autofs Troubles

[Ronald Wimmer]

Hi,

all over sudden automounting home shares has stopped working on one of 
our most important servers. The configuration has not changed at all. 
Automounting on servers with identical configuration works.

What i tried so far:

1) stopping rpcidmapd, rpcgssd, autofs, sssd and restarting the services

2) rebooting the system

3) doing ipa-client-automount --uninstall and reconfiguring it again

4) checking /etc/sysconfig/nfs and /etc/idmapd.conf as well as sssd.conf

5) automount -fv tells me that it attemts to mount /home but nothing happens

No matter what I tried I could not get homeshares mounted again.

I would highly appreciate any input that brings me one step further.

Cheers,
Ronald

Could you state the server's OS version, autofs version?
Can you restart autofs in debug mode?

Debug mode says:
mount(nfs): calling mount -t nfs4 -s -o rw,sec=krb5p 
ipanfs.linux.mydomain.at:/homeshare /home

spawn_mount: mtab link detected, passing -n to mount

Nothing happens...

The server is running CentOS Linux release 7.8.2003 (Core). Autofs is

automount -V

Linux automount version 5.0.7-109.el7

Directories:
     config dir:    /etc/sysconfig
     maps dir:    /etc
     modules dir:    /usr/lib64/autofs

Compile options:
   DISABLE_MOUNT_LOCKING ENABLE_IGNORE_BUSY_MOUNTS WITH_SYSTEMD
   WITH_HESIOD WITH_LDAP WITH_SASL LIBXML2_WORKAROUND WITH_LIBTIRPC
