Attributes Cache

The server’s attribute cache retains ﬁle attribute information on requests that have been made. This pro-

vides faster access to entries which have previously been decoded.

Lookup Cache

The Lookup Cache holds information about the sequential nature of the directory entries. This cache

stores the location of the next directory entry. When a request comes in for a directory entry, if the preced-

ing directory entry had been accessed earlier, this location is examined ﬁrst to see if the directory entry

being requested matches the directory entry at that location.

Block Cache

This cache holds raw 8k blocks of recently accessed data.

EXAMPLES

To mount a CD-ROM disk:

pfs_mount /dev/rdsk/c0t6d0 /cd-rom

To mount a remote ﬁle system:

pfs_mount serv:/cd-rom /cd-rom

To fake an entry for iso9660 on /cd-rom:

pfs_mount -f -t iso9660 /dev/rdsk/c0t6d0 /cd-rom

To hard mount a remote ﬁle system:

pfs_mount -o hard serv:/cd-rom /cd-rom

WARNINGS

PFS is obsolete and no longer supported on any HP-UX release. Delivery of PFS interfaces will be discon-

tinued in the next HP-UX release.

PFS, from Young Minds, Inc. (now defunct), was originally adopted by HP to provide accessibility to Rock

Ridge Interchange ﬁle system format on CD-ROM ﬁle systems. The equivalent functionality is now pro-

vided via the HP-UX CDFS ﬁle system type and HP-UX’s standard ﬁle systems commands.

PFS has known functionality and performance problems. HP customers are urged to stop using the PFS

interfaces, including these interfaces,

pfs_mount and pfs_umount . Customers should move to access-

ing all CD-ROM ﬁle system formats by using the standard HP-UX commands, specifying the ﬁle system

type as cdfs. For example, to mount a CD-ROM ﬁle system, use:

mount -F cdfs /dev/dsk/c0t0d4 /cdrom

There is no need to treat the cdfs ﬁle system type differently from any other ﬁle system type, therefore no

special daemons or commands are required to access the variety of CD-ROM ﬁle system formats.

See mount(1M) and mount_cdfs(1M).

Bugs

If the directory on which a ﬁle system is to be mounted is a symbolic link, the ﬁle system is mounted on the

directory to which the symbolic link refers, rather than being mounted on top of the symbolic link itself.

On Pioneer six disc changers (and perhaps other drives) if you mount the ﬁle system using the block device

driver, the Pioneer returns information to the driver indicating there is no data, causing the mount to fail.

Either mount the ﬁle system again (which will should succeed), or use the raw device driver.
