ReiserFS

今天伟大的 A core 说起我blog上面一个很严肃的问题，tag cloud似乎只是罗列了字母序的关键词，一看果然如此，还不完整，也许是 MT 系统要惩罚一下我最近的懒惰了？

说说最近的事情，流水帐。

一件折腾了很长时间的事是，公司的 filer 终于在 6 月 25 日那天寿终正寝。了却了一件心事，以后就准备一直用server去代替了，据说 NetApp 原来和我们公司是在一个院里起家的，不管是不是真的吧，这台 filer 也算是见证了相当长一段时间的历史，到最后连 EBay 上面都买不到它用的硬盘了。

总而言之，值得纪念的一天（顺手把UDP mount都改成TCP mount了）。

Hans Reiser的案子判了，15年，在最后关头他供出了埋老婆的地方，奇怪的美国法律，为什么这样可以从一级谋杀改判为二级谋杀？从新闻报道看，这个家伙很倒霉，被一个人差点骗走了公司，并且把老婆也抢了，然而杀人……之前以为美国警察逻辑混乱，现在看来，老婆失踪立刻把老公控制起来还是对的，十之八九跟那家伙有关。不过真是很可惜，ReiserFS恐怕从此走向死亡了，一个相当有成就，而且有了两个娃的技术专家，最后居然因为杀人而锒铛入狱，真是一件非常可惜的事情。现在人都怎么了？

昨天 康神 说 ReiserFS 网站没反应了，结果一上去发现还真是这样。他的两个 NS 服务器都给出了无 NS 记录的回应，看起来，不像是暂时的硬件故障。

So he has finally (after about six or more months) imported read-only ResierFS, congratulations, dumbbell, you have made a quite impressive change!

Since 6-ism VFS interface is quite different from 5-ism, so this change is not likely to be merged IMO. Read-write is also not likely to be available soon, but anyway, ReiserFS is a nice FS and supporting it is a good move.

Today another GPL kernel has problem with a 4TB RAID5 array, it thought that it is 2.1TB (on boot) and refuse to initialize it with its native file systems, including ReiserFS. On contrary, FreeBSD 5.4 and 6.0 works smoothly with a GENERIC kernel. Oh well…

Jean-Sébastien Pédron [jspedron club-internet.fr] has announced that he has ported ReiserFS 3.6 (from kernel 2.6.7) to FreeBSD (with only Read-Only support this time).

Scott Long suggests to import these to base because 6-CURRENT will have a focus on the file system. I suggested that we have a directory under somewhere in the src/ tree to keep these Linux bits so we can backport their fixes more easily and it should be better for us to rip these things out when we have re-written something from scratch.

Finally I am thinking about porting ReiserFS4 to FreeBSD. The current ReiserFS is GPL’ed so it should not get into FreeBSD kernel, but I think it might be OK to leave it as a ports of kernel module (like pf).
