smb2-quota1

Userspace helper to display quota information for the linux smb client file system (cifs)

Overview

This tool is part of the cifs-utils suite.

smb2-quota is a userspace helper program for the Linux SMB client file system (CIFS).

This tool works by making an CIFS_QUERY_INFO IOCTL call to the Linux SMB client which in turn issues a SMB Query Info request and returns the result.

Options

--help/-h: Print help explaining the command line options.

--tabular/-t: Print quota information for the volume in tabular format. Amount Used | Quota Limit | Warning Level | Percent Used | Status | SID

--csv/-c: Print quota information for the volume in csv format. SID,Amount Used,Quota Limit,Warning Level

--list/-l: Print quota information for the volume in raw format. - SID - Quota Used - Quota Threshold - Quota Limit

--tabular/-t is the default action if none is given.

Notes

Kernel support for smb2-quota requires the CIFS_QUERY_INFO IOCTL which was initially introduced in the 4.20 kernel and is only implemented for mount points using SMB2 or above (see mount.cifs(8) vers option).
