Next round of xfs_repair(8) performance improvements (xfsprogs 2.9.2 onwards). It substantially improves the I/O performance compared to previous versions through the use of batch reads, background metadata prefetching and smart priority based libxfs caching. Lost+found behaviour has also been changed and will not re-orphan existing lost+found files.

Added new data allocator called "filestreams" to 2.6.22 kernels. It allows a directory to reserve an allocation group for exclusive use by files created within that directory. Files being written in other directories will not use the same allocation group and so files within different directories will not interleave extents on disk. The reservation is only active while files are being created and written into the directory. Filestreams can be enabled filesystem wide with a "-o filestreams" mount option, or on a per directory basis with an xfs_io(8) chattr flag.

| June-2007
|
Added a new tool, xfs_metadump(8), to capture the metadata of a corrupted filesystem for implementing improvements to xfs_repair(8).
|
| May-2007
|
Released "Lazy Superblock Counters" which significantly improves transaction intensive workloads which operate on the free space and inode usage counters in the superblock.
|
| March-2007
|
Fixed the notorious "NULL files" problem after a crash. The fix improves the syncronisation between updates of the file size and writes that extend a file.
|
| January-2007
|
Added [training/index.html XFS Training course] (still under development) and the documentation for the [papers/xfs_filesystem_structure.pdf XFS ondisk format].
|
| August-2006
|
Added the paper "High Bandwidth Filesystems on Large Systems" which was presented at the Ottawa Linux Symposium in July 2006.
|
| July-2006
|
Several bulkstat related performance improvements, mostly improving DMAPI scans for filesystems with many millions of inodes, but also generic readahead improvements that will help other bulkstat users (e.g. xfsdump and quota).
|
| July-2006
|
SLES10 is released, with full XFS and DMAPI support.
|
| June-2006
|
First round of xfs_repair(8) performance improvements, and buffer/inode caching now done in libxfs in preparation for a multi-threaded version of xfs_repair at a later date.
|
| May-2006
|
Additional inheritable inode flag (nodefrag) to allow specified inodes to be skipped by xfs_fsr(8).
|
| May-2006
|

|
| Mar-2006
|
Incore extent management rework, more efficiently using memory when working with files with large numbers of extents.
|
| Feb-2006
|
Per-CPU superblock accounting, improving buffered I/O throughput significantly for parallel I/O workloads.
|
| Dec-2005
|
Rework the page writeout code paths within XFS to make better use of advances in 2.6 kernels (page clustering and larger block I/O requests).
|
| Dec-2005
|
SLES9 Service Pack 3 released with next set of XFS updates.
|
| Nov-2005
|
Support for block layer write barriers, allowing devices to be used with their write cache enabled (2.6+ kernels).
|
| Nov-2005
|
Preferred extent size allocator hint for the B+ tree allocator.
|
| Sep-2005
|
Support for inline extended attribute format 2, which significantly improves performance when using extended attributes. Driven by needs of the Samba folks for Samba version 4, but also helpful to many other people.
|
| Jun-2005
|
Added support for project quota, and the ability to inherit project identifiers. Provides the mechanism for implementing a form of directory tree quota.
|
