qBittorrent & operating system versions

qBittorrent: 5.1.0-1 amd64
Operating system: Debian GNU/Linux 13 (trixie-testing)
Qt: --
libtorrent-rasterbar: 2.0.11-1 amd64

What is the problem?

Whenever I start qbittorrent-nox it disables server inode numbers on my cifs share mount.

I have the mount configured in fstab the same way on all my VMs. But on my qbittorrent-nox server, server inode numbers stop working. This prevents me form creating hardlinks from said server.

I have verified that starting qbittorrent-nox causes this issue. If I stop qbittorrent-nox, remount the cifs share, i can create hardlinks and all works well. But the moment I start qbittorrent-nox, the following error message is being displayed on the console of the VM qbittorrent is running on:

CIFS: VFS: Autodisabling the use of server inode numbers on \\192.168.1.1\share
CIFS: VFS: The server doesn't seem to support them properly or the files might be on different servers (DFS)
CIFS: VFS: Hardlinks will not be recognized on this mount. Consider mounting with the "noserverino" option to silence this message

I have some more Debian instances where I use the same fstab entry to mount my cifs share. The issue ins't happening on those instances and I can create hardlinks.

/etc/fstab:
//192.168.1.1/share /mnt/share cifs username=[REDACTED],password=[REDACTED],uid=qbittorrent,gid=smbshare,file_mode=0777,dir_mode=0777,cache=strict,serverino,mfsymlinks,nounix,x-system.automount 0 0

/proc/mounts before starting qbittorrent-nox:

qbittorrent@qBittorrent-Cross-Seed:~$ cat /proc/mounts | grep 192
//192.168.1.1/share /mnt/share cifs rw,relatime,vers=3.1.1,cache=strict,upcall_target=app,username=[REDACTED],uid=1004,forceuid,gid=1005,forcegid,addr=192.168.1.1,file_mode=0777,dir_mode=0777,soft,nounix,serverino,mapposix,mfsymlinks,reparse=nfs,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1 0 0

/proc/mounts after starting qbittorrent-nox (observe that the "serverino" option is gone):

qbittorrent@qBittorrent-Cross-Seed:~$ cat /proc/mounts | grep 192
//192.168.1.1/share /mnt/share cifs rw,relatime,vers=3.1.1,cache=strict,upcall_target=app,username=[REDACTED],uid=1004,forceuid,gid=1005,forcegid,addr=192.168.1.1,file_mode=0777,dir_mode=0777,soft,nounix,mapposix,mfsymlinks,reparse=nfs,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1 0 0

Steps to reproduce

  1. Edit /etc/fstab to mount a cifs share using the smb option "serverino"
  2. Verify the share is mounted
  3. Start the qbittorrent-nox service
  4. observe the syslog for CIFS error messages
