NAME
datasets - Oracle Solaris ZFS dataset organization
DESCRIPTION
Oracle Solaris is installed to a hierarchical set of ZFS datasets with
well-defined names. The ZFS datasets, composed of both file systems and
volumes, are stored on a bootable ZFS storage pool in the global zone.
Snapshots are also ZFS datasets, but will not be discussed here.
The datasets are created automatically by one of the installation
tools: the automated installer or the text installer. For non-global
zones, the datasets are created by the zone brand during the zone in‐
stallation and might differ from the hierarchy described here, which
applies to the solaris(7) brand and the global zone.
rpool Dataset
rpool is the default name of the top-level dataset in the bootable ZFS
storage pool and is mounted at /rpool. Bootable ZFS storage pools have
certain restrictions over normal ZFS storage pools. These restrictions
are discussed in the book Managing ZFS File Systems in Oracle Solaris
11.4.
Administrators can create datasets anywhere beneath the top-level
dataset, but those created within the 'ROOT/be-<name>' dataset are
treated specially by beadm(8) and are discussed later.
ROOT Dataset
This is a container dataset which is not mounted by Solaris during op‐
eration. It collects sets of related datasets, each set forming a ZFS
Boot Environment (BE). A initial BE is created on installation. Addi‐
tional BEs may be created by pkg(1). BEs can be created, modified, or
destroyed by beadm(8).
In the global zone, the ROOT dataset must be stored within a bootable
ZFS storage pool, called 'rpool' by default. For non-global zones, the
ROOT dataset is stored in a dataset with the leaf name 'rpool' beneath
the zonepath of each zone.
The list below shows the datasets that are created beneath the ROOT
dataset. This list uses the default storage pool name.
rpool/ROOT/solaris
This is the default dataset that is created for the first boot en‐
vironment installed on the system. It contains the root file system
and is mounted on '/'.
The name of the leaf component of this dataset corresponds to the
name of the BE that is associated with it. Any datasets created by
the administrator as children of the 'ROOT/<be-name>' dataset will
be associated with that BE, and will be created, cloned, destroyed,
and have snapshots taken of them as part of the BE by beadm. New
datasets created beneath 'ROOT/<be-name>' should have the zfs prop‐
erty 'canmount=noauto' set so that the datasets are mounted by
beadm when appropriate.
All packaged content that is part of the image in a boot environ‐
ment must fully reside within the datasets belonging to the boot
environment.
rpool/ROOT/solaris/var
This is a dataset associated with each boot environment that con‐
tains the /var file system for the BE.
Dump Dataset
rpool/dump is a ZFS volume created during installation and is used as
the default dump device for the system crash dump facility. This
dataset is shared across all BEs. The crash dump facility can be man‐
aged with dumpadm(8) and the dump device can be resized using zfs(8).
The dumpadm command can be used to configure other devices to be used
instead of rpool/dump, including a swap device. As the system crash
dump is generated from the kernel running in the global zone, the
rpool/dump dataset is not present on non-global zones, and dumpadm can‐
not be used to change dump configuration in a non-global zone.
Swap Dataset
rpool/swap is a ZFS zvol created during installation and is used as the
default swap area for the system. This dataset is shared across all
BEs. Use swap(8) to add or remove swap volumes. Use zfs to resize swap
volumes. The rpool/swap dataset is not present on non-global zones.
Other swap volumes can be used instead, as well as rpool/swap.
rpool/VARSHARE
rpool/VARSHARE is a dataset created on installation or upgrade, and is
not part of any one BE. Instead, it is shared across all BEs and is
mounted automatically by that BE during boot. It contains unpackaged
content from /var. For example, audit information is stored in /var/au‐
dit, core files are stored in /var/cores, saved crash dumps are stored
in /var/crash, and system mail is stored in /var/mail.
rpool/VARSHARE is reserved for use by Oracle Solaris. Creating datasets
beneath rpool/VARSHARE is not supported.
rpool/VARSHARE/zones
rpool/VARSHARE/zones is a dataset associated with each boot environment
which is mounted at /system/zones and is the default parent of zonepath
datasets.
rpool/export/home
rpool/export/home is a dataset created on installation which can be
used for user home directories. It is the default location for user
home directories if the -d option is not passed to useradd(8) to spec‐
ify a different directory. If the user home directory does not already
exist and the parent directory is the mount point of a ZFS dataset (for
example, rpool/export/home), then a child of that dataset will be cre‐
ated and mounted at the specified location. These datasets are shared
across all BEs.
