给/USR做软RAID，搞出问题，4900机器

[weixin_38050602]

c0t3d0s6是我的USR分区

# metainit -f d12 1 1 c0t3d0s6
d12: Concat/Stripe is setup
# metainit d22 1 1 c1t0d0s6
d22: Concat/Stripe is setup
# metainit d2 -m d12
d2: Mirror is setup
（编辑/etc/vfstab 文件使/usr 引用该镜像）
从/dev/dsk/c0t3d0s6 /dev/rdsk/c0t3d0s6 /usr ufs 1 yes -改成
/dev/md/dsk/d2 /dev/md/rdsk/d2 /usr ufs 1 yes -

# reboot
然后准备做 # metattach d2 d22


但是系统无法启动，出现大量的这个信息
