Overview & More informations

ZFS on Linux (ZoL) is an open-source project that aims to bring the Zettabyte File System (ZFS) to the Linux operating system. ZFS is a powerful file system that was originally developed by Sun Microsystems and is now maintained by Oracle. It is known for its features such as data integrity, high availability, and scalability.

The ZoL project provides a set of kernel modules and user-space utilities that allow ZFS to be used on Linux systems. ZoL is compatible with a wide range of Linux distributions, including Ubuntu, CentOS, and Fedora.

One of the main benefits of using ZFS on Linux is its data integrity features. ZFS uses a copy-on-write mechanism to ensure that data is never overwritten accidentally. It also uses checksums to verify the integrity of data both on disk and in memory. This makes ZFS very resistant to data corruption.

Another benefit of ZFS is its high availability features. ZFS can be configured to use multiple disks in a redundant array, which ensures that data is still available even if one or more disks fail. ZFS also supports online repairs, which means that data can be repaired without having to take the file system offline.

Finally, ZFS is a very scalable file system. It can be used to manage large amounts of data, even on very large systems. ZFS also supports a variety of features that can help to improve performance, such as compression and deduplication.

Overall, ZFS on Linux is a powerful and versatile file system that can be used to improve the performance, reliability, and scalability of Linux systems.
