On bionic, after firewalling off a cifs server, I just get a timeout after about 10s:
root@nsnx:~# mount //ds216.lowtech/downloads /ds216/downloads -t cifs -o username=andreas,uid=andreas Password for andreas@//ds216.lowtech/downloads: *** mount error(115): Operation now in progress Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) root@nsnx:~# If I try an IP that is not up, I get a different error after about 7s: root@nsnx:~# time mount //10.10.1.90/downloads /ds216/downloads -t cifs -o username=andreas,uid=andreas Password for andreas@//10.10.1.90/downloads: *** Unable to find suitable address. real 0m7.281s This is probably fixed then, but I'll mark this bug as incomplete pending new test cases showing that it hangs, and by hangs, I mean indefinitely. ** Changed in: cifs-utils (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/428129 Title: Mounting CIFS share hangs when server is offline To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/428129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
