Veritas volume manager 3.510/25/2022 Version 9 enables support for file compression, deduplication, and partition directories.Version 8 enables support for file-level snapshots and shared extents.Dynamic Storage Tiering allows root users to move files among different volumes, allocate files to different volumes at file creation time based on policy, and independently recover volumes, without altering the namespace of the file system. Version 7 extends support for multiple volumes to permit Dynamic Storage Tiering.Version 6 also introduced support for named streams/resource forks, for multiple underlying volumes, and for file change logs. Version 6 added support for file systems and files up to 8 exabytes ( 2 63 bytes) in size.Version 5 was introduced in VxFS 3.5 and is no longer supported under VxFS 5.1. Individual files can be up to 2 terabytes in size. Version 5 started support for file systems up to 32 terabytes ( 2 45 bytes) in size.Layout version 4 is no longer supported under VxFS 5.1. Version 4 added support for storage checkpoints and for Veritas Cluster File System.Layouts 1-3 stopped being supported in VxFS 4.0. Version 2 added support for filesets, dynamic inode allocation and ACLs.This file system has gone through ten versions. The on-disk layout of VxFS is versioned and upgradeable while the file system is mounted. Īs the internet was not widely available in the early 1990s, getting a new file system deployed for Unix-like operating systems was more difficult, so the one- to two-year delay in the release and commercialization of this file system was not unusual. Other sources agree that the product was first released in 1991. He notes in a mailing list that they "finished release 1.0 one year or so later" after starting development of VxFS under a contract with AT&T Corporation in 1990. That claim can be taken in two ways, i.e., the first implementation of a journaling file system in a commercial context, or the first file system available as an unbundled product.ĭan Koren is cited as one of the original developers of VxFS. VxFS is packaged as a part of the Veritas Storage Foundation (which also includes Veritas Volume Manager).Īccording to the vendor, it was the first commercial journaling file system. VxFS was originally developed for AT&T's Unix System Laboratories. It is also supported on AIX, Linux, Solaris, OpenSolaris, SINIX/Reliant UNIX, UnixWare and SCO OpenServer. With on-line defragmentation and resize support turned on via license, it is known as OnlineJFS. Through an OEM agreement, VxFS is used as the primary filesystem of the HP-UX operating system. It was originally developed by VERITAS Software. The VERITAS File System (or VxFS called JFS and OnlineJFS in HP-UX) is an extent-based file system. Linux, Solaris, HP-UX, AIX, SINIX, UnixWare Not to be confused with the file systems XFS and JFS.
