Public bug reported: I run a samba server on an Ubuntu 14.10 host and have several ubuntu clients as VM as well as separate device for media streaming. On reboot for the VM's and media streamer sometimes the samba share connects without issue, sometimes it errors. In all cases I can reconnect the share with a manual mount command or a 'mount -a'.
Server process log never shows any errors, server client process logs never show error, only errors through are on the client which are either in dmesg output... Status code returned 0xc0000001 NT_STATUS_UNSUCCESSFUL CIFS VFS: Send error in SessSetup = -5 CIFS VFS: cifs_mount failed w/return code = -5 or on the cli directly after the mount command... mount error(5): Input/output error Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I've had this issue for many months and believed it to be a bad config somewhere as I could never find many other people with the similar symptoms (google). Today I've found a bug report on debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746229) with the same problems. I've tried lots of different parameters for the mount command to see if any generate a different error or less frequent error but cannot see any differents. My current mount command for a VM which demonstrates persistent issues is... //blackserver.273below.co.uk/share /mnt/share cifs username=XXXXX,password=XXXXX,sec=ntlm,hard 0 0 I've tried appending workgroup parameters into the mount etc and nothing seems to resolve.
