以SUN Fire V880 Server(6*73GB Dsik)为例讲解在Solarsi8下使用命令行的方式安装及维护RAID1和RAID5。本文档内容都经本人实践验证过,但对于不同机型仅供参考。
Disk分布情况:
0:c1t0d0 1:c1t1d0 2:c1t2d0 3:c1t3d0 4:c1t4d0 5:c1t5d0
|
注:0,1做镜像;2,3,4,5做RAID5
系统盘(c1t0d0)分区及镜像盘(c1t1d0)情况:
c1t0d0s0(d10) d0 c1t1d0s0(d20) / 1024M c1t0d0s1(d11) d1 c1t1d0s1(d21) swap 8192M c1t0d0s2 c1t1d0s2 overlap 69999M c1t0d0s3(d13) d3 c1t1d0s3(d23) /usr 4096M c1t0d0s4(d14) d4 c1t1d0s4(d24) /opt 10240M c1t0d0s5(d15) d5 c1t1d0s5(d25) /var 2048M c1t0d0s6(d16) d6 c1t1d0s6(d26) /home free c1t0d0s7 c1t1d0s7 /metaDB 30M
|
系统安装完成后,使用Solarsi8 software 2 of 2安装DiskSuite_4.2.1软件,安装路径:/cdrom/cdrom0/Solaris_8/EA/installer & 选择默认安装就可以。
用root用户登陆,运行以下命令:
#prtvtoc /dev/rdsk/c1t0d0s2|fmthard –s – /dev/rdsk/c1t1d0s2 fmthard:New volume table of contents now in place
|
上面命令将第二块硬盘(c1t1d0)的文件分区表调整为和引导盘一致。
#umount /metaDB #rm –r /metaDB #vi /etc/vfstab
|
将下面这行注释掉或删除,如下:
#/dev/dsk/c1t0d0s7 /dev/rdsk/c1t0d0s7 /metaDB ufs 1 yes –
|
一、RAID1
对各个分区逐一作镜像:
①先生成replicas,这是DiskSuite内部用的。
#metadb –a –f –c 3 c1t0d0s7 c1t1d0s7 #metadb
|
②Creating a mirror from swap
#metainit –f d11 1 1 c1t0d0s1 #metainit d21 1 1 c1t1t0s1 #metainit d1 –m d11 #vi /etc/vfstab /dev/dsk/c1t0d0s1 - - swap – no – should be changed to: /dev/md/dsk/d1 - - swap – no - #reboot #metattach d1 d21
|
③Creating a mirror from /usr
#metainit –f d13 1 1 c1t0d0s3 #metainit d23 1 1 c1t1t0s3 #metainit d3 –m d13 #vi /etc/vfstab /dev/dsk/c1t0d0s3 /dev/rdsk/c1t0d0s3 /usr ufs 1 yes – should be changed to: /dev/md/dsk/d3 /dev/md/rdsk/d3 /usr ufs 1 yes – #reboot #metattach d3 d23
