We are using AMD version 5.1.1.6 (Rel5.1c) with map support for: root, yp,
file, error. We seem to have two problems with its usage, the first error
is most likely usage, as it is a problem on all our platforms (Sun3, Sun4
and Vax). (Since the problem is so easily descibed, only a brief explanation
is given below.) The second problem is only seen on the Vax, hence a problem
with this port. Sorry to be so verbose with the description of the problem,
but I assume the more data given the easier it will be to address it. All
comments are appreciated. I will attempt to summarize all errors below:
****************************************************************************
I. type:=ufs
This never works, on any architecture (Sun 3 - OS4.0.3, Sun 4 - OS
4.0.3c, Vax 11/780 - Ultrix 3.1 Rev 9) All report the same error:
"Mount device busy"
This is both with and without invoking amd with the "-r" option.
****************************************************************************
II. type:=link
This works wonderfully on the Suns, but gets extremely confused on the
Ultrix machine. Using the map file a_tron (shown below):
/defaults opts:=rw,intr,grpid,nosuid
#
# Partitions for machine tron - Vax 11/780 running Ultrix
tron type:=auto;fs:=${map};pref:=${key}/
tron/wusers host!=tron;type:=nfs;rhost:=tron;rfs:=/usr/users \
host==tron;type:=link;fs:=/usr/users
tron/var host!=tron;type:=nfs;rhost:=tron;rfs:=/var \
host==tron;type:=link;fs:=/var
tron/aux host!=tron;type:=nfs;rhost:=tron;rfs:=/aux \
host==tron;type:=link;fs:=/aux
tron/usr type:=auto;fs:=${map};pref:=${key}/
tron/usr/adm -sublink:=adm \
host!=tron;type:=nfs;rhost:=tron;rfs:=/var \
host==tron;type:=link;fs:=/var
tron/usr/local -sublink:=local \
host!=tron;type:=nfs;rhost:=tron;rfs:=/var \
host==tron;type:=link;fs:=/var
tron/usr/cad host!=tron;type:=nfs;rhost:=tron;rfs:=/usr/cad \
host==tron;type:=link;fs:=/usr/cad
tron/usr/dump host!=tron;type:=nfs;rhost:=tron;rfs:=/usr/dump \
host==tron;type:=link;fs:=/usr/dump
tron/usr/users host!=tron;type:=nfs;rhost:=tron;rfs:=/usr/users \
host==tron;type:=link;fs:=/usr/users
I invoke amd as follows: "amd -l log /rmt a_tron"
it works some of the time, but the times it does not I get errors such
as:

Enough of the examples. What I see happening, as I examine the symbolic
link, many it will appear to point in the right place, but the number of
characters the file actually contains indicate it must be pointing
somewhere else! This occurs much more prevelantly when I mount the /vol
map...
o If I attempt to change the a_tron map above to never perform a check
if localhost, then I again see problems, this time sublink is not being
examined. Assuming the file a_tron now contains:

Simply put, Ultrix has a difficult time finding any local partitions. I have
tried setting type:={ufs,link,nfs} and all seem to have problems. The
problems seen with link do not ocurr on the suns. (I never attempted to
access a local partition via nfs on the suns since link performs well.)
I also attempted to create the mount point directly on a local ufs partition,
as described in Section 6.2 of the TeX document, but was never successful in
getting it to mount an nfs directory when the ${key} was not local. This too
would be a satisfactory solution, if only we could get it to work.
Thanks again for all you time and effort. I have not posted this message to
the usenet as it is quite large and did not want to overwhelm the net with
such a huge message. I do appreciate your taking the time to look into this.
If you do not have a Vax running Ultrix, could you please let me know of
anyone who has had success. Thanks again for you response. Please forward
all responses to the address below.
