	ReiserFS - Wikipedia, the free encyclopedia
		The ReiserFS is a general-purpose computer file system designed and implemented by a team at Namesys led by Hans Reiser, who is referred to as the project's Benevolent Dictator for Life.
		ReiserFS is the default filesystem on the Slackware, SuSE, Xandros, Yoper, Linspire, Kurumin Linux, FTOSX and Libranet Linux distributions.
		ReiserFS stores file metadata ("stat items"), directory entries ("directory items"), inode block lists ("indirect items") and tails of files ("direct items") in a single, combined B+ tree keyed by a universal object id. Disk blocks allocated to nodes of the tree are "formatted internal blocks".

	Linux PR: Journaling FS Ships For Gnu/Linux Today
		Journaling for ReiserFS has officially been released by Namesys after extensive testing, and confirmation of its stability by betatesters.
		ReiserFS is a revolutionary new approach to file system design which stores not just filenames but the files themselves in a B*-tree, giving it performance advantages throughout the file size spectrum.
		We had thought that surely it would take another 6 months of refinement before we could throw away the non-journaling code without making speed lovers unhappy, but his first version is already faster than the non-journaling code, plus you don't have to wait for fsck everytime you kick a powercord.

	The structure of the Reiser file system
		Reiserfs tries to assign items whose key values lie closely together block numbers that are also close together, but this does not matter for the description of the structural layout.
		However, reiserfs journals entire disk blocks as they have to appear in the file system after the journal transaction is committed.
		As the keys in reiserfs are sorted by parent directory ID first, items that are in the same directory are grouped together in the file system tree.

	Common threads: Advanced filesystem implementor's guide, Part 1
		ReiserFS 3.6.x (the version included as part of Linux 2.4) is designed and developed by Hans Reiser and his team of developers at Namesys.
		ReiserFS uses a specially optimized b* balanced tree (one per filesystem) to organize all filesystem data.
		In order to increase performance, ReiserFS is able to store files inside the b*tree leaf nodes themselves, rather than storing the data somewhere else on the disk and pointing to it.

		ReiserFS avoids this by never allocating a data block until there is no chance a log replay will overwrite the contents with old information.
		LVM 0.9 and ReiserFS 3.6.18 have this functionality, but we are not sure when the generic calls are going to be added in the kernel.
		ReiserFS has problems supporting NFS because 64 bits of information are required to find an object in the tree, and NFS expects to find an inode with just the inode number (32-bits long).

	Common threads: Advanced filesystem implementor's guide, Part 2
		In ReiserFS lingo, "tails" are files that are smaller than a filesystem block (4k) or the trailing portions of files that don't quite fill up a complete filesystem block.
		ReiserFS has really excellent small-file performance because it is able to incorporate these tails into its btree (its primary organizational data structure) so that they are really close to the stat-data (ReiserFS*' equivalent of an i-node).
		Fortunately, the ReiserFS guys anticipated that some people would be willing to sacrifice around 5% of their disk capacity for a little extra performance, so they created the "notail" mount option.

	BULMA: Journal File Systems in Linux
		ReiserFS has an excellent small-file performance because it is able to incorporate these tails into its B-Tree so that they are really close to the stat data.
		ReiserFS uses fixed size block (4KB) oriented allocation that affects negatively to the performance of I/O operations of large files.
		The other weakness of ReiserFS is that the sparse file performance is significantly worse compared to ext2, although Namesys is working on optimising this case.

	freshmeat.net: Project details for reiserfs
		reiserfs is a revolutionary new approach to file system design which stores not just filenames but the files themselves in a B*-tree.
		Reiserfs doesn't suffer from log congestion either, you can effectively use it for quickly creating a 100,000 entry directory, and it is fairly unique in that.
		Personaly I am not a big fan of journals, it happen so rarely that the computer crash or a power outage occur that I don't really need it (could be important for people who need to reboot quickly after a problem however).

		V3 of reiserfs is used as the default filesystem for SuSE, Lindows, FTOSX, Libranet, Xandros and Yoper.
		V3 of reiserfs offers both meta-data and data journaling, and defaults to meta-data journaling because that is the right solution for most users.
		Previous versions of reiserfs (3.5 and 3.6) used "generation counter" to overcome this problem: keys for file names having the same hash value were distinguished by having different generation counters.

		"[ReiserFS] is the default filesystem for all SuSE installs, so we dedicate significant resources to ReiserFS stability, performance and features," Joseph Eckert, spokesperson for SuSE Linux, told NewsFactor.
		"ReiserFS performs well, is well-maintained, and the developers leverage advanced filesystem research while keeping an eye on the feature set we want," said Cheryl Schwarzman, a spokesperson for Lindows.com.
		Version 4 of ReiserFS is architected to keep data substantially more secure than v3 due to its use of atomic operations and a better designed fsck (file system check), Reiser said.

