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.
This worked well when a single entity controlled the development of ZFS, and this versioning scheme is still in use with the ZFS in Oracle Solaris. [85] [86] In a more distributed development model, having a single version number is far from ideal as all implementations of OpenZFS would need to agree on all changes to the on-disk file system ...
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 ...
The ZFS filesystem was designed to immediately write data to a sector that reports as bad or takes an excessively long time to read (such as non-TLER drives); this will usually force an immediate sector remap on a weak sector in most drives. [citation needed]
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).
ZFS – Has checksums for all data; important metadata is always redundant, additional redundancy levels are user-configurable; copy-on-write and transactional writing ensure metadata consistency; corrupted data can be automatically repaired if a redundant copy is available.
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]
The hope was due to Stratis configuration daemon being in userland, it would more quickly reach maturity versus the years of kernel level development of file systems ZFS and Btrfs. [ 2 ] [ 3 ] It is built upon enterprise-tested components LVM and XFS with over a decade of enterprise deployments and the lessons learned from System Storage ...
