			<content:encoded><![CDATA[<p>前幾日又被人追問點設定, 不幸地之前 DROP 下的NOTES 不見了. 結果今早在VM下由頭SET一次.</p>
<h3>1. Install related component</h3>
<pre class="brush:shell">conary update gcc gcc:devel
conary update libtool libtool:devel
conary update glib glib:devel
conary update glibc glibc:devel
conary update automake autoconf pkgconfig
conary update gcc-c++
conary update pam:devel
</pre>
<h3>2. Download &amp; extract proftpd (in this case 1.3.3 )</h3>
<pre class="brush:shell">wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.3.tar.gz

tar -zxf proftpd-1.3.3.tar.gz
cd proftpd-1.3.3
</pre>
<h3>3. Config &amp; Compile</h3>
<p>makesure proftpd ( ftp service ) stopped before &#8220;make install&#8221;.</p>
<pre class="brush:shell">./configure --prefix=/usr --sysconfdir=/etc/proftpd --localstatedir=/var/run --enable-nls --enable-auth-pam

make

make install
</pre>
<h3>4. modify generate.inc</h3>
<p>因為proftpd自1.3.2開始有一句config改了syntex, 所以openfiler要修改一下才能正常generate出1.32以後的proftpd.conf</p>
<p><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/03/1.-proftpd-fail-to-start.png" title="1. proftpd fail to start" rel="lightbox[532]" rel="lightbox[532]"><img class="alignnone size-medium wp-image-535" title="1. proftpd fail to start" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/03/1.-proftpd-fail-to-start-300x90.png" alt="" width="300" height="90" /></a></p>
<p>Modify openfiler web generate.inc</p>
<pre class="brush:shell">vi ./opt/openfiler/var/www/includes/generate.inc
</pre>
<p>find</p>
<p>$ac_ftp_fp-&gt;AddLine(&#8220;DisplayFirstChdir\t\t.message&#8221;);</p>
<p>replace with</p>
<p>$ac_ftp_fp-&gt;AddLine(&#8220;DisplayChdir\t\t.message&#8221;);</p>
<p>修改完後到share edit 再 update 令openfiler更新一次proftpd.conf</p>
<p><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/03/2.-update-share-setting.png" title="2. update share setting" rel="lightbox[532]" rel="lightbox[532]"><img class="alignnone size-medium wp-image-536" title="2. update share setting" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/03/2.-update-share-setting-300x219.png" alt="" width="300" height="219" /></a></p>
<p>這樣就可以start ftp service.</p>
<p>1.3.3 已解決MLST不能正常進入有&#8221;[]&#8220;的路徑問題. 所以不用disable mod-facts</p>
<p>關於1.3.2 的問題和解決方法.</p>
<p><a href="http://forum.filezilla-project.org/viewtopic.php?f=2&amp;t=13555" target="_blank">FileZilla Forums • View topic &#8211; 550 error on certain characters</a></p>

<p>再找Samba個Changes log發現以下幾點</p>
<ol>
<li>Samba 3.45 只用SMB v1, 而Vista 、Server 2008 &amp; Windows 7 用SMB v2</li>
<li>Microsoft 話 SMB v2 快過 SMB v1</li>
<li>SMB v1 訊息最大64KB, 同TCP Windows Size 個Concept 一樣, 即是TCP Windows size max = 64KB,<br />
相對現在Linux Kernel 可以設定大過16MB相差很遠</li>
<li>Samba 3.5 會加入 SMB v2.</li>
</ol>
<p>可能等到Samba 3.5 release 才知能否突破這個限制</p>

		<description><![CDATA[農歷新年幾日足不出戶，重點完成了家裏NAS PROJECT (除了NAS 還睇完100集REBORN)
因為有兩隻1TB是有DATA的，所以花了多了時間。
一晚時間做 BACKUP、一日安裝、兩日個調整，終於大功告成。
硬件

ASL ATOM 330 ITX
onboard  ICH7 with 4x SATA、1&#215;40PIN PATA,
PCIE x16 slot (x8 Actual)
Realtek 8111C Gigabit Ethernet
AC97 (no use for me)
1GB DDR2
4GB CF BOOT UP

		<description><![CDATA[以下是測試Openfiler  Software RAID 5 擴展的過程
環景是Vmware ESXi, 由6隻Virtual Disk的RAID5擴展到7碟

先是檢視現有的RAID,
/sbin/mdadm &#8211;detail /dev/md0

在VM加多一隻SCSI DISK後, 做一次SCSI Rescan 令到新碟顯示

把新碟初始化
parted /dev/sdh
mklabel msdos
mkpart primary ext2 0 8192
set 1 raid on
quit
並把新碟加入RAID
mdadm &#8211;add /dev/md0 /dev/sdh1

把RAID由6碟擴展為7碟
mdadm &#8211;grow /dev/md0 &#8211;raid-devices=7

在背景碟擴佔用CPU不多


完成RAID

到Physical Volume

再擴大Logical Volume

最後到XFS
