ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
The ZFS file system was originally developed by Sun Microsystems for the Solaris operating system. The ZFS source code was released in 2005 under the Common Development and Distribution License as part of the OpenSolaris operating system, and it was later ported to other operating systems and environments.
z/OS File System (zFS) (official name: z/OS® Distributed File Service zSeries® File System) is a POSIX-style hierarchical file system for IBM's z/OS operating system for z System mainframes, a successor to that operating system's HFS.
Oracle ZFS is Oracle's proprietary implementation of the ZFS file system and logical volume manager for Oracle Solaris. ZFS is a registered trademark belonging to ...
MDTs and OSTs currently use either an enhanced version of ext4 called ldiskfs, or ZFS/DMU for back-end data storage to store files/objects [85] using the open source ZFS-on-Linux port. [86] The client mounts the Lustre filesystem locally with a VFS driver for the Linux kernel that connects the client to the server(s).
Lustre Cluster filesystem will use FUSE to allow it to run in userspace, so that a FreeBSD port is possible. [11] However, the ZFS-Linux port of Lustre will be running ZFS's DMU (Data Management Unit) in userspace. [12] MinFS: MinFS is a fuse driver for Amazon S3 compatible object storage server.
Proxmox Backup Server (short Proxmox BS) is an open-source backup software project supporting virtual machines, containers, and physical hosts. [3] The Bare-metal server is based on the Debian Linux distribution, with some extended features, such as out-of-the-box ZFS support and Linux kernel 5.4 LTS. [4]
In addition to handling whole-disk failures, RAID-Z can also detect and correct silent data corruption, offering "self-healing data": when reading a RAID-Z block, ZFS compares it against its checksum, and if the data disks did not return the right answer, ZFS reads the parity and then figures out which disk returned bad data. Then, it repairs ...
