| # Installation | ||
|
|
||
| Full documentation for installing ZoL on your favorite Linux distribution can | ||
| be found at [our site](http://zfsonlinux.org/). | ||
| ZoF is available in the FreeBSD ports tree as sysutils/openzfs and | ||
| sysutils/openzfs-kmod. It can be installed on FreeBSD stable/12 or later. | ||
|
|
||
| # Contribute & Develop | ||
| # Branches | ||
|
|
||
| We have a separate document with [contribution guidelines](./.github/CONTRIBUTING.md). | ||
| * projects/zfsbsd - stable branch used by the port | ||
| * projects/pr-rebase-* - development branch, frequently rebased on ZoL master | ||
| * projects/pr-rebase - squashed development branch for the ZoL PR | ||
|
|
||
| # Release | ||
| We frequently rebase the development branch on ZoL master to keep up with | ||
| upstream changes, creating a new branch to preserve the commit history in case | ||
| of mismerges and to avoid force pushes. | ||
|
|

| For more details see the NOTICE, LICENSE and COPYRIGHT files; `UCRL-CODE-235197` | ||
| # Development | ||
|
|
||
| The following dependencies are required to build ZoF from source: | ||
| * FreeBSD sources (in /usr/src or elsewhere specified by passing | ||
| `--with-freebsd=$path` to `./configure` | ||
| * Packages for build: | ||
| ``` | ||
| autoconf | ||
| automake | ||
| autotools | ||
| bash | ||
| git | ||
| gmake | ||
| ``` | ||
| * Optional packages for build: | ||
| ``` | ||
| python3 # or your preferred Python version | ||
| ``` | ||
| * Optional packages for test: | ||
| ``` | ||
| base64 | ||
| fio | ||
| hs-ShellCheck | ||
| ksh93 | ||
| py36-flake8 # or your preferred Python version | ||
| shuf | ||
| sudo | ||
| ``` | ||
| The user for running tests must have NOPASSWD sudo permission. | ||
|
|
||
| To build and install: | ||
| ``` | ||
| # as user | ||
| git clone https://github.com/zfsonfreebsd/ZoF | ||
| cd ZoF | ||
| ./autogen.sh | ||
| ./configure | ||
| gmake | ||
| # as root | ||
| gmake install | ||
| ``` | ||
| The ZFS utilities will be installed in /usr/local/sbin/, so make sure your PATH | ||
| gets adjusted accordingly. Though not required, `WITHOUT_ZFS` is a useful build | ||
| option to avoid installing legacy zfs tools and kmod - see `src.conf(5)`. | ||
|
|
||
| Beware that the FreeBSD boot loader does not allow booting from root pools with | ||
| encryption active (even if it is not in use), so do not try encryption on a | ||
| pool you boot from. | ||

| * Functions to convert between a list of vdevs and an nvlist representing the | ||
| * configuration. Each entry in the list can be one of: | ||
| * | ||
| * Device vdevs | ||
| * disk=(path=..., devid=...) | ||
| * file=(path=...) | ||
| * | ||
| * Group vdevs | ||
| * raidz[1|2]=(...) | ||
| * mirror=(...) | ||
| * | ||
| * Hot spares | ||
| * | ||
| * While the underlying implementation supports it, group vdevs cannot contain | ||
| * other group vdevs. All userland verification of devices is contained within | ||
| * this file. If successful, the nvlist returned can be passed directly to the | ||
| * kernel; we've done as much verification as possible in userland. | ||
| * | ||
| * Hot spares are a special case, and passed down as an array of disk vdevs, at | ||
| * the same level as the root of the vdev tree. | ||
| * | ||
| * The only function exported by this file is 'make_root_vdev'. The | ||
| * function performs several passes: | ||
| * | ||
| * 1. Construct the vdev specification. Performs syntax validation and | ||
| * makes sure each device is valid. | ||
| * 2. Check for devices in use. Using libdiskmgt, makes sure that no | ||
| * devices are also in use. Some can be overridden using the 'force' | ||
| * flag, others cannot. | ||
| * 3. Check for replication errors if the 'force' flag is not specified. | ||
| * validates that the replication level is consistent across the | ||
| * entire pool. | ||
| * 4. Call libzfs to label any whole disks with an EFI label. | ||
