|
||||
Bug Reports
|
||||
===========
|
||||
|
||||
Send all bug reports to `amd-dev@majordomo.cs.columbia.edu' quoting
|
||||
the details of the release and your configuration. These can be
|
||||
obtained by running the command `amd -v'. It would greatly help if you
|
||||
could provide a reproducible procedure for detecting the bug you are
|
||||
reporting.
|
||||
|
||||
Mailing List
|
||||
============
|
||||
|
||||
There are two mailing lists for people interested in keeping
|
||||
up-to-date with developments.
|
||||
|
||||
1. The older list, `amd-workers' is for general "how to" questions and
|
||||
announcements. To subscribe, send a note to
|
||||
`amd-workers-request@majordomo.glue.umd.edu'.(1) To post a
|
||||
message to this list, send mail to
|
||||
`amd-workers@majordomo.glue.umd.edu'.
|
||||
|
||||
2. The developers only list, `amd-dev' is for
|
||||
|
||||
- announcements of alpha and beta releases of am-utils
|
||||
|
||||
- reporting of bugs and patches
|
||||
|
||||
- discussions of new features for am-utils
|
||||
|
||||
- implementation and porting issues
|
||||
|
||||
To subscribe, send a note to `amd-dev@majordomo.cs.columbia.edu'.
|
||||
To post a message to this list, send mail to
|
||||
`amd-dev@majordomo.cs.columbia.edu'. To avoid as much spam as
|
||||
possible, only subscribers to this list may post to it.
|
||||
|
||||
Subscribers of `amd-dev' are most suitable if they have the time
|
||||
and resources to test new and buggy versions of amd, on as many
|
||||
different platforms as possible. They should also be prepared to
|
||||
learn and use the GNU Autoconf, Automake, and Libtool packages,
|
||||
and of course, be very familiar with the complex code in the
|
||||
am-utils package. In other words, subscribers on this list should
|
||||
be able to contribute meaningfully to the development of amd.

Introduction
|
||||
************
|
||||
|
||||
An "automounter" maintains a cache of mounted filesystems.
|
||||
Filesystems are mounted on demand when they are first referenced, and
|
||||
unmounted after a period of inactivity.
|
||||
|
||||
Amd may be used as a replacement for Sun's automounter. The choice
|
||||
of which filesystem to mount can be controlled dynamically with
|
||||
"selectors". Selectors allow decisions of the form "hostname is THIS,"
|
||||
or "architecture is not THAT." Selectors may be combined arbitrarily.
|
||||
Amd also supports a variety of filesystem types, including NFS, UFS and
|
||||
the novel "program" filesystem. The combination of selectors and
|
||||
multiple filesystem types allows identical configuration files to be
|
||||
used on all machines thus reducing the administrative overhead.
|
||||
|
||||
Amd ensures that it will not hang if a remote server goes down.
|
||||
Moreover, Amd can determine when a remote server has become
|
||||
inaccessible and then mount replacement filesystems as and when they
|
||||
become available.
|
||||
|
||||
Amd contains no proprietary source code and has been ported to
|
||||
numerous flavors of Unix.

History
|
||||
*******
|
||||
|
||||
The Amd package has been without an official maintainer since 1992.
|
||||
Several people have stepped in to maintain it unofficially. Most
|
||||
notable were the `upl' (Unofficial Patch Level) releases of Amd,
|
||||
created by me (Erez Zadok), and available from
|
||||
ftp://ftp.cs.columbia.edu/pub/amd/. The last such unofficial release
|
||||
was `upl102'.
|
||||
|
||||
Through the process of patching and aging, it was becoming more and
|
||||
more apparent that Amd was in much need of revitalizing. Maintaining
|
||||
Amd had become a difficult task. I took it upon myself to cleanup the
|
||||
code, so that it would be easier to port to new platforms, add new
|
||||
features, keep up with the many new feature requests, and deal with the
|
||||
never ending stream of bug reports.
|
||||
|
||||
I have been working on such a release of Amd on and off since
|
||||
January of 1996. The new suite of tools is currently named "am-utils"
|
||||
(AutoMounter Utilities), in line with GNU naming conventions, befitting
|
||||
the contents of the package. In October of 1996 I had received enough
|
||||
offers to help me with this task that I decided to make a mailing list
|
||||
for these group of people. Around the same time, Amd had become a
|
||||
necessary part of my PhD thesis work, resulting in more work performed
|
||||
on am-utils.
|
||||
|
||||
Am-utils version 6.0 was numbered with a major new release number to
|
||||
distinguish it from the last official release of Amd (5.x). Many new
|
||||
features have been added such as a GNU `configure' system, NFS Version
|
||||
3, Autofs support, a run-time configuration file (`amd.conf'), many new
|
||||
ports, more scripts and programs, as well as numerous bug fixes.
|
||||
Another reason for the new major release number was to alert users of
|
||||
am-utils that user-visible interfaces may have changed. In order to
|
||||
make Amd work well for the next 10 years, and be easier to maintain, it
|
||||
was necessary to remove old or unused features, change various syntax
|
||||
files, etc. However, great care was taken to ensure the maximum
|
||||
possible backwards compatibility.

