Re: Reiser4. BEST FILESYSTEM EVER.
The reason why I ignore the tar+gzip tests is that in the past Hans has rigged the test by using a tar ball which was generated by unpacking a set of kernel sources on a reiser4 filesystem, and then repacking them using tar+gzip. The result was a tar file whose files were optimally laid out so that reiser4 could insert them into the filesystem b-tree without doing any extra work. I can't say for sure whether or not this set of benchmarks has done this (there's not enough information describing the benchmark setup), but the sad fact of the matter is that people trying to pitch Reiser4 have generated for themselves a reputation for using rigged benchmarks. Hans's used of a carefully stacked and ordered tar file (which is the same as stacking a deck of cards), and your repeated use of the bonnee++ benchmarks despite being told that it is a meaningless result given the fact that well, zero's compress very well and most people are interested in storing a file of all zeros, has caused me to look at any benchmarks cited by Reiser4 partisans with a very jaundiced and skeptical eye. Fortunately for you, it's not up to me whether or not Reiser4 makes it into the kernel. And if it works for you, hey, go wild. You can always patch it into your own kernel and encourage others to do the same with respect to getting it tested and adopted. My personal take on it is that Reiser3, Reiser4 and JFS suffer the same problems, which is to say they have a very small and limited development community, and this was referenced in Novell's decision to drop Reiser3: http://linux.wordpress.com/2006/09/27/suse-102-ditching-reiserfs-as-it-default-fs/ SuSE has deprecated Reiser3 *and* JFS, and I believe quite strongly it is the failure of the organizations to attract a diverse development community is ultimately what doomed them in the long term, both in terms of support as the kernel migrated and new feature support. It is for that reason that Hans' personality traits that tend to drive away those developers who would help them, beyond those that he hires, is what has been so self-destructive to Reiser4. Read the announcement Jeff Mahoney from SUSE Labs again; he pointed out was that reiser3 was getting dropped even though it performs better than ext3 in some scenarios. There are many other considerations, such as a filesystem's robustness in case on-disk corruption, long term maintenance as the kernel maintains, availability of developers to provide bug fixes, how well the system performs on systems with multiple cores/CPU's, etc. - Ted - To unsubscribe from this list: send the line unsubscribe linux-fsdevel in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

I hope that few on this list are not willing to conceed that Reiser4 is fast. Whether it is 10% slower than the best or 3 times as fast is probably not relevant to whether it gets included. All the worst case scenarious of Reiser4 performance and behavior should all still be sufficient to justify letting it in as Experimental. You can argue your benchmarks forever. Your benchmark has narrow applicability - pretty much every benchmark will. And all you do is provoke a firestorm of debate over whether compressing zeros means anything, whether compression is even a good idea, whether, .. The answer to ALL of these questions will be it depends I have dealt with huge data sets that were mostly zero's, a file system that had a factor of 3 space savings and or performance benefit might have mattered alot there - but they are not the norm.

Perhaps if you guided me through it. You deliberately ignored the fact that bad blocks are NOT dealt with by the filesystem,... but by the operating system. Like I said: If your filesystem is writing to bad blocks, then throw away your operating system. I may have missed something, but if my room-mate took my harddrive, screwed it open, wrote a love-letter on the disk with a pencil and then returned it (ok, there may be some more plausible reasons for corruption), is the OS really suppose to handle it? Yeah, I can't see how the OS could read the love-letter either. But one thing is for sure. The FS ain't responsible for reading it. Yes, it should not assign any new data to those blocks but should it not also fall into the file-systems domain to be able to restore some/all data? It's a tough ask of any FS. Microsoft's filesystem checker totally roasted all my data on an XP-box last night. I had used ntfsresize to reduce the partition size and had a power outage.
