Data and parity is striped across all disks within a raidz group.Ī raidz group can have single-, double-, or triple-parity, meaning that the raidz group can sustain one, two, or three failures, respectively, without losingĪny data. A mirror with N disks of size X can hold Xīytes and can withstand (N-1) devices failing before data integrity is compromised.Ī variation on RAID-5 that allows for better distribution of parity and eliminates the RAID-5 "write hole" (in which data and parity become inconsistent after a Data is replicated in an identical fashion across all components of a mirror. It is designed primarily for experimental purposes, as the fault tolerance of aįile is only as good as the file system of which it is a part. The use of files as a backing store is strongly discouraged. When given a whole disk, ZFS automatically labels the disk, if necessary.įile A regular file. For example, sda is equivalent to /dev/sda. A whole disk can be specified by omitting

Aĭisk can be specified by a full path, or it can be a shorthand name (the relative portion of the path under /dev). ZFS can use individual slices or partitions, though the recommended mode of operation is to use whole disks. The following virtualĭisk A block device, typically located under /dev. See zfs(8) for information on managing datasets.Ī "virtual device" describes a single device or a collection of devices organized according to certain performance and fault characteristics. Allĭatasets within a storage pool share the same space. A storage pool is a collection of devices that provides physical storage and data replication for ZFS datasets. The zpool command configures ZFS storage pools.