********
|
||||
|
||||
Amd maintains a cache of mounted filesystems. Filesystems are
|
||||
"demand-mounted" when they are first referenced, and unmounted after a
|
||||
period of inactivity. Amd may be used as a replacement for Sun's
|
||||
automount(8) program. It contains no proprietary source code and has
|
||||
been ported to numerous flavors of Unix. *Note Supported Platforms::.
|
||||
|
||||
Amd was designed as the basis for experimenting with filesystem
|
||||
layout and management. Although Amd has many direct applications it is
|
||||
loaded with additional features which have little practical use. At
|
||||
some point the infrequently used components may be removed to streamline
|
||||
the production system.

|
||||
Fundamentals
|
||||
============
|
||||
|
||||
The fundamental concept behind Amd is the ability to separate the
|
||||
name used to refer to a file from the name used to refer to its physical
|
||||
storage location. This allows the same files to be accessed with the
|
||||
same name regardless of where in the network the name is used. This is
|
||||
very different from placing `/n/hostname' in front of the pathname
|
||||
since that includes location dependent information which may change if
|
||||
files are moved to another machine.
|
||||
|
||||
By placing the required mappings in a centrally administered
|
||||
database, filesystems can be re-organized without requiring changes to
|
||||
configuration files, shell scripts and so on.
|
||||
|
||||
|
||||

