OK. I've been going at my desired implementation from several different
directions and not found anything that works satisfactorily.
I have a number of filesystems that I statically NFS mount from various
machines across the network here. I'd like to convert those all to
autofs mounted filesystems. Here's what I currently statically mount:
linux:/mnt/data /data nfs4
rw,vers=4,rsize=8192,wsize=8192,namlen=255,hard,nointr,proto=tcp,timeo=600,retrans=2,sec=krb5,clientaddr=10.75.22.1,addr=10.75.22.3
0 0
linux:/mnt/data/photos /data/photos nfs
rw,vers=4,rsize=32768,wsize=32768,namlen=255,hard,nointr,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5,clientaddr=10.75.22.1,addr=10.75.22.3
0 0
linux:/mnt/mp3 /mnt/mp3 nfs4
rw,vers=4,rsize=8192,wsize=8192,namlen=255,hard,nointr,proto=tcp,timeo=600,retrans=2,sec=krb5,clientaddr=10.75.22.1,addr=10.75.22.3
0 0
linux:/mnt/data/photos /data/photos nfs4
rw,vers=4,rsize=8192,wsize=8192,namlen=255,hard,nointr,proto=tcp,timeo=600,retrans=2,sec=krb5,clientaddr=10.75.22.1,addr=10.75.22.3
0 0
pvr:/video /video nfs
rw,relatime,vers=3,rsize=8192,wsize=8192,hard,nointr,proto=tcp,timeo=600,retrans=2,sec=sys,addr=10.75.22.2
0 0
jenny:/home/jennifer /autohome/jennifer nfs
rw,vers=3,rsize=8192,wsize=8192,namlen=255,soft,nointr,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.75.22.4,mountvers=3,mountproto=tcp,addr=10.75.22.4

Ideally, I'd like to just drop all of my mounts into aufofs, but as I
understand it mounting something like that /video or /data filesystems
requires direct maps and with the autofs 4.1.4 that I am using direct
mounts don't work? I could not get them to work in any case with such a
construct:
--- auto.master ---
/- /etc/auto.global
--- auto.global ---
/video pvr:/video
reloading autofs (/etc/init.d/autofs reload) seemed to completely ignore
the direct map.
So I decided that a /net map and a bunch of symlinks (even though having
to go to all of the machines and create symlinks will be a pain) might be
a better way to go.
On Ubuntu, they use a program map for /etc/auto.net which basically
mounts everything exported by the "key" given to the program. This is
pretty ugly... mounting every exported filesystem when access to only one
is needed.
So I then tried to use wildcards in an effort to just mount the single
filesystem needed under /net. That seemed to be a no go with the
following configuration:
--- auto.master ---
/net /etc/auto.net
--- auto.net ---
* -fstype=autofs,-Dhost=& file:/etc/auto.netsub
--- auto.netsub ---
* ${host}:/&
What seemed to have happened there was that when the key was being
truncated to the first / on any access. For example, when I tried to
access /net/linux/mnt/data, autofs tried to mount linux:/mnt.
So, what is the best (or any) way to get working what I want to do,
putting aside the ugly auto.net program map that mounts every exported
filesystem on every access to just any filesystem on the server?
Thanx in advance for any ideas you might have.
