(am-utils.info)opts Option
opts Option
...........
The options to pass to the mount system call. A leading `-' is
silently ignored. The mount options supported generally correspond to
those used by mount(8) and are listed below. Some additional
pseudo-options are interpreted by Amd and are also listed.
Unless specifically overridden, each of the system default mount
options applies. Any options not recognized are ignored. If no
options list is supplied the string `rw,defaults' is used and all the
system default mount options apply. Options which are not applicable
for a particular operating system are silently ignored. For example,
only 4.4BSD is known to implement the `compress' and `spongy' options.
`acdirmax=N'
Set the maximum directory attribute cache timeout to N.
`acdirmin=N'
Set the minimum directory attribute cache timeout to N.
`acregmax=N'
Set the maximum file attribute cache timeout to N.
`acregmin=N'
Set the minimum file attribute cache timeout to N.
`actimeo=N'
Set the overall attribute cache timeout to N.
`auto'
`ignore'
Ignore this mount by df(1).
`cache'
Allow data to be cached from a remote server for this mount.
`compress'
Use NFS compression protocol.
`defperm'
Ignore the permission mode bits, and default file permissions to
0555, UID 0, and GID 0. Useful for CD-ROMs formatted as ISO-9660.
`dev'
Allow local special devices on this filesystem.
`dumbtimr'
Turn off the dynamic retransmit timeout estimator. This may be
useful for UDP mounts that exhibit high retry rates, since it is
possible that the dynamically estimated timeout interval is too
short.
`extatt'
Enable extended attributes in ISO-9660 file systems.
`fsid'
Set ID of filesystem.
`gens'
Enable generations in ISO-9660 file systems. Generations allow
you to see all versions of a given file.
`grpid'
Use BSD directory group-id semantics.
`int'
`intr'
Allow keyboard interrupts on hard mounts.
`lock'
Use the NFS locking protocol (default)
`multi'
Perform multi-component lookup on files.
`maxgroups'
Set the maximum number of groups to allow for this mount.
`nfsv3'
Use NFS Version 3 for this mount.
`noac'
Turn off the attribute cache.
`noauto'
This option is used by the mount command in `/etc/fstab' or
`/etc/vfstab' and means not to mount this file system when mount -a
is used.
`nocache'
Do not allow data to be cached from a remote server for this mount.
`noconn'
Don't make a connection on datagram transports.
`nocto'
No close-to-open consistency.
`nodefperm'
Do not ignore the permission mode bits. Useful for CD-ROMS
formatted as ISO-9660.
`nodev'
`nodevs'
Don't allow local special devices on this filesystem.
`noexec'
Don't allow program execution.
`noint'
Do not allow keyboard interrupts for this mount
`nolock'
Do not use the NFS locking protocol
`nomnttab'
This option is used internally to tell Amd that a Solaris 8 system
using mntfs is in use.
`norrip'
Turn off using of the Rock Ridge Interchange Protocol (RRIP)
extensions to ISO-9660.
`nosub'
Disallow mounts beneath this mount.
`nosuid'
Don't allow set-uid or set-gid executables on this filesystem.
`noversion'
Strip the extension `;#' from the version string of files recorded
on an ISO-9660 CD-ROM.
`optionstr'
Under Solaris 8, provide the kernel a string of options to parse
and show as part of the special in-kernel mount file system.
`overlay'
Overlay this mount on top of an existing mount, if any.
`pgthresh=N'
Set the paging threshold to N kilobytes.
`port=N'
Set the NFS port to N.
`posix'
Turn on POSIX static pathconf for mounts.
`proplist'
Support property lists (ACLs) for this mount, useful primarily for
DU-4.0.
`proto=S'
Use transport protocol S for NFS (can be `"tcp"' or `"udp"').
`quota'
Enable quota checking on this mount.
`rdonly'
`ro'
Mount this filesystem readonly.
`resvport'
Use a reserved port (smaller than 1024) for remote NFS mounts.
Most systems assume that, but some allow for mounts to occur on
non-reserved ports. This causes problems when such a system
tries to NFS mount one that requires reserved ports. It is
recommended that this option always be on.
`retrans=n'
The number of NFS retransmits made before a user error is
generated by a `soft' mounted filesystem, and before a `hard'
mounted filesystem reports `NFS server "yoyo" not responding still
trying'.
`retry'
Set the NFS retry counter.
`rrip'
Uses the Rock Ridge Interchange Protocol (RRIP) extensions to
ISO-9660.
`rsize=N'
The NFS read packet size. You may need to set this if you are
using NFS/UDP through a gateway or a slow link.
`rw'
Allow reads and writes on this filesystem.
`soft'
Give up after "retrans" retransmissions.
`spongy'
Like `soft' for status requests, and `hard' for data transfers.
`suid'
Allow set-uid programs on this mount.
`symttl'
Turn off the symbolic link cache time-to-live.
`sync'
Perform synchronous filesystem operations on this mount.
`tcp'
Use TCP/IP instead of UDP/IP, ignored if the NFS implementation
does not support TCP/IP mounts.
`timeo=N'
The NFS timeout, in tenth-seconds, before a request is
retransmitted.
`vers=N'
Use NFS protocol version number N (can be 2 or 3).
`wsize=N'
The NFS write packet size. You may need to set this if you are
using NFS/UDP through a gateway or a slow link.
The following options are implemented by Amd, rather than being
passed to the kernel.
`nounmount'
Configures the mount so that its time-to-live will never expire.
This is also the default for some filesystem types.
`ping=N'
The interval, in seconds, between keep-alive pings. When four
consecutive pings have failed the mount point is marked as hung.
This interval defaults to 30 seconds. If the ping interval is
less than zero, no pings are sent and the host is assumed to be
always up. By default, pings are not sent for an NFS/TCP mount.
`retry=N'
The number of times to retry the mount system call.
`utimeout=N'
The interval, in seconds, by which the mount's time-to-live is
extended after an unmount attempt has failed. In fact the
interval is extended before the unmount is attempted to avoid
thrashing. The default value is 120 seconds (two minutes) or as
set by the `-w' command line option.
