Public bug reported: I have a Ubuntu Server (14.04.5 LTS (GNU/Linux 4.4.0-98-generic x86_64)) and a Windows Server 2012 R2 File Server with a File Share. I mounted a file share to my linux server with a cifs-utils. Everything worked fine until some kernel update installed on Ubuntu. SMB 3.0 stopped working and my share not mounted.
sudo mount -t cifs //myserver.xxx.net/WebBackup -o username=user,password=P@ssw0rd,domain=xxx.net,vers=3.0 /backupdrive - not working mount error(5): Input/output error Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) if i change to vers=2.1 - it it work ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730607 Title: mount cifs with SMB 3.0 stop working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1730607/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
