| Wouldn't it make more sense in today's situation to release the Tru64
| filesystem as GPLv3, to deal the with the software patent problem? As you
| know there is a new push from McCreevy to undermine Europe's position,
| there's an actual timeline of the European threat showing key junctions at
| the end of this summer.

HP to users: No need to worry about future of systems

| San Ho Yoon, who heads the information strategy team at Samsung Life, said
| the $25 million migration paid for itself in 18 months through reduced
| hardware, software and support costs. He added that he's pleased with the
| performance of Integrity and HP-UX, although he would have used Linux if it
| had scaled to 64 processors and been more reliable two years ago.

Btrfs 0.12, Performance Improvements
,----[ Quote ]
| Btrfs was first announced in June of 2007, as an alpha-quality filesystem
| offering checksumming of all files and metadata, extent based file storage,
| efficient packing of small files, dynamic inode allocation, writable
| snapshots, object level mirroring and striping, and fast offline filesystem
| checks, among other features. The project's website explains, "Linux has a
| wealth of filesystems to choose from, but we are facing a number of
| challenges with scaling to the large storage subsystems that are becoming
| common in today's data centers. Filesystems need to scale in their ability to
| address and manage large storage, and also in their ability to detect, repair
| and tolerate errors in the data stored on disk."

Btrfs Online Resizing, Ext3 Conversion, and More
,----[ Quote ]
| Chris Mason announced version 0.10 of his new Btrfs filesystem, listing the
| following new features, "explicit back references, online resizing (including
| shrinking), in place conversion from Ext3 to Btrfs, data=ordered support,
| mount options to disable data COW and checksumming, and barrier support for
| sata and IDE drives".

Linux: Btrfs, File Data and Metadata Checksums
,----[ Quote ]
| Chris Mason announced an early alpha release of his new Btrfs
| filesystem, "after the last FS summit, I started working on a new
| filesystem that maintains checksums of all file data and metadata." He
| listed the following features as "mostly implemented": "extent based file
| storage (2^64 max file size), space efficient packing of small files,
| space efficient indexed directories, dynamic inode allocation, writable
| snapshots, subvolumes (separate internal filesystem roots), checksums on
| data and metadata (multiple algorithms available), very fast offline
| filesystem check".

Interview: Chris Mason about Btrfs
,----[ Quote ]
| Q: Several people might be interested what you think about ZFS, why you see a
| need for Btrfs “despite of ZFS” (some people think ZFS is the solution for
| everything for them).
|
| Well, the short answer is that for Linux, there is no ZFS. I know about
| the FUSE port, but that isn’t a long term solution in terms of
| performance or enterprise workloads. ZFS has an impressive list of
| features (and clearly many happy users), but the real competition for
| Btrfs is other Linux filesystems.
