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 9.3G 1.2G 7.7G 13% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys devpts 0 0 0 - /dev/pts /dev/xvda1 99M 29M 66M 31% /boot tmpfs 151M 0 151M 0% /dev/shm none 0 0 0 - /proc/sys/fs/binfmt_misc sunrpc 0 0 0 - /var/lib/nfs/rpc_pipefs [root@MyVPS ~]# fdisk /dev/xvdb //*对硬盘/dev/xvdb进行增加分区操作*// Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel.
