Systems per system is likely to be numerous. The file system that the clone was created from.Ĭreating a ZFS file system is a simple operation, so the number of file This causes the "origin" file system to become aĬlone of the specified file system, which makes it possible to destroy The clone parent-child dependency relationship can be reversed by using Property exposes this dependency, and the destroy command lists any such Nal snapshot cannot be destroyed as long as a clone exists. The clone is created somewhere else in the dataset hierarchy, the origi. When a snapshot is cloned, itĬreates an implicit dependency between the parent and child. Nearly instantaneous, and initially consumes no additional space.Ĭlones can only be created from a snapshot.
zfs directory can be controlled by the snapdir property.Ī clone is a writable volume or file system whose initial contents are Snapshots are automatically mounted onĭemand and may be unmounted at regular intervals. Rolled back, but cannot be accessed independently.įile system snapshots can be accessed under the. As data within the active dataset changes, the snapshotĬonsumes more data than would otherwise be shared with the active Snapshots canīe created extremely quickly, and initially consume no additional space See zpool(8) for more information on creating and administering pools.Ī snapshot is a read-only copy of a file system or volume. Storage characteristics, however, are managed by the zpool(8) command. The root of the pool can be accessed as a file system, such as mountingĪnd unmounting, taking snapshots, and setting properties. A storage pool is also the root of the ZFS file system It is specified as File System HierarchyĪ ZFS storage pool is a logical collection of devices that provide spaceįor datasets. Snapshot A read-only version of a file system or volume at a given File systems are typically used in most environ. Type of dataset should only be used under special circum.
Volume A logical volume exported as a raw or block device. Might fail due to nonstandard behavior when checking file Applications that depend on standards conformance Pliant, known issues exist that prevent compliance in someĬases. While ZFS file systems are designed to be POSIX com. Standard system namespace and behaves like other file sys. Where the maximum length of a dataset name is MAXNAMELEN (256 bytes).įile system A ZFS dataset of type filesystem can be mounted within the A dataset is identified by a unique path within The zfs command configures ZFS datasets within a ZFS storage pool, asĭescribed in zpool(8).
