solaris 10用SVM创建各种卷例子
本帖最后由 milujite 于 2011-11-24 15:15 编辑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。实验
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：
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 - 9 20.00MB (10/0/0) 40960
1 unassigned wm 10 - 1033 2.00GB (1024/0/0)4194304
2 backup wu 0 - 4091 7.99GB (4092/0/0) 16760832
3 unassigned wm 1034 - 2057 2.00GB (1024/0/0)4194304
4 unassigned wm 2058 - 3081 2.00GB (1024/0/0)4194304
5 unassigned wm 3082 - 4091 1.97GB (1010/0/0)4136960
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
8 boot wu 0 - 0 2.00MB (1/0/0) 4096
9 unassigned wm 0 0 (0/0/0) 0
metadb状态：
#metadb -a -c 2 -f c2t0d0s0 c3t0d0s0
#metadb -i
flags first blk block count
a u 16 8192 /dev/dsk/c2t0d0s0

a u 16 8192 /dev/dsk/c3t0d0s0
a u 8208 8192 /dev/dsk/c3t0d0s0
r - replica does not have device relocation information
o - replica active prior to last mddb configuration change
u - replica is up to date
l - locator for this replica was read successfully
c - replica's location was in /etc/lvm/mddb.cf
p - replica's location was patched in kernel
m - replica is master, this is replica selected as input
W - replica has device write errors
a - replica is active, commits are occurring to this replica
M - replica had problem with master blocks
D - replica had problem with data blocks
F - replica had format problems
S - replica is too small to hold current data base
R - replica had device read errors
创建raid0条带卷（即创建一个条带，串联里有两个组件）：
#metainit d0 1 2 c2t0d0s1 c3t0d0s1 -i 16k
#metaclearc2t0d0s1 c3t0d0s1
#metastat -p
d0 1 2 c2t0d0s1 c3t0d0s1 -i 32b
#ls -l /dev/md/*/d0
lrwxrwxrwx 1 root root 36 Nov6 17:29 /dev/md/dsk/d0 -> ../../../devices/pseudo/md@0:0,0,blk
lrwxrwxrwx 1 root root 36 Nov6 17:29 /dev/md/rdsk/d0 -> ../../../devices/pseudo/md@0:0,0,raw
创建raid0串联卷（即创建2个条带，每个串联里有一个组件）：
#metainit d0 2 1 c2t0d0s1 1 c3t0d0s1
d0: Concat/Stripe is setup
#metastat -p
d0 2 1 c2t0d0s1 \
1 c3t0d0s1
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）
#metainit d0 3 2 c2t0d0s1 c3t0d0s1 -i 64k 2 c2t0d0s3 c3t0d0s3 -i 32k 2 c2t0d0s5 c3t0d0s5 -i 16k
d0: Concat/Stripe is setup
#metastat -p
d0 3 2 c2t0d0s1 c3t0d0s1 -i 128b \
2 c2t0d0s3 c3t0d0s3 -i 64b \
2 c2t0d0s5 c3t0d0s5 -i 32b
通过raid0串联卷对普通分区文件系统扩容：
#newfs /dev/rdsk/c2t0d0s1
newfs: /dev/rdsk/c2t0d0s1 last mounted as /mnt
newfs: construct a new file system /dev/rdsk/c2t0d0s1: (y/n)? y

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！ 新手学习中！感谢楼主，有很大帮助 学习中，感谢楼主分享
