这个容量对吗
可以使用fdisk -l进行磁盘数量的查看,参考我的(经济B),有两个磁盘(/dev/xvda和/dev/xvdb,数据盘未分区):
Disk /dev/xvda: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders, total 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0002bfb2
Device Boot Start End Blocks Id System
/dev/xvda1 * 2048 41940991 20969472 83 Linux
Disk /dev/xvdb: 85.9 GB, 85899345920 bytes
255 heads, 63 sectors/track, 10443 cylinders, total 167772160 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/xvdb doesn't contain a valid partition table
