[SOLVED] Can't get autofs to work with NFS4

NFS share mounts successfully either from fstab or manual mount, but autofs doesn't seem to be able to handle it.
My /etc/autofs/auto.master:

/nfs	/etc/autofs/auto.nfs

/etc/autofs/auto.nfs:

mountpoint -fstype=nfs4 serv1:/mnt/stor

And then:

# systemctl reload autofs
$ cd /nfs/mountpoint/
bash: cd: /nfs/mountpoint/: No such file or directory

Am I doing something wrong with autofs?

Re: [SOLVED] Can't get autofs to work with NFS4

I remember my struggles with automounter being quickly resolved by doing:

automount -d -f

after shutting it down through systemd. This way, you can see how it moves.

Do post the logs if this does not work for you.

Here they are:

Those last 3 lines appear every time I try to cd into /nfs/mountpoint/

Re: [SOLVED] Can't get autofs to work with NFS4

Turned out my auto.nfs had executable bit and autofs is finicky about it: http://serverfault.com/questions/265744 … nfs-issues
After removing executable bit it works.

Re: [SOLVED] Can't get autofs to work with NFS4

The same problem, with exactly the same symptoms, can be caused by a failure to connect to rpcbind.  This is a server side issue since rpcbind is built against libwrap.so, so /etc/hosts.allow must permit a connection from the remote client, assuming you have a suitably restrictive /etc/hosts.deny policy in place.  Add

rpcbind : <address spec> : allow

to your /etc/hosts.allow file.
