iso9660 will cause the mount program to attempt to mount the CD-ROM image using
the ISO 9660 specifications. If the CD image is not ISO 9660 compatible, the
mount fails. Note that if the CD image is also Rock Ridge compliant, and the
-t iso9660 option is not specified, the CD-ROM image will be mounted
with Rock Ridge extensions enabled.
hsfs will cause the mount program to attempt to mount the CD-ROM image using
the High Sierra specifications. If the CD image is not hsfs compatible, the
mount fails.
rrip will cause the mount program to attempt to mount the CD-ROM image using
the Rock Ridge Interchange specifications. If the CD image is not RRIP com-
patible, the mount fails. Note, that if the CD-ROM image supports the Rock
Ridge Interchange Protocol, and the CD-ROM image is mounted with rrip,
the translation options are suppressed.
Note that these get entered into the /etc/pfs_mtab and /etc/pfs_fstab with a
pfs- preceding the type.
-o options Specify file system options as a list of comma-separated words from the list below.
options valid on all file systems:
ro Even if not specified, the read-only option is implied.
suid |nosuid SetUID execution allowed or disallowed.
bg |fg If the first attempt fails, retry in the background, or, in the foreground.
retry=n The number of times to retry the mount operation.
rsize=n Set the read buffer size to n bytes.
timeo=n Set the PFS timeout to n tenths of a second.
retrans=n The number of PFS retransmissions.
soft |hard Return an error if the server does not respond, or continue the retry
request until the server responds.
intr Allow keyboard interrupts on hard mounts.
The defaults are:
suid,fg,retry=10000,timeo=7,rsize=2048,retrans=3,hard
options specific to iso9660 and hsfs file systems:
xlat=xlat_flags
xlat_flags is a colon (:) separated list of translation options. Currently
supported are no_version , dot_version, lower_case, and
unix. They allow you to perform the same translations options the -x
flag does. The -x flag remains for backward compatibility. It is sug-
gested that you use the xlat= option flag as they can be placed in the
/etc/pfs_fstab file.
pfs_umount Options
-v Verbose. Display a message indicating each file system as it is unmounted.
-a All. Unmount all PFS mounted file systems.
-c Close. Instruct the PFS daemons to close the given file system, but do not attempt to umount the file
system. This is useful when the file system has already been unmounted, but the PFS daemons still
have the source character device open.
pfs_mount CONFIGURATIONS
Background vs. Foreground
Filesystems mounted with the bg option indicate that pfs_mount is to retry in the background if the
server’s mount daemon (see pfs_mountd(1M)) does not respond. pfs_mount retries the request up to the
count specified in the retry=n option. Once the file system is mounted, each PFS request made in the
kernel waits timeo=n tenths of a second for a response. If no response arrives, the time-out is multiplied
by 2 and the request is retransmitted. When the number of retransmissions has reached the number
specified in the retrans=n option, a file system mounted with the soft option returns an error on the
request; one mounted with the hard option prints a warning message and continues to retry the request.
Interrupting Processes With Pending PFS Requests
The intr option allows keyboard interrupts to kill a process that is hung while waiting for a response on a
hard-mounted file system.
