My Ubuntu Server has been connecting to my Server 2012 R2 DFS namespace for about 2 years now with no issues. After the last couple of rounds of updates (Ubuntu and Windows) I noticed that every couple of hours the mount would drop and not come back. Accessing the mount point /mnt/media would just completely freeze the session.
/var/samba/log is empty and there is nothing in the Windows logs of note.
CIFS VFS: Error -104 sending data on socket to server
Is the only error I can find!
The mount is from FSTAB:
//dfsnamespace/media /mnt/media/ cifs credentials=/etc/samba/user,noserverino 0 0
I'll notice that none of my media will play, I'll come and log into the server and do a 'sudo mount -a' and about 50% of the time it will come back. The other 50% nothing happens and I end up rebooting the server.
If I manually mount with smbclient, no problems!
Anyone have any ideas why:
- What's causing this issue in the first place
- Why the /var/logs/samba has no logs?
Any help is greatly appreciated!
