RedHat How to mount NFS using automounter(autofs)?
I have an nfs at 192.168.1.10:/home/vm1/Desktop/nfs and will like to mount locally to /home/vm1/Desktop/nfs-mount using automounter...need help doing do

What i did


$cat /etc/auto.master
Code:
/home/vm1/Desktop    /etc/auto.nfs

$cat /etc/auto.nfs
Code:
nfs-bind     -fstype=nfs    192.168.1.34:/home/vm1/Desktop/nfs

And yes autofs is running and is reloaded

Code:
[root@vm1 ~]# service autofs status
automount (pid  3534) is running...
[root@vm1 ~]# service autofs reload
Reloading maps

Is that the correct way to do that? If yes then why is it that its not working...nothing got mounted..nothing

You have specified an indirect map auto.nfs, mounted on /home/vm1/Desktop.
Code:
df /home/vm1/Desktop

will tell it's controlled by automount.
The key in auto.nfs is nfs-bind, so you will find the actual mount
Code:
cd /home/vm1/Desktop/nfs-bind
df .

If the NFS server denies the mount (no NFS share access) it should be syslogged to /var/log/messages.
But some autofs5 versions don't log it (but log other things that do not make sense at all). So, as root, test it with a manual mount:
Code:
mkdir -p /mnt
mount 192.168.1.34:/home/vm1/Desktop/nfs /mnt
umount /mnt

Just noticed something strange

Code:
[root@vm1 ~]# cd /home/vm1/Desktop/nfs-bind
-bash: cd: /home/vm1/Desktop/nfs-bind: No such file or directory
[root@vm1 ~]# ls -lh /home/vm1/Desktop
total 0

I cannot list the files and folders under /home/vm1/Desktop anymore..what is going on here? Something went wrong and can't figure it out...i think this is probably the same reason i was finding it hard to mount nfs and samba/cifs as well


Another strange thing...i restarted the system and i lost all folders and files created under /home/vm1/Desktop..Desktop is not back to default like fresh install...what is going on here? Before i restarted i could see the folders and files on the desktop even though i got the error that directory does not exist (from above) but now after restart...the desktop is back to default...all folders created before are gone/disappeared

I cannot mkdir as root
please see below

Code:
[root@vm1 ~]# mkdir /home/vm1/Desktop/nfs
mkdir: cannot create directory `/home/vm1/Desktop/nfs': Permission denied

so i checked the selinux context below and got

Code:
[root@vm1 ~]# ls -Z /home/vm1
drwxrwxrwx. root root system_u:object_r:autofs_t:s0    Desktop
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:user_home_t:s0 Documents
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:user_home_t:s0 Downloads
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:audio_home_t:s0 Music
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:user_home_t:s0 Pictures
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:user_home_t:s0 Public
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:user_home_t:s0 Templates
drwxr-xr-x. vm1  vm1  unconfined_u:object_r:user_home_t:s0 Videos


Can someone tell me what is wrong here?
And yes i was trying to mount nfs using autofs at some point and wasn't running so seeing autofs there is confusing me..maybe it caused a problem somewhere...


also after the autofs problem i noticed the whole folders and files in /home/vm1/Desktop are all gone.

Please what happened?

Thanks

mount.nfs: access denied by server while mounting 192.168.1.34:/home

Check on the NFS server 192.168.1.34 why it denies NFS client vm1 access to the NFS share.
I am a bit confused, because you seem to have two mounts:
Code:
/home/vm1/nfs-mount 192.168.1.10:/home/vm1/Desktop/nfs
/home/vm1/nfs-bind  192.168.1.34:/home/vm1/Desktop/nfs

Then, vm1 seems to be both NFS client and NFS server?
Maybe somebody else is less confused?
