linux磁盤分區

1、 parted 磁盤分區
1）查看新加磁盤
[root@Tim ~]# ll /dev/sd
[root@Tim ~]# ll /dev/sd
brw-rw---- 1 root disk 8, 0 Jan 25 21:18 /dev/sda
brw-rw---- 1 root disk 8, 1 Jan 25 21:18 /dev/sda1
brw-rw---- 1 root disk 8, 2 Jan 25 21:18 /dev/sda2
brw-rw---- 1 root disk 8, 16 Jan 25 21:33 /dev/sdb
2）磁盤分區 輸入h查看parted 命令幫助
[root@Tim ~]# parted /dev/sdb
GNU Parted 2.1