|
||||
|
||||
Filesystems and Volumes
|
||||
=======================
|
||||
|
||||
Amd views the world as a set of fileservers, each containing one or
|
||||
more filesystems where each filesystem contains one or more "volumes".
|
||||
Here the term "volume" is used to refer to a coherent set of files such
|
||||
as a user's home directory or a TeX distribution.
|
||||
|
||||
In order to access the contents of a volume, Amd must be told in
|
||||
which filesystem the volume resides and which host owns the filesystem.
|
||||
By default the host is assumed to be local and the volume is assumed to
|
||||
be the entire filesystem. If a filesystem contains more than one
|
||||
volume, then a "sublink" is used to refer to the sub-directory within
|
||||
the filesystem where the volume can be found.
|
||||
|
||||
|
||||
File: am-utils.info, Node: Volume Naming, Next: Volume Binding, Prev: Filesystems and Volumes, Up: Overview
|
||||
|
||||
Volume Naming
|
||||
=============
|
||||
|
||||
Volume names are defined to be unique across the entire network. A
|
||||
volume name is the pathname to the volume's root as known by the users
|
||||
of that volume. Since this name uniquely identifies the volume
|
||||
contents, all volumes can be named and accessed from each host, subject
|
||||
to administrative controls.
|
||||
|
||||
Volumes may be replicated or duplicated. Replicated volumes contain
|
||||
identical copies of the same data and reside at two or more locations in
|
||||
the network. Each of the replicated volumes can be used
|
||||
interchangeably. Duplicated volumes each have the same name but contain
|
||||
different, though functionally identical, data. For example,
|
||||
`/vol/tex' might be the name of a TeX distribution which varied for
|
||||
each machine architecture.
|
||||
|
||||
Amd provides facilities to take advantage of both replicated and
|
||||
duplicated volumes. Configuration options allow a single set of
|
||||
configuration data to be shared across an entire network by taking
|
||||
advantage of replicated and duplicated volumes.
|
||||
|
||||
Amd can take advantage of replacement volumes by mounting them as
|
||||
required should an active fileserver become unavailable.
|
||||
|
||||
|
||||
File: am-utils.info, Node: Volume Binding, Next: Operational Principles, Prev: Volume Naming, Up: Overview
|
||||
|
||||
Volume Binding
|
||||
==============
|
||||
|
||||
Unix implements a namespace of hierarchically mounted filesystems.
|
||||
Two forms of binding between names and files are provided. A "hard
|
||||
link" completes the binding when the name is added to the filesystem. A
|
||||
"soft link" delays the binding until the name is accessed. An
|
||||
"automounter" adds a further form in which the binding of name to
|
||||
filesystem is delayed until the name is accessed.
|
||||
|
||||
The target volume, in its general form, is a tuple (host, filesystem,
|
||||
sublink) which can be used to name the physical location of any volume
|
||||
in the network.
|
||||
|
||||
When a target is referenced, Amd ignores the sublink element and
|
||||
determines whether the required filesystem is already mounted. This is
|
||||
done by computing the local mount point for the filesystem and checking
|
||||
for an existing filesystem mounted at the same place. If such a
|
||||
filesystem already exists then it is assumed to be functionally
|
||||
identical to the target filesystem. By default there is a one-to-one
|
||||
mapping between the pair (host, filesystem) and the local mount point so
|
||||
this assumption is valid.
|
||||
|
||||
|
||||
File: am-utils.info, Node: Operational Principles, Next: Mounting a Volume, Prev: Volume Binding, Up: Overview
|
||||
|
||||
Operational Principles
|
||||
======================
|
||||
|
||||
Amd operates by introducing new mount points into the namespace.
|
||||
These are called "automount" points. The kernel sees these automount
|
||||
points as NFS filesystems being served by Amd. Having attached itself
|
||||
to the namespace, Amd is now able to control the view the rest of the
|
||||
system has of those mount points. RPC calls are received from the
|
||||
kernel one at a time.
|
||||
|
||||
When a "lookup" call is received Amd checks whether the name is
|
||||
already known. If it is not, the required volume is mounted. A
|
||||
symbolic link pointing to the volume root is then returned. Once the
|
||||
symbolic link is returned, the kernel will send all other requests
|
||||
direct to the mounted filesystem.
|
||||
|
||||
If a volume is not yet mounted, Amd consults a configuration
|
||||
"mount-map" corresponding to the automount point. Amd then makes a
|
||||
runtime decision on what and where to mount a filesystem based on the
|
||||
information obtained from the map.
|
||||
|
||||
Amd does not implement all the NFS requests; only those relevant to
|
||||
name binding such as "lookup", "readlink" and "readdir". Some other
|
||||
calls are also implemented but most simply return an error code; for
|
||||
example "mkdir" always returns "read-only filesystem".
|
||||
|
||||
|
||||
File: am-utils.info, Node: Mounting a Volume, Next: Automatic Unmounting, Prev: Operational Principles, Up: Overview
|
||||
|
||||
Mounting a Volume
|
||||
=================
|
||||
|
||||
Each automount point has a corresponding mount map. The mount map
|
||||
contains a list of key-value pairs. The key is the name of the volume
|
||||
to be mounted. The value is a list of locations describing where the
|
||||
filesystem is stored in the network. In the source for the map the
|
||||
value would look like
|
||||
|
||||
location1 location2 ... locationN
|
||||
|
||||
Amd examines each location in turn. Each location may contain
|
||||
"selectors" which control whether Amd can use that location. For
|
||||
example, the location may be restricted to use by certain hosts. Those
|
||||
locations which cannot be used are ignored.
|
||||
|
||||
Amd attempts to mount the filesystem described by each remaining
|
||||
location until a mount succeeds or Amd can no longer proceed. The
|
||||
latter can occur in three ways:
|
||||
|
||||
* If none of the locations could be used, or if all of the locations
|
||||
caused an error, then the last error is returned.
|
||||
|
||||
* If a location could be used but was being mounted in the
|
||||
background then Amd marks that mount as being "in progress" and
|
||||
continues with the next request; no reply is sent to the kernel.
|
||||
|
||||
* Lastly, one or more of the mounts may have been "deferred". A
|
||||
mount is deferred if extra information is required before the
|
||||
mount can proceed. When the information becomes available the
|
||||
mount will take place, but in the mean time no reply is sent to
|
||||
the kernel. If the mount is deferred, Amd continues to try any
|
||||
remaining locations.
|
||||
|
||||
Once a volume has been mounted, Amd establishes a "volume mapping"
|
||||
which is used to satisfy subsequent requests.
|
||||
|
||||
|
||||
File: am-utils.info, Node: Automatic Unmounting, Next: Keep-alives, Prev: Mounting a Volume, Up: Overview
|
||||
|
||||
Automatic Unmounting
|
||||
====================
|
||||
|
||||
To avoid an ever increasing number of filesystem mounts, Amd removes
|
||||
volume mappings which have not been used recently. A time-to-live
|
||||
interval is associated with each mapping and when that expires the
|
||||
mapping is removed. When the last reference to a filesystem is removed,
|
||||
that filesystem is unmounted. If the unmount fails, for example the
|
||||
filesystem is still busy, the mapping is re-instated and its
|
||||
time-to-live interval is extended. The global default for this grace
|
||||
period is controlled by the "-w" command-line option (*note -w: -w
|
||||
Option.) or the amd.conf parameter `dismount_interval' (*note
|
||||
dismount_interval Parameter::.). It is also possible to set this value
|
||||
on a per-mount basis (*note opts: opts Option.).
|
||||
|
||||
Filesystems can be forcefully timed out using the Amq command.
|
||||
*Note Run-time Administration::.

