- filesystems: cdfs, dos, fat, EFS, hfs, mac, iso9660, cd-rom, kfs, nfs,
- XFS, rockridge - IRIX filesystem types
-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- IRIX supports a number of different filesystems. Some of these types are
- names that can be used with the _m_o_u_n_t(1) command's ----tttt option. Others are
- just common names and cannot be used with the _m_o_u_n_t command. An example
- of this is the RRRRoooocccckkkkRRRRiiiiddddggggeeee type, which is a superset of the iiiissssoooo9999666666660000
- filesystem type. Therefore RRRRoooocccckkkkRRRRiiiiddddggggeeee filesystems are mounted with a
- command similar to this:
-
- mount -t iso9660 -o ro /dev/rdsk/dks0d3vol /CDROM
-
- The following filesystem types are supported:
-
- bbbbddddssss Not a file system type, an extension to NFS for bulk data
- transfers. The BDSpro server is an optional product and must
- be purchased separately.
-
- ccccddddffffssss (CD-ROM)
- Same as type iso9660 (see below); this is the ABI compliant
- name.
-
- ddddoooossss (fat) The filesystem used by many personal computers. Types 1, 4,
- and 6 are supported, included long names where supported.
- Type 5 (extended partitions) are supported only if mounted
- with the ppppaaaarrrrttttiiiittttiiiioooonnnn #### options. IRIX support for ddddoooossss
- filesystems is restricted to removable disk devices such as
- floppy and floptical disks. Filenames on ddddoooossss filesystems are
- restricted to up to an eight character name followed by an
- optional period and three character filename extension, for
- most types. Longer names are supported to a limited degree,
- on the types where the native OS supports them.
-
- EEEEFFFFSSSS The older extent-based disk filesystem used by IRIX for disks
- and also for IRIX software distribution CD-ROMs. See _e_f_s(4)
- for more details.
-
- ffffdddd A filesystem used to access process file descriptors.
-
- hhhhffffssss (mac) The filesystem used by Macintosh computers. IRIX support for
- hhhhffffssss filesystems is restricted to removable disk devices such
- as floppy and floptical disks and to CD-ROMs. A hhhhffffssss file is
- composed of three portions: a data fork, a resource fork,
- and a desktop information entry. The data fork appears in a
- normal directory. The resource fork in a special directory
- (._H_S_R_e_s_o_u_r_c_e) in the file's directory. The desktop
- information for all files in a directory is contained in the
- special file ._H_S_a_n_c_i_l_l_a_r_y.

- iiiissssoooo9999666666660000 (CD-ROM)
- A CD-ROM filesystem type conforming to ISO standard 9660.
- iiiissssoooo9999666666660000 CD-ROMs are used when the contents of the CD-ROM is
- intended to be readable by a variety of operating systems.
- You must install the optional subsystem _e_o_e._s_w._c_d_r_o_m to be
- able to mount and read an iso9660 CD-ROM. Also see RRRRoooocccckkkkRRRRiiiiddddggggeeee
- below. Note that IRIX software distribution CD-ROMs are not
- iiiissssoooo9999666666660000 filesystems, they are eeeeffffssss filesystems. Music CDs are
- not file structured and are not used as filesystems. Music
- CDs can be played using the CD-ROM drive using _c_d_m_a_n(1) or
- _c_d_p_l_a_y_e_r(1).
-
- kkkkffffssss A network filesystem used to access disks on located on
- remote computers using AppleShare networking. Generally,
- AppleShare networking is used to access Macintosh computers.
- Except for the disk location, kkkkffffssss filesystems are identical
- to hhhhffffssss filesystems.
-
- nnnnffffssss A network filesystem used to access disks located on remote
- computers. Both NFS Version 2, and NFS Version 3 are
- supported. NFS is an optional product and must be purchased
- separately. The subsystem _n_f_s._s_w._n_f_s must be installed to
- use NFS.
-
- pppprrrroooocccc A filesystem that provides access to the image of each active
- process in the system.
-
- hhhhwwwwggggffffssss A filesystem that provides access to the system hardware
- configuration.
-
- RRRRoooocccckkkkRRRRiiiiddddggggeeee A filesystem layered on type of the iiiissssoooo9999666666660000 filesystem type
- (see above) that provides semantics closer to those of
- standard UNIX filesystems. In particular, it supplies file
- permissions and allows for directory hierarchies more than 8
- levels deep.
-
- XXXXFFFFSSSS The next-generation 64-bit high performance journaling
- filesystem used by IRIX for disks. See _x_f_s(4) for more
- details.
-
- ccccaaaacccchhhheeeeffffssss A caching filesystem for use with eeeeffffssss, xxxxffffssss, nnnnffffssss, nnnnffffssss3333,
- iiiissssoooo9999666666660000, hhhhffffssss, ddddoooossss, kkkkffffssss, and ccccddddffffssss. See _c_a_c_h_e_f_s(4) for
- details.
-
- NNNNOOOOTTTTEEEE
- The nnnnffffssss and kkkkffffssss filesystems are optional products. Support for iiiissssoooo9999666666660000
- filesystems is in the optional subsystem _e_o_e._s_w._c_d_r_o_m.
-
- IRIX implements ddddoooossss, hhhhffffssss, iiiissssoooo9999666666660000, and kkkkffffssss filesystems as user mode NFS
- daemons. In some cases errors detected by these daemons are reported as
- NFS errors. Although NFS is a product option, support for these
- filesystem types is not dependent on the installation of NFS.