		Therefore, the filesystem is repaired (brought to a consistent state) very quickly, no matter how big the drive is! In addition to how filesystems write/read the data to and from the disk, the manner in which filesystems utilize journaling makes them different from one another.
		ReiserFS, alternatively, stores these files in the B*tree leaf nodes instead of writing the address of the data in the nodes and the files on the disk like all other files.
		It's speed was very close to that of ReiserFS when handling medium to small files, unless certain optimizing parameters are passed during the creation and mounting of the filesystem.

	ITworld.com - Tips on reiserfs
		Reiserfs is a journaling file system that is purportedly more efficient at handling many small files than the de facto standard ext2fs file system and just as efficient as ext2fs in other cases.
		What I like most about reiserfs is that it recovers from things such as power failures extremely fast, since it doesn't have to perform the lengthy consistency checks required by ext2fs.
		I have reiserfs configured as a loadable module, since that makes it easier to fix any potential reiserfs problems in the future without having to recompile the whole kernel.

		ReiserFS doesn't have as much of a problem with that as ext2/3 does.
		ReiserFS has shown it does work a lot faster in benchmarks with tons of smaller files like your going to get with maildir.
		ReiserFS seems to have a lot of disappointed users from broken filesystems (I've heard a lot of comments about fsck.reiser making people's partitions un-recoverable).

		ReiserFS is a new FileSystem for Linux developed by HansReiser at a company he owns.
		Unfortunately, the tree structure used is also the weak point of ReiserFS: if any of it gets corrupted, chances are that much more data will be affected than under traditional FileSystems.
		Rather than losing a single file to corruption of an inode, you may lose almost the entire contents of your disk if metadata close to the root of the BTree is affected.

		Step by step, /, /usr (with "-t reiserfs") and /boot (with "-t ext2") were mount ed on /mnt and the files where copied with "cp" or with a pipe with "tar", into the new partition.
		Meanwhile, ReiserFS has been running for quite a month on my system and until no w, the results are very satisfying.
		...for reiserfs: First, there is ext3 as a logical successor of the current ext2 file-system, that is in early alpha stage according to the developers and so cannot be used in a "productive" environment.

		ReiserFS partitions will appear as additional disks to the Windows operating system, allowing files on ReiserFS partitions to be transparently accessed from any Windows application.
		Linux's interface to ReiserFS will be studied and documented in contrast to the IFSD interface required by Windows.
		The ReiserFS code from GRUB will be studied as a light-weight C implementation of read-only ReiserFS functionality, which may be important in porting ReiserFS to Windows.

	[NCLUG] ext3 versus ReiserFS? (Site not responding. Last check: 2007-10-08)
		One thing that makes me a bit skiddish about installing ReiserFS is I've seen a number of posts on the kernel mailing list (and granted, this was awhile ago when I was actively reading Kernel Traffic) where Hans Reiser would post a message to the effect of "Oops...
		To install this patch, you have to reformat." For awhile, the ReiserFS folks were mucking around all the time with the superblock format (or whatever Reiser calls it)...
		I do know that Mandrake has been shipping with Reiser for some time now, and I have a friend here in SLO that has been using it on his workstation for a long time now (ca.

	Interview With the People Behind JFS, ReiserFS & XFS - OSNews.com
		Stability is not the issue, ReiserFS is known to be stable by the people who use it.
		ReiserFS does a complete tree traversal for every 4k block it writes, and then it inserts one pointer at a time into the tree, which means that every 4k write incurs the overhead of a balancing of the tree (which means it moves data around.
		XFS is slower than reiserfs for the typical file size distributions on "typical" file systems, and I encourage you to examine our benchmarks, where you will see that they are faster for very large file writes, and slower for typical file sizes.

		All ReiserFS data is organized in blocks, and each block has this size (in bytes).

		Accordingly, people favouring ReiserFS or XFS on commodity PC hardware should think long and hard before using those with data they care about — absent uninterruptable power supplies.
		This means that if you modify the mod time of an inode, instead of writing the entire inode table block to the journal, they just write a note in the journal stating that "inode X now has a mod time of Y".
		The practical upshot of this is that if you use XFS or ReiserFS, and you are on crappy PC-class hardware, you *MUST* have a UPS, and use a serial/USB cable, so that system can do a graceful shutdown when the UPS's batteries are exhausted.

		Remember that even though you may be transferring large movies every once in a while, most of the operating system is small files.
		reiserfs does just fine with large files, but it's more tailored to small files, so it's optomized for them.
