IRIX 6.5.29 Highlights
SGI Software Product Life Cycle Management
- New xfs_quota command
IRIX 6.5.29 includes a new xfs_quota command that allows you to manage the use of quotas on an XFS filesystem.
- New extsize option for xfs_io command
The xfs_io command includes an extsize option that allows you to display and/or modify the preferred extent size used when allocating space for the currently open file.
- rpc.mount no longer reports nohide entries
rpc.mount does not report exported entries marked as nohide if they correspond to the root of the mounted filesystem. To return to the behavior of earlier releases, use the -C option to rpc.mountd. The exportfs command will check whether the nohide option is used to export a directory that is not a root of a filesystem and issue a warning; the option will be ignored.
- Ability to store inode's parents in xfs filesystem added
The mkfs_xfs command includes a parent= option that allows you to specify that links to the inode's parents and associated directory entry names are stored. This feature is off by default. This option can be used to map inodes to paths without requiring the search of directories to find the inode.
- xfs_io command
In IRIX 6.5.29, the xfs_io command includes the parent option that prints out the parent inode numbers, inode generation numbers and basenames of all the hardlinks which point to the inode of the current file.
- New extended inline allocation policy version on XFS filesystems
A new version of extended attribute inline allocation policy uses a more efficient algorithm for managing the available inline inode space.
- filestreams mount option
IRIX 6.5.29 includes the new 'filestreams' mount option, which changes the behavior of the XFS allocator in order to optimize disk layout for workloads that issue a stream of file creations into a directory.

Important note if you do live installs of the IRIX 6.5.xx releases
IRIX 6.5.xx Lookahead
- Updated Inst program
New installation features were used starting with IRIX 6.5.21 that necessitate an updated version of the Inst program. If you plan to install using the miniroot, then you may do so by the usual method. However, if you plan to upgrade by 'live' install and are running IRIX 6.5.19 or earlier, you must first install patch 5086.
IRIX 6.5.30 is in development and is planned to release mid-August, 2006.
