XFS for Linux Pre-Release 0.10 New Features

XFS for Linux Pre-release 0.10 differs from Pre-release 0.9 in the following ways:

• Pre-release 0.10 is based on the Linux 2.4.2 kernel.
• Synchronous and direct I/O are now supported through the use of the O_SYNC and O_DIRECT file options.
• XFS 0.10 includes LVM 0.9.1 beta6 support. To use it you need the userland utilities from:

  ftp://ftp.sistina.com/pub/LVM/0.9.1_beta/lvm_0.9.1_beta6.tar.gz

  XFS 0.10 now supports MD RAID0, RAID1 and RAID5. RAID1 and RAID5 may perform slightly worse with XFS than with ext2. This will be addressed in a future release.

• mkfs.xfs will now attempt to make a qualified guess of the logsize depending on the size of the filesystem.

  On MD-based volumes, mkfs.xfs will automatically extract the stripe unit and stripe width.

• Major performance improvements have been made for the NFS write path, fixes to allow exporting XFS via the NFS V3 protocol have been made.
• Rebooting with an xfs root filesystem is now much faster than with XFS Pre-release 0.9.
• The XFS code has been resynced with the IRIX code base.
