1. 以超级用户身份登陆或su
   
   
2. 创建zone
   # zonecfg -z centos
   centos: No such zone configured
   Use 'create' to begin configuring a new zone.
   zonecfg:centos>  create -t SUNWlx
   zonecfg:centos> set zonepath=/export/centos_root
   zonecfg:centos> add net
   zonecfg:centos:net> set address=192.168.0.2/24
   zonecfg:centos:net> set physical=e1000g0
   zonecfg:centos:net> end
   zonecfg:centos> commit
   zonecfg:centos> exit
   
   
3. 安装lx zone
   
   • 从OpenSolaris网站上下载CentOS Linux。
     
     
   • 以下载的tar包为源安装CentOS
     # zoneadm -z centos install -d /export/centos_fs_image.tar
     A ZFS file system has been created for this zone.
     Installing zone 'centos' at root directory '/export/centos_root'
     from archive '/export/centos_fs_image.tar'
     
     This process may take several minutes.
     
     Setting up the initial lx brand environment.
     System configuration modifications complete.
     Setting up the initial lx brand environment.
     System configuration modifications complete.
     
     Installation of zone 'centos' completed successfully.
     
     Details saved to log file:
         "/export/centos_root/root/var/log/centos.install.9025.log"
     
     
4. 检查安装后zone的状态
   # zoneadm list -iv
     ID NAME             STATUS     PATH                           BRAND    IP   
      0 global           running    /                              native   shared
      - centos           installed  /export/centos_root            lx       shared
   
   
5. 启动安装好的zone
   # zoneadm -z centos boot
   chichi# zoneadm list -iv
     ID NAME             STATUS     PATH                           BRAND    IP   
      0 global           running    /                              native   shared
      9 centos           running    /export/centos_root            lx       shared
   
   
6. Login
   # zlogin centos
   
   要运行X应用程序的话，用ssh进行X输出重定向
   # ssh -X centos
   
   
7. 和网络配置相关的设置
   
   • 设置DNS
     

     $ cat /etc/sysconfig/network
     NETWORKING=yes
     HOSTNAME=centos
     GATEWAY=192.168.0.1
     $ cat /etc/resolv.conf
     nameserver 192.168.0.1
     
     

8. 安装附加软件包
   # yum install libstdc++

I installed Solaris Developer Release 1/08 on my machine and tried with ZFS. I have to say that I was impressed by the powerful functionality and easy usage model of ZFS. I used to maintain a website server which is based on LAMP. Now I would take SAMP + ZFS as a better solution. In SDR 1/08, Web Stack Admin provides easy access to Apache2, MySQL and PHP, while ZFS shows immense scalability, great data integrity and simple administration. SAMP would be another topic. Here I just want to focus on how to start using ZFS.

After installation, the default root system is UFS. ZFS boot is still in work. I converted Solaris slice c0d0s7, which is mounted on /export to ZFS. Before creating zfs pools, remove "/dev/dsk/c0d0s4 ..." entry from /etc/vfstab and unmount it.

# umount /export

Now create a ZFS pool.

# zpool create zfs_export c0d0s7

invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c0d0s7 contains a ufs filesystem.

The command failed because the slice contained a ufs filesystem. Add -f option to zpool create command.

# zpool create -f zfs_export c0d0s7
# zpool list

NAME         SIZE   USED  AVAIL    CAP  HEALTH  ALTROOT
zfs_export  66.5G   111K  66.5G     0%  ONLINE  -

Change mount point to /export.

# zfs set mountpoint=/export zfs_export
# zfs list
NAME           USED  AVAIL  REFER  MOUNTPOINT
zfs_export     117K  65.5G    18K  /export

Share /export via NFS as read/write.

# zfs set sharenfs=on zfs_export
# share

zfs_export@zfs  /export   rw   ""

Share /export via SMB.

# svcadm enable -r smb/server
   
svcadm: svc:/milestone/network depends on svc:/network/physical, which has multiple instances.
# svcs | grep smb
online         13:28:03 svc:/network/smb/server:default
# zfs set sharesmb=on zfs_export
# zfs set sharesmb=name=myshare zfs_export
i# sharemgr show -vp                      

default smb=() nfs=()
zfs
    zfs/zfs_export nfs=()
          /export
                  myshare=/export
                  zfs_export=/export

Recover 'rm' ed files?

AFAIK, the answer is noway.

Make zfs root filesystem and boot from it?

1. 什么是SpeedStep

为了延 长笔记本电脑上电池的使用寿命，Intel的CPU采用了称为SpeedStep的技术，SpeedStep技术动态改变CPU的倍频以降低其工作频率， 甚至降低核心电压。这样当CPU工作在较低频率时，就可以节省耗电量，减小发热，以及降低风扇噪音。起初支持SpeedStep技术的CPU有两种工作模 式，一种是外接交流电，CPU工作在较高频率的最优性能模式（maximum performance mode）；另一种是用电池供电，CPU的工作在较低频率的电池优化模式（battery-optimized mode）。笔记本根据外接电源自动选择工作模式。随后，Intel发布了增强的SpeedStep技术（Enhanced SpeedStep），系统根据当前负载自动改变CPU的频率和核心电压。在此基础上，Intel进一步增强了SpeedStep技术（Enhanced Improved SpeedStep），CPU支持多种工作频率和核心电压，在两种基本工作模式之间增加了多种中间模式，系统根据当前负载自动切换CPU的工作模式。

2. Solaris上配置SpeedStep

OpenSolaris Express/Developer Edition支持Enhanced SpeedStep技术。其支持的Intel CPU包括

• Pentium 4和Intel Xeon处理器
  
• Intel Core Solo和Intel Core Duo处理器
  
• Intel Xeon Processor 5100系列和Intel Core 2 Duo处理器
  

$ kstat -m cpu_info -s supported_frequencies_Hz

• 越界访问
• 访问未被初始化的数据
• 访问已被释放的内存

 本文介绍如何利用mdb的::findleaks检测内核代码的内存泄漏。

本文将以一个驱动程序（tleak.c tleak.conf）为例说明如何利用mdb的::findleaks命令检测内核代码是否存在内存泄漏。

请 注意，上一篇文章给的示例应用程序其内存泄漏发生在堆（heap）上，当程序退出的时候，堆随之被释放掉，所以并不会对系统造成影响。而本文提供的示例驱 动tleak将在内核产生内存泄漏，所以请谨慎使用，不熟悉内核的朋友请不要在自己的机器上运行该驱动及以下步骤。（USE AT YOUR OWN RISK）

tleak是一个伪字符设备，每打开一次，会进行一次内存分配，则当第二次打开该设备的时候就会产生内存泄漏，主要函数tleak_open()定义如下：
