I just finished installing a copy of Windows 2012 and was testing version 3 when I came across this particular problem. To reproduce 1) First mount a share using vers=3.0 # mount -t cifs -o username=user1,password=pass1,vers=3.0 //vm140-54/exports /mnt This is successful. 2) Now unmount this share and attempt to mount with vers=2.0 to 2.1 # mount -t cifs -o username=user1,password=pass1,vers=2.1 //vm140-54/exports /mnt mount error(5): Input/output error Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) /var/log/messages shows kernel: [ 2730.843939] Status code returned 0xc0000203 STATUS_USER_SESSION_DELETED kernel: [ 2730.846883] CIFS VFS: Send error in SessSetup = -5 kernel: [ 2730.849247] CIFS VFS: cifs_mount failed w/return code = -5 I can then mount using vers=3.0 and vers=1.0 but not 2.0 or 2.1. I am attempting to debug this but was wondering if anyone had encountered this before.
