![]() ![]() To make a mirrored storage pool, use the following command syntax: $ sudo zpool create mypool mirror /dev/sdb /dev/sdc. This gives you redundancy because all your data is mirrored from one hard disk to one or more others. 5.Software RAID.Ī mirrored storage pool is ZFS' equivalent to RAID 1. 2.ZFS snapshots,clones and Sending-receiving snapshots. ZFS quick command reference with examples. The snapshot uses only space when the block references are changed. Snapshot is one of the most powerfull features of ZFS, a snapshot provides a read-only, point-in-time copy of a file system or volume that does not consume extra space in the ZFS pool. If you disable this property, you can use the zfs list -t snapshot command to display snapshot information. You can enable or disable the display of snapshot listings in the zfs list output by using the listsnapshots pool property. ![]() Snapshots save disk space by recording only the differences between the current dataset and a previous version.ĭisplaying and Accessing ZFS Snapshots. The snapshot only uses space when the block references are changed. The snapshotname is specified as follows: The snapshot name must satisfy the naming requirements in ZFS Component Naming Requirements.Ī snapshot provides a read-only point-in-time copy of a file system or volume that does not consume extra space in the ZFS pool. Snapshots are created by using the zfs snapshotor the zfs snapcommand, which takesas its only argument the name of the snapshot to create. ZFS was revolutionary for completely decoupling the file system from specialized storage hardware and even a specific computer platform. OPENZFS V5000 CODEThis repository contains the code for running OpenZFS on Linux and FreeBSD.įrom its inception, “ ZFS ” has referred to the “Zettabyte File System” developed at Sun Microsystems and published under the CDDL Open Source license in 2005 as part of the OpenSolaris operating system. OpenZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the OpenZFS community. OpenZFS is a project started by many of the original ZFS developers to create an open source implementation of ZFS. OpenZFS is more than a file system since it also includes volume management, integrity checking, self-healing, built-in RAID, almost inconceivably large theoretical capacity (256 trillion yobibytes is claimed), transparent compression, native encryption, and storage and replication. The OpenZFS project is an open source derivative of the Oracle ZFS project. Founding members of OpenZFS include Matt Ahrens, one of the main architects of ZFS. ![]() The eponymous OpenZFS project brings together developers from the illumos, Linux, FreeBSD and macOS platforms, and a wide range of companies via the annual OpenZFS Developer Summit.

These two open source licenses are not fully compatible with each other. ZFS is open source under Common Development and Distribution License (CDDL) 1.0 whereas Linux kernel is licensed under the GNU General Public License (GPL) 2.0. In this guide, we learned about some basic usage commands for ZFS in Ubuntu 20.04 Focal Fossa. It's perfect for storage/NAS servers and any environment where read and write speeds are crucial along with hard drive redundancy. ZFS is a file system focused on high availability and data integrity. ![]()
