FreeBSD

After several months’ work, we have finally get the Handbook into shape, and currently only the MAC and NETWORK-SERVER chapters are partially translated. All chapters are now in sync with English revision.

Review comments are highly appreciated.

Cameron Grant, author of the newpcm driver, died this morning. May he rest in peace.

As title. We *need* to struggle to make the upcoming 6.0-RELEASE a good release . I hope we can show the great improvements taken place in 6-CURRENT and hopefully we can cut 6-STABLE this June.

Highlights on recent 6-CURRENT that was not merged (and may never be merged):

• MPSAFE VFS
• Integrated VFS hashing (generallized, traditionally it’s different on ufs, msdosfs, etc)
• 64bit-ize of several utilities, to ensure better usage of large storage.

And finally, it happend.

On Monday, one of our server, running FreeBSD, panic’ed with “ffs_clusteralloc: map mismatch”. This message is quite uncommon and should only happen when there is some “event” with the memory or hard disk.

I have suggested our administrator to reboot and do “fsck” on the volume, since it has very small block size and can not be checked background (I have made a change to warn about this to FreeBSD, and was MFC’ed to 5-STABLE so you will get the feature in 5.4-RELEASE). Unfortunatelly, the check is so slow and we start to suspect whether there is some hardware problem.

A GPL’ed (say, it’s not OpenSource, but the source code is available publicly) PHP accelerator has been evaluated at lab, which is called eAccelerator. I should adjust my claim that this sort of application is not useful.

During my test, the accelerator has improved the TPS by about 50%, and is quite impressive.

In order to install this on FreeBSd, you should have installed PHP from ports, and go to www/eaccelerator and ``make install’'.

If there is single advocacy stuff have seen in any Chinese BSD forum, no matter which, if I saw, I will not shut up for the following week. Stop cheating, and I shut up, if you continue cheating, I won’t, and moreover, I promise to use your evidence to prove that you are lying. Shut up, and that’s not a unilateral action, mmmkay?

With FreeBSD, we have a stress test tool called “make universe”.

This will stress test your RAM, I/O, and CPU.

Then I found that my new system have defect RAM :-(

最近 Bruce A. Mah[暂时还不清楚他的中文名字] 和 佐藤 広生(Hiroki Sato) 两个人在为 FreeBSD 5.4-RELEASE 的 Release Notes 做大量的前期准备。我注意到我所做的许多改进都被作为比较重要的变化写进了 Release Notes，感觉很有成就感。

They did it again!

Before patching your already fragile kernel, consider other true Open Source operating systems, like FreeBSD and DragonFlyBSD!

Someone has disclosed that he is implementing iSCSI on FreeBSD, at scsi@. iSCSI is essential technology that is highly scalable and looks quite promising.
