I'm accessing a samba share on a Windows Server 2019 from a PC with an updated Debian 10 buster OS with the command:

sudo mount -t cifs -o vers=3.11,username=myname,uid=1000,gid=1000 //the.server/some/share/ /home/myname/some/dir

On the top level I'm able to create and rename files without problems:

>> cd ~/some/dir
>> touch del.me
>> mv del.me del1.me

However, if I try to rename a file in a subdirectory, it doesn't work anymore:

>> cd ~/some/dir
>> mkdir subdir
>> cd subdir
>> touch del.me
>> ls -la
total 8
drwxr-xr-x 2 myname myname    0 Apr 27 11:56 .
drwxr-xr-x 2 myname myname 8192 Apr 27 11:56 ..
-rwxr-xr-x 1 myname myname    0 Apr 27 11:56 del.me
>> mv del.me del1.me    
mv: cannot move 'del.me' to 'del1.me': No such file or directory

Deleting the file created in the subdirectory with rm del.me works without problems.

What could be the reason? I've tried looking online for the problem but cannot find a solution. In other shares on the same server (//the.server/another/share/) mounted in the same way and with the same permissions, moving files works without problems. I've also tried accessing the share from a different PC (running a Debian testing OS), and the problem persists. My samba version is 4.9.5-Debian.

  • Can you cat del.me or ls -l del.me?

  • @roaima The ls -l is shown above. For the example shown, since I just "touched" it, del.me is empty, but I have the problem with files with content too. Running cat doesn't give any errors

  • I saw your ls -l, I'm curious to know about the ls -l del.me with an explicitly referenced file name

    @roaima noperm doesn't work either. The login name is the same...

    @roaima I fixed the problem specifying vers=1.0. I had already tried 3.11, 3.0 and 2.0 but had to go back even further. Thanks for the support!

The problem was fixed specifying version 1.0:

sudo mount -t cifs -o vers=1.0,username=myname,uid=1000,gid=1000 //the.server/some/share/ /home/myname/some/dir

The bug affects debian systems and is known since January 2021: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949394


When I've seen this error even sudo rm del.me didn't work for me. Touching the "nonexistent" file and then rm-ing did.
