Introduced in IRIX 6.5.14:
• In the IRIX 6.5.5 release, SGI introduced a new optional directory
format for XFS filesystems, referred to as the "version 2" directory
format in mkfs output.
Beginning with the IRIX 6.5.14 release, version 2 directories of XFS
will be the default for all new filesystems created with mkfs.
Version 1 directory filesystem creation will still be supported, but this
will require that you specify the -n version=1 parameter of the
mkfs command.
SGI recommends that all new XFS filesystems be created with version
2 directories. IRIX releases older than IRIX 6.5.5, however, will not be
able to mount a filesystem created with a version 2 directory and will
issue the following message when a mount is attempted:
Wrong filesystem type: xfs
There is no means for converting a filesystem, in place, between
version 1 and version 2 directories. A filesystem can be converted
between version 1 and version 2 directories by means of an
xfsdump/mkfs/xfsrestore sequence.
For more information, see IRIX Admin: Disks and Filesystems.
•A-q cpuset_name -p option was added to the cpuset command that
allows you to see the properties of particular cpuset, such as, the
number of processes and CPUs associated with the specified cpuset.
