ZFS boot disk 更換成較大容量的硬碟
在有些時候我們需要更換開機硬碟，或是既有硬碟容量太小，欲更換成較大的硬碟，ZFS 與過去UFS的做法有些不同，UFS常用的方法為ufsdump 跟ufsrestore方式，而ZFS使用mirror操作，更為快速及方便。
使用設備Oracle SPARC T3-2，開機硬碟為146GB硬碟，欲改成300GB硬碟
檢視目前機器內的硬碟：

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
# 輸入 root 的密碼，如果沒有設定過，直接按 Enter 鍵即可
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
# 是否設定 root 的密碼
Set root password? [Y/n] y
New password: abc123
Re-enter new password: abc123

Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
# 移除 anonymous 使用者
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
# 是否取消 root 遠端登入

... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
# 是否移除 test 資料表

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
# 是否重新載入資料表權限

All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

建議設定:
To enforce this setting, use the command:
# auditconfig -conf
# auditconfig -setflags lo,ad,ft,ex
# auditconfig -setnaflags lo
# auditconfig -setpolicy cnt,argv,zonename
# auditconfig -setplugin audit_binfile active p_minfree=1
# audit -s
auditconfig -setpolicy cnt,argv,zonename
# rolemod -K audit_flags=lo,ad,ft,ex:no root
PS. 為避免audit log過大難以讀取，設定每小時將目前的audit log關掉，並開啟一個新的audit log檔
# EDITOR=ed crontab -e root << END_CRON
$