||||

|
||||
|
||||
Keep-alives
|
||||
===========
|
||||
|
||||
Use of some filesystem types requires the presence of a server on
|
||||
another machine. If a machine crashes then it is of no concern to
|
||||
processes on that machine that the filesystem is unavailable. However,
|
||||
to processes on a remote host using that machine as a fileserver this
|
||||
event is important. This situation is most widely recognized when an
|
||||
NFS server crashes and the behavior observed on client machines is that
|
||||
more and more processes hang. In order to provide the possibility of
|
||||
recovery, Amd implements a "keep-alive" interval timer for some
|
||||
filesystem types. Currently only NFS makes use of this service.
|
||||
|
||||
The basis of the NFS keep-alive implementation is the observation
|
||||
that most sites maintain replicated copies of common system data such as
|
||||
manual pages, most or all programs, system source code and so on. If
|
||||
one of those servers goes down it would be reasonable to mount one of
|
||||
the others as a replacement.
|
||||
|
||||
The first part of the process is to keep track of which fileservers
|
||||
are up and which are down. Amd does this by sending RPC requests to the
|
||||
servers' NFS `NullProc' and checking whether a reply is returned.
|
||||
While the server state is uncertain the requests are re-transmitted at
|
||||
three second intervals and if no reply is received after four attempts
|
||||
the server is marked down. If a reply is received the fileserver is
|
||||
marked up and stays in that state for 30 seconds at which time another
|
||||
NFS ping is sent.
|
||||
|
||||
Once a fileserver is marked down, requests continue to be sent every
|
||||
30 seconds in order to determine when the fileserver comes back up.
|
||||
During this time any reference through Amd to the filesystems on that
|
||||
server fail with the error "Operation would block". If a replacement
|
||||
volume is available then it will be mounted, otherwise the error is
|
||||
returned to the user.
|
||||
|
||||
Although this action does not protect user files, which are unique on
|
||||
the network, or processes which do not access files via Amd or already
|
||||
have open files on the hung filesystem, it can prevent most new
|
||||
processes from hanging.
|
||||
|
||||
By default, fileserver state is not maintained for NFS/TCP mounts.
|
||||
The remote fileserver is always assumed to be up.
|
||||
|
||||
|
||||
File: am-utils.info, Node: Non-blocking Operation, Prev: Keep-alives, Up: Overview
|
||||
|
||||
Non-blocking Operation
|
||||
======================
|
||||
|
||||
Since there is only one instance of Amd for each automount point,
|
||||
and usually only one instance on each machine, it is important that it
|
||||
is always available to service kernel calls. Amd goes to great lengths
|
||||
to ensure that it does not block in a system call. As a last resort
|
||||
Amd will fork before it attempts a system call that may block
|
||||
indefinitely, such as mounting an NFS filesystem. Other tasks such as
|
||||
obtaining filehandle information for an NFS filesystem, are done using a
|
||||
purpose built non-blocking RPC library which is integrated with Amd's
|
||||
task scheduler. This library is also used to implement NFS keep-alives
|
||||
(*note Keep-alives::.).
|
||||
|
||||
Whenever a mount is deferred or backgrounded, Amd must wait for it
|
||||
to complete before replying to the kernel. However, this would cause
|
||||
Amd to block waiting for a reply to be constructed. Rather than do
|
||||
this, Amd simply "drops" the call under the assumption that the kernel
|
||||
RPC mechanism will automatically retry the request.
