solaris 10用SVM创建各种卷例子

milujite

其实官方中文文档都有的～最近看卷的帖子比较多，自己刚好前几天做了下实验，分析给大家吧。

1. 实验
   
2. 有两个磁盘c2t0d0和c3t0d0。两个盘的s0都分配20mb大小，用于存放2个metadb，并且分区表如下：
   
3. Part      Tag    Flag     Cylinders        Size            Blocks
   
4.   0 unassigned    wm       0 -    9       20.00MB    (10/0/0)      40960
   
5.   1 unassigned    wm      10 - 1033        2.00GB    (1024/0/0)  4194304
   
6.   2     backup    wu       0 - 4091        7.99GB    (4092/0/0) 16760832
   
7.   3 unassigned    wm    1034 - 2057        2.00GB    (1024/0/0)  4194304
   
8.   4 unassigned    wm    2058 - 3081        2.00GB    (1024/0/0)  4194304
   
9.   5 unassigned    wm    3082 - 4091        1.97GB    (1010/0/0)  4136960
   
10.   6 unassigned    wm       0               0         (0/0/0)           0
    
11.   7 unassigned    wm       0               0         (0/0/0)           0
    
12.   8       boot    wu       0 -    0        2.00MB    (1/0/0)        4096
    
13.   9 unassigned    wm       0               0         (0/0/0)           0
    
14. 
    
15. metadb状态：
    
16. [root@Solaris /]#metadb -a -c 2 -f c2t0d0s0 c3t0d0s0
    
17. [root@Solaris /]#metadb -i
    
18.         flags           first blk       block count
    
19.      a        u         16              8192            /dev/dsk/c2t0d0s0
    
20.      a        u         8208            8192            /dev/dsk/c2t0d0s0
    
21.      a        u         16              8192            /dev/dsk/c3t0d0s0
    
22.      a        u         8208            8192            /dev/dsk/c3t0d0s0
    
23. r - replica does not have device relocation information
    
24. o - replica active prior to last mddb configuration change
    
25. u - replica is up to date
    
26. l - locator for this replica was read successfully
    
27. c - replica's location was in /etc/lvm/mddb.cf
    
28. p - replica's location was patched in kernel
    
29. m - replica is master, this is replica selected as input
    
30. W - replica has device write errors
    
31. a - replica is active, commits are occurring to this replica
    
32. M - replica had problem with master blocks
    
33. D - replica had problem with data blocks
    
34. F - replica had format problems
    
35. S - replica is too small to hold current data base
    
36. R - replica had device read errors
    
37. 
    
38. 创建raid0条带卷（即创建一个条带，串联里有两个组件）：
    
39. [root@Solaris /]#metainit d0 1 2 c2t0d0s1 c3t0d0s1 -i 16k
    
40. [root@Solaris /]#metaclear  c2t0d0s1 c3t0d0s1
    
41. [root@Solaris /]#metastat -p
    
42. d0 1 2 c2t0d0s1 c3t0d0s1 -i 32b
    
43. [root@Solaris /]#ls -l /dev/md/*/d0
    
44. lrwxrwxrwx   1 root     root   36 Nov  6 17:29 /dev/md/dsk/d0 -> ../../../devices/pseudo/md@0:0,0,blk
    
45. lrwxrwxrwx   1 root     root   36 Nov  6 17:29 /dev/md/rdsk/d0 -> ../../../devices/pseudo/md@0:0,0,raw
    
46. 
    
47. 创建raid0串联卷（即创建2个条带，每个串联里有一个组件）：
    
48. [root@Solaris /]#metainit d0 2 1 c2t0d0s1 1 c3t0d0s1
    
49. d0: Concat/Stripe is setup
    
50. [root@Solaris /]#metastat -p
    
51. d0 2 1 c2t0d0s1 \
    
52.          1 c3t0d0s1
    
53. 
    
54. 创建raid0条带串联卷每个条带使用不同的交错大小（3个条带，每个串联里有2个组件，并且使用不同的交错大小）
    
55. [root@Solaris /]#metainit d0 3 2 c2t0d0s1 c3t0d0s1 -i 64k 2 c2t0d0s3 c3t0d0s3 -i 32k 2 c2t0d0s5 c3t0d0s5 -i 16k
    
56. d0: Concat/Stripe is setup
    
57. [root@Solaris /]#metastat -p
    
58. d0 3 2 c2t0d0s1 c3t0d0s1 -i 128b \
    
59.          2 c2t0d0s3 c3t0d0s3 -i 64b \
    
60.          2 c2t0d0s5 c3t0d0s5 -i 32b
    
61. 
    
62. 通过raid0串联卷对普通分区文件系统扩容：
    
63. [root@Solaris /]#newfs /dev/rdsk/c2t0d0s1
    
64. newfs: /dev/rdsk/c2t0d0s1 last mounted as /mnt
    
65. newfs: construct a new file system /dev/rdsk/c2t0d0s1: (y/n)? y
    
66. Warning: 2048 sector(s) in last cylinder unallocated
    
67. /dev/rdsk/c2t0d0s1:     4194304 sectors in 683 cylinders of 48 tracks, 128 sectors
    
68.         2048.0MB in 43 cyl groups (16 c/g, 48.00MB/g, 11648 i/g)
    
69. super-block backups (for fsck -F ufs -o b=#) at:

SVM还行啊，跟AIX的VM比那确实是差了。不过都差不多～好在SOLARIS还有ZFS～

补充：raid1卷扩容
如果d10已经被挂载在/files下，还需要
growfs -M /files /dev/md/rdsk/d0
来扩展文件系统。
要不然即使metastat里看到d0扩展了，但df -h看到的/dev/md/rdsk/d0还是原始大小。
亲测！
