vfs_extd_audit – record selected Samba VFS operations Synopsis vfs objects = extd_audit Description This VFS module is part of the samba(7) suite. The extd_audit VFS module records selected client operations to both the smbd(8) log and system log (using syslog(3)). Other than logging to the smbd(8) log, vfs_extd_audit is identical to vfs_audit(8). This module is…
vfs_dirsort – Sort directory contents Synopsis vfs objects = dirsort Description This VFS module is part of the samba(7) suite. The vfs_dirsort module sorts directory entries alphabetically before sending them to the client. Please be aware that adding this module might have negative performance implications for large directories. Examples Sort directories for all shares: [global]…
vfs_default_quota – store default quota records for Windows clients Synopsis vfs objects = default_quota Description This VFS module is part of the samba(7) suite. Many common quota implementations only store quotas for users and groups, but do not store a default quota. The vfs_default_quota module allows Samba to store default quota values which can be…
vfs_crossrename – server side rename files across filesystem boundaries Synopsis vfs objects = crossrename Description This VFS module is part of the samba(7) suite. The vfs_crossrename VFS module allows server side rename operations even if source and target are on different physical devices. A "move" in Explorer is usually a rename operation if it is…
vfs_commit – flush dirty data at specified intervals Synopsis vfs objects = commit Description This VFS module is part of the samba(7) suite. The vfs_commit VFS module keeps track of the amount of data written to a file and synchronizes it to disk when a specified amount accumulates. vfs_commit is useful in two circumstances. First,…
vfs_catia – translate illegal characters in Catia filenames Synopsis vfs objects = catia Description This VFS module is part of the samba(7) suite. The Catia CAD package commonly creates filenames that use characters that are illegal in CIFS filenames. The vfs_catia VFS module implements a character mapping so that these files can be shared with…
vfs_cap – CAP encode filenames Synopsis vfs objects = cap Description This VFS module is part of the samba(7) suite. CAP (Columbia Appletalk Protocol) encoding is a technique for representing non-ASCII filenames in ASCII. The vfs_cap VFS module translates filenames to and from CAP format, allowing users to name files in their native encoding. CAP…
vfs_cacheprime – prime the kernel file data cache Synopsis vfs objects = cacheprime Description This VFS module is part of the samba(7) suite. The vfs_cacheprime VFS module reads chunks of file data near the range requested by clients in order to make sure the data is present in the kernel file data cache at the…
vfs_btrfs – Utilize features provided by the Btrfs filesystem Synopsis vfs objects = btrfs Description This VFS module is part of the samba(8) suite. The vfs_btrfs VFS module exposes Btrfs specific features for use by Samba. Btrfs allows for multiple files to share the same on-disk data through the use cloned ranges. When an SMB…
vfs_audit – record selected Samba VFS operations in the system log Synopsis vfs objects = audit Description This VFS module is part of the samba(7) suite. The vfs_audit VFS module records selected client operations to the system log using syslog(3). The following Samba VFS operations are recorded: connect disconnect opendir mkdir rmdir open close rename…
vfs_aio_pthread – implement async I/O in Samba vfs using a pthread pool Synopsis vfs objects = aio_pthread Description This VFS module is part of the samba(7) suite. The aio_pthread VFS module enables asynchronous I/O for Samba on platforms which have the pthreads API available, without using the Posix AIO interface. Posix AIO can suffer from…
vfs_aio_linux – implement async I/O in Samba vfs using Linux kernel aio calls Synopsis vfs objects = aio_linux Description This VFS module is part of the samba(7) suite. The aio_linux VFS module enables asynchronous I/O for Samba on Linux kernels that have the kernel AIO calls available without using the Posix AIO interface. Posix AIO…
vfs_aio_fork – implement async I/O in Samba vfs Synopsis vfs objects = aio_fork Description This VFS module is part of the samba(7) suite. The aio_fork VFS module enables async I/O for Samba on platforms where the system level Posix AIO interface is insufficient. Posix AIO can suffer from severe limitations. For example, on some Linux…
vfs_acl_xattr – Save NTFS-ACLs in Extended Attributes (EAs) Synopsis vfs objects = acl_xattr Description This VFS module is part of the samba(7) suite. The vfs_acl_xattr VFS module stores NTFS Access Control Lists (ACLs) in Extended Attributes (EAs). This enables the full mapping of Windows ACLs on Samba servers. The ACLs are stored in the Extended…
vfs_acl_tdb – Save NTFS-ACLs in a tdb file Synopsis vfs objects = acl_tdb Description This VFS module is part of the samba(7) suite. The vfs_acl_tdb VFS module stores NTFS Access Control Lists (ACLs) in a tdb file. This enables the full mapping of Windows ACLs on Samba servers.
