Which command is useful for troubleshooting and obtaining information about CIFS mounts?

The command that is most useful for troubleshooting and obtaining information about CIFS mounts is indeed cifsstat. This command gathers statistics and information specifically related to CIFS (Common Internet File System) mounts, which are commonly used for accessing shared files over a network, particularly in environments that include Windows systems.

Using cifsstat provides insights into the performance and operational status of the CIFS connections, making it valuable for diagnosing issues or monitoring the behavior of CIFS shares. This can include details on the number of connections, file operations, and other metrics that can help identify problems with the mount or the network.

Individuals involved in maintaining mixed system environments—especially those that integrate Linux and Windows—often need to troubleshoot CIFS mounts for various reasons, including performance tuning or resolving connectivity issues. Being able to retrieve detailed information about these mounts with cifsstat is crucial for effective system administration.

The other choices either do not provide specific details about CIFS mounts or are more general commands that do not focus on CIFS. For example, mount.cifs is primarily used for mounting CIFS shares, not for obtaining diagnostic information. The df -h command offers disk space usage information but does not target CIFS specifically, and showmount pertains to NFS shares rather
