DESCRIPTION
These script were written with the primary intention of being portable and
usable on as many systems as possible.
This is, in practice, usually not possible. But the intention is there.
And it is a good one.
They have been tested successfully on:
* Debian GNU/Linux Bookworm
* Gentoo
SUPPORT
If you find that they don't work for your platform, please report this
at the OpenZFS issue tracker at https://github.com/openzfs/zfs/issues.
Please include:
* Distribution name
* Distribution version
* Where to find an install CD image
* Architecture
If you have code to share that fixes the problem, that is much better.
But please remember to try your best keep portability in mind. If you
suspect that what you're writing/modifying won't work on anything else
than your distribution, please make sure to put that code in appropriate
if/else/fi code.
It currently MUST be bash (or fully compatible) for this to work.
If you're making your own distribution and you want the scripts to
work on that, the biggest problem you'll (probably) have is the part
at the beginning of the "zfs-functions" file which sets up the
logging output.
INSTALLING INIT SCRIPT LINKS
To setup the init script links in /etc/rc?.d manually on a Debian GNU/Linux
(or derived) system, run the following commands (the order is important!):
update-rc.d zfs-import start 07 S . stop 07 0 1 6 .
update-rc.d zfs-load-key start 02 2 3 4 5 . stop 06 0 1 6 .
update-rc.d zfs-mount start 02 S . stop 06 0 1 6 .
update-rc.d zfs-zed start 07 2 3 4 5 . stop 08 0 1 6 .
update-rc.d zfs-share start 27 2 3 4 5 . stop 05 0 1 6 .
To do the same on RedHat, Fedora and/or CentOS:
chkconfig zfs-import
chkconfig zfs-load-key
chkconfig zfs-mount
chkconfig zfs-zed
chkconfig zfs-share
On Gentoo:
rc-update add zfs-import boot
rc-update add zfs-load-key boot
rc-update add zfs-mount boot
rc-update add zfs-zed default
rc-update add zfs-share default
The idea here is to make sure all of the ZFS filesystems, including possibly
separate datasets like /var, are mounted before anything else is started.
Then, ZED, which depends on /var, can be started. It will consume and act
on events that occurred before it started. ZED may also play a role in
sharing filesystems in the future, so it is important to start before the
'share' service.
Finally, we share filesystems configured with the share\* property.
