标题: 命令行创建RAID5(非常感谢前人的工作!)
1.建立分区表
partition> p
Current partition table (original):
Total disk cylinders available: 4924 + 2 (reserved cylinders)

Part    Tag Flag    Cylinders       Size          Blocks
  0 unassigned wm    18 - 4690       8.00GB (4673/0/0) 16780743
  1 unassigned wu    0             0       (0/0/0)          0
  2 unassigned wm    0             0       (0/0/0)          0
  3 unassigned wm    0             0       (0/0/0)          0
  4 unassigned wm    0             0       (0/0/0)          0
  5 unassigned wm    0             0       (0/0/0)          0
  6 unassigned wm    0             0       (0/0/0)          0
  7 unassigned wm    0 - 17    31.56MB (18/0/0)    64638

2.传送分区表参数到其他硬盘
prtvtoc /dev/rdsk/c0t0d0s0|fmthard -s- /dev/rdsk/c0t1d0s0
prtvtoc /dev/rdsk/c0t0d0s0|fmthard -s- /dev/rdsk/c0t2d0s0
prtvtoc /dev/rdsk/c0t0d0s0|fmthard -s- /dev/rdsk/c0t3d0s0
prtvtoc /dev/rdsk/c0t0d0s0|fmthard -s- /dev/rdsk/c0t4d0s0
prtvtoc /dev/rdsk/c0t0d0s0|fmthard -s- /dev/rdsk/c0t5d0s0

3.建立metadb
metadb -a -f -c 3 c0t0d0s7 c0t1d0s7 c0t2d0s7

4.建立raid5(5 disks)
metainit d10 -r c0t0d0s0 c0t1d0s0 c0t2d0s0 c0t3d0s0 c0t4d0s0

5.建立HSP
metainit hsp001 c0t5d0s0

6.增加HSP到raid
metaparam -h hsp001 d10

7.验证
# metastat
d10: RAID
State: Initializing
Initialization in progress: 31.8% done
Hot spare pool: hsp001
Interlace: 32 blocks
Size: 67119381 blocks (32 GB)
Original device:
Size: 67121536 blocks (32 GB)
      Device    Start Block  Dbase       State Reloc  Hot Spare
      c0t0d0s0       330       No Initializing Yes
      c0t1d0s0       330       No Initializing Yes
      c0t2d0s0       330       No Initializing Yes
      c0t3d0s0       330       No Initializing Yes
      c0t4d0s0       330       No Initializing Yes

hsp001: 1 hot spare
      Device    Status    Length Reloc
      c0t5d0s0 Available 16780743 blocks Yes

Device Relocation Information:
Device Reloc  Device ID
c0t5d0 Yes id1,ssd@w20000020370984af
c0t0d0 Yes id1,ssd@w2000002037146e50
c0t1d0 Yes id1,ssd@w2000002037146b7e
c0t2d0 Yes id1,ssd@w2000002037146dff
c0t3d0 Yes id1,ssd@w2000002037146c22
c0t4d0 Yes id1,ssd@w20000020370d7dc5

8.投入使用
#newfs /dev/md/rdsk/d10
newfs: construct a new file system /dev/md/rdsk/d10: (y/n)? y
Warning: 1 sector(s) in last cylinder unallocated
/dev/md/rdsk/d10:    67119380 sectors in 18691 cylinders of 27 tracks, 133 sectors
      32773.1MB in 1169 cyl groups (16 c/g, 28.05MB/g, 3392 i/g)
super-block backups (for fsck -F ufs -o b=#) at:
32, 57632, 115232, 172832, 230432, 288032, 345632, 403232, 460832, 518432,
Initializing cylinder groups:
.......................
super-block backups for last 10 cylinder groups at:
66592544, 66650144, 66707744, 66765344, 66822944, 66880544, 66938144,
66995744, 67053344, 67110944,
#mkdir /raid5
#vi /etc/vfstab
添加一行:
/dev/md/dsk/d10 /dev/md/rdsk/d10 /raid5 ufs 2 yes -
#reboot(OR mount /dev/md/dsk/d10 /raid5)

9.维护RAID5(未测试)
坏掉一个盘的恢复方法(例c0t1d0盘坏掉)
ok boot -r
#metareplace -e d10 c0t1d0s0
#metastat d10
10.操作环境
1)硬件Sun E3000 + A5200
2)系统Solaris 9
