  What is Samba To provide printer and file sharing, Microsoft Windows uses a facility known as  SMB (Server Message Block) . This same facility is sometimes known as  NetBIOS  or  LanManager . Thanks to Andrew Tridgell and others, Linux systems provide support for SMB via a package known as Samba. Like SMB, Samba lets you: Share printers and files among Microsoft Windows, OS/2, Netware, and Unix systems Establish a simple nameserver for identifying systems on your local area network Backup PC files to a Linux system and restore them Administer users and passwords Samba has proven its reliability and high performance in many organizations.Samba software suite on Enterprise Linux is a collection of programs that implements the Server Message Block (commonly abbreviated as SMB) protocol for UNIX systems.

  /dev/sda3 - root partition 100% full due to Audit.log files not being rotated in vCenter Server Appliance (2149278) Last Updated:  22/4/2020 Categories:  Troubleshooting   38 Language:                   Chinese (Simplified) English                             subscribe   Symptoms 100% capacity used for  /dev/sda3 . Size of  audit.log  file is very large and  /var/log/audit  folder consumes majority of the space. Saved logs from log rotate policy reference a date that is not in line with the policy. Unable to connect to the vCenter Server as services are not started. Running  /etc/cron.daily/logrotate  manually rotates logs as expected. Accessing vSphere Web Client might fail with error:  503 service unavailable   Purpose This article provides steps to reduce the  audit.log  size.   Resolution To resolve this issue, truncate the  audit.log  file and verify the cron job is working correctly.   Truncate audit.log Log in to the vCenter Server Appliance through SSH. Run this command to en
