基础知识

FreeBSD分区描述符为从"a"到"h"的8个字母。根据惯例，分区"c"被保留用作描述整个磁盘，"a"用作标识根分区，"b"用作标识交换分区。对于新添加的硬盘，我们常常只建立一个分区，标识为"e"。

IDE硬盘标记为ad，而SCSI硬盘标记为da，从0开始计数，因此，我们新添加的IDE硬盘将作为ad1出现在系统中。


一般步骤

把新的IDE硬盘接入系统，并确认开机以后系统找到了新添加的硬盘。可以通过检查/var/run/dmesg.boot来确认系统是否找到新添加的硬盘。

准备

vms# dd if=/dev/zero of=/dev/rad1 bs=1k count=1

1+0 records in

1+0 records out

1024 bytes transferred in 0.000822 secs (1245640 bytes/sec)

vms#

初始化磁盘

vms# fdisk -BI ad1

******* Working on device /dev/ad1 *******

fdisk: invalid fdisk partition table found

vms#


建立FreeBSD分区


vms# disklabel -B -w -r ad1s1 auto

vms# Feb 23 14:01:40 /kernel: ad1: cannot find label (no disk label)

Feb 23 14:01:40 /kernel: ad1s1: cannot find label (no disk label)

Feb 23 14:01:40 /kernel: ad1: cannot find label (no disk label)

Feb 23 14:01:40 /kernel: ad1s1: cannot find label (no disk label)

vms#


建立逻辑分区


vms# disklabel -e ad1s1


type: unknown

disk: amnesiac

label:

flags:

bytes/sector: 512

sectors/track: 63

tracks/cylinder: 16

sectors/cylinder: 1008

cylinders: 18931

sectors/unit: 19083393

rpm: 3600

interleave: 1

trackskew: 0

cylinderskew: 0

headswitch: 0 # milliseconds

track-to-track seek: 0 # milliseconds

drivedata: 0


8 partitions:

# size offset fstype [fsize bsize bps/cpg]

c: 19083393 0 unused 0 0 # (Cyl. 0 - 18931*)

e: 19083393 0 4.2BSD 4096 8192 16 # (Cyl. 0 - 18931*)


格式化分区，创建文件系统


vms# newfs /dev/ad1s1e

Warning: Block size and bytes per inode restrict cylinders per group to 67.

Warning: 3968 sector(s) in last cylinder unallocated

/dev/ad1s1e: 19083392 sectors in 4660 cylinders of 1 tracks, 4096 sectors

9318.1MB in 70 cyl groups (67 c/g, 134.00MB/g, 8512 i/g)

super-block backups (for fsck -b #) at:

32, 274464, 548896, 823328, 1097760, 1372192, 1646624, 1921056, 2195488, 2469920, 2744352, 3018784, 3293216, 3567648,

3842080, 4116512, 4390944, 4665376, ...


加载分区

vms# mkdir -p /disk1

vms# mount -t ufs /dev/ad1s1e /disk1
