mount error(5): Input/output error
by mfoley from LinuxQuestions.org on (#6D0EN)
I have a Slackware 14.2 system configured as a Windows Active Directory / Domain Controller. For many years I've had a script on this server that mounts the domain's various Windows 10 workstation's C: drives to scan for bogus downloads, etc. This script runs daily after business hours. The C: drives are marked as shared, accessible by the domain administrator.
Starting 4 days ago, this script started failing:
Code:> mount //dbserver/C /mnt/tmp -o vers=2.1,username=adminuser,rw,password=adminpw
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)I've rebooted the computer. I've tried several things I've found on the web including chaning vers to 2.0 and 3.0, adding sec=ntlm, verifying the admin account is not locked out. Nothing has helped.
Nothing has changed on the Linux server prior to this -- no upgrades, etc. I am suspecting something changed on the Windows workstations. Suspiciously, the very day this script stopped working (7/12/2023) there were two Windows updates, "2023-07 Cumulative Update for Windows 10 Version 22H2 for x64-bases Systems (KB5028166)" and "Cumulative Update for .NET Framework 3.4, 4.8 and 4.81 for Windows 10 Version 22H2 for x64 (KB5028937).
Any idea what could be causing the problem?
