Strange NFS client behavior

Hello,

Since a few days, I’ve noticed a strange and abnormal behavior on my machine with Leap 15.4 as a NFS client. This behavior is new, although I did not change my configuration. Furthermore, I do not see this behavior on another Leap 15.4 machine, also acting as NFS client, and a priori configured the same way.

In an NFS share, if I create a file or a directory, it is not listed in the subsequent ls, but it seems nevertheless to be created (also checked to be present on the NFS server’s physical media).

> mkdir test
> echo "Test" > test.txt
> ls
(no mention of test or test.txt)
> mkdir test
mkdir: cannot create directory ‘test’: File exists

Also, if I move an existing file to a directory, the NFS client does not seem to track this move correctly (although it is correctly moved on the NFS server’s physical media).

> mv myfile.jpg directory/
> ls -l
-????????? ? ?      ?           ?            ? myfile.jpg
> mv directory/myfile.jpg .
(the file is correctly back)

Any idea what could be causing this?

Thanks & kind regards,
Gilles

PS: If it helps, here is how the NFS share is mounted:

192.168.1.48:/media/RG on /media/RG type nfs4 (rw,relatime,vers=4.2,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.46,local_lock=none,addr=192.168.1.48,_netdev)

Are both systems using the same exported resources from the same NFS server?

Yes, and using the same options.

The only difference is that this other system is a bit behind in terms of updates. I’ll do the update to see if it is significant.

I let the updates install, unchanged situation: strange behavior on my main system, fine behavior on the other system.

Worst case, I’ll redo a fresh installation… :grinning:
