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.
