What's the best way to make autofs aware of any changes to its map files (e.g. changes in
auto.home
below) without the need to stop the service on RHEL 6.7?
According to autofs man page
> If a map is modified then the change will become effective immediately. If the auto.master map is modified then the autofs script must be rerun to activate the changes.
However, if I change my auto.home
the changes are not automatically seen by autofs. In addition, if I then run service autofs reload
the changes are still not seen. The changes become effective only after I run service autofs restart
. However, this would require all the users to stop working on any NFS-shared folders until the restart of the service completes.
Shouldn't the changes take effect automatically or at least after I run service autofs reload
? What am I doing wrong here?
See below for the configuration I use:
----------
I have the following simple configuration on two RedHat Linux 6.7 machines, one is acting as the NFS server and the second as the client.
NFS Server:
$ cat /etc/exports
/home/user1/NFS-test *(rw,sync)
/home/user2/NFS-test *(rw,sync)
NFS Client:
$ cat /etc/auto.master
/misc /etc/auto.misc
/net -hosts
/- /etc/auto.home --temeout=300
+auto.master
$ cat /etc/auto.home
/home/user1/NFS-test -ro,soft,intr server:/home/user1/NFS-test
/home/user2/NFS-test -ro,soft,intr server:/home/user2/NFS-test
This works fine and both users (user1
and user2
) are able to see their own NFS-test
directory under their home folder on the client machine.
Now the second line is removed from auto.home
such that
$ cat /etc/auto.home
/home/user1/NFS-test -ro,soft,intr server:/home/user1/NFS-test
Then I run service autofs reload
in order to update the shares. However, the change in auto.home
is not seen and /home/user2/NFS-test
continues to be accessible from the client machine.
If on the other hand I run service autofs restart
then the mapping is correctly updated /home/user2/NFS-test
is not visible on the client.
I would like to be able to refresh the NFS shares in response to changes in auto.home
without needing to stop autofs first in order to avoid asking all the users to logout first. Is this possible with reload
? Is there another way for doing this?
----------
**UPDATE**
Since my setup is relatively small (1 server and 3 clients) and with only two folders being exported (one read-only and one read-write), I decided to drop the use of autofs
and use directly NFS by editing /etc/fstab
on each client. For such a small setup I hope that there won't be any noticable difference in performance compared to autofs
. If someone thinks otherwise, please let me know.
In case someone is interested, here is the setup I went for:
The server exports the following folders:
- /export
: where all the software will be located (read-only)
- /home/shared_homes
: here each user has a folder which is exported to all clients and which is automatically linked in to its home directory. For example, the user bob101
will have a folder /home/shared_homes/bob101
which will be linked to /home/bob101/mySharedWorkspace
