Description Lukas Herbolt 2021-06-21 10:43:50 UTC

Description of problem: kernel 8.4 started printing out warning about deprecated mount option. This leads to warning message whenever nfs is mounted via -hosts and host.net as both of them are using intr by default. 


Version-Release number of selected component (if applicable):


How reproducible:
Everytime

Steps to Reproduce:
1. Mount nfs via automout using -host option or auto.net

Actual results:
Following warning is printed:
kernel: nfs: Deprecated parameter 'intr'


Expected results:
Deprecated option is not used and no warning is printed.

Additional info:
The intr mount option was deprecated since kernel-2.6.25. ;-) 
So it was ignored even in RHEL 6.

Comment 2 Ian Kent 2021-06-22 11:56:01 UTC

To test this:
1) Setup an NFS server with some exports.
2) Ensure "logging = debug" is set in the /etc/autofs.conf.
3) Start autofs.
4) Ensure the "/net -hosts" line in /etc/auto.master is not commented out.
5) Run ls /net/<server-name>.
6) Stop autofs.

In the log (or journalctl output) you will see lines (in my case server
is gandalf) like :
mount(nfs): calling mount -t nfs -s -o nosuid,nodev,intr gandalf:/work /net/gandalf/work
since the exports will be automounted because of the aliase "ls='ls --color=auto'".

If the alias is not present in the testing environment use ls --color=auto to trigger
the mounts.

After the change the intr option will no longer be present.

The intr option is also removed from /etc/auto.net by the above patch.
