Base init scripts for SYSV systems
* Based on the init scripts included with Debian GNU/Linux, then take code
from the already existing ones, trying to merge them into one set of
scripts that will work for 'everyone' for better maintainability.
* Add configurable variables to control the workings of the init scripts:
* ZFS_INITRD_PRE_MOUNTROOT_SLEEP
Set a sleep time before we load the module (used primarily by initrd
scripts to allow for slower media (such as USB devices etc) to be
availible before we load the zfs module).
* ZFS_INITRD_POST_MODPROBE_SLEEP
Set a timed sleep in the initrd to after the load of the zfs module.
* ZFS_INITRD_ADDITIONAL_DATASETS
To allow for mounting additional datasets in the initrd. Primarily used
in initrd scripts to allow for when filesystem needed to boot (such as
/usr, /opt, /var etc) isn't directly under the root dataset.
* ZFS_POOL_EXCEPTIONS
Exclude pools from being imported (in the initrd and/or init scripts).
* ZFS_DKMS_ENABLE_DEBUG, ZFS_DKMS_ENABLE_DEBUG_DMU_TX, ZFS_DKMS_DISABLE_STRIP
Set to control how dkms should build the dkms packages.
* ZPOOL_IMPORT_PATH
Set path(s) where "zpool import" should import pools from.
This was previously the job of "USE_DISK_BY_ID" (which is still used
for backwards compatibility) but was renamed to allow for better
control of import path(s).
* If old USE_DISK_BY_ID is set, but not new ZPOOL_IMPORT_PATH, then we
set ZPOOL_IMPORT_PATH to sane defaults just to be on the safe side.
* ZED_ARGS
To allow for local options to zed without having to change the init script.
* The import function, do_import(), imports pools by name instead of '-a'
for better control of pools to import and from where.
* If USE_DISK_BY_ID is set (for backwards compatibility), but isn't 'yes'
then ignore it.
* If pool(s) isn't found with a simple "zpool import" (seen it happen),
try looking for them in /dev/disk/by-id (if it exists). Any duplicates
(pools found with both commands) is filtered out.
* IF we have found extra pool(s) this way, we must force USE_DISK_BY_ID
so that the first, simple "zpool import $pool" is able to find it.
* Fallback on importing the pool using the cache file (if it exists) only
if 'simple' import (either with ZPOOL_IMPORT_PATH or the 'built in'
defaults) didn't work.
* The export function, do_export(), will export all pools imported, EXCEPT
the root pool (if there is one).
* ZED script from the Debian GNU/Linux packages added.
* Refreshed ZED init script from behlendorf@5e7a660 to be portable so it
may be used on both LSB and Redhat style systems.
* If there is no pool(s) imported and zed successfully shut down, we will
unload the zfs modules.
* The function library file for the ZoL init script is installed as
/etc/init.d/zfs-functions.
* The four init scripts, the /etc/{defaults,sysconfig,conf.d}/zfs config file
as well as the common function library is tagged as '%config(noreplace)' in
the rpm rules file to make sure they are not replaced automatically if locally
modifed.
* Pitfals and workarounds:
* If we're running from init, remove stale /etc/dfs/sharetab before importing
pools in the zfs-import init script.
* On Debian GNU/Linux, there's a 'sendsigs' script that will kill basically
everything quite early in the shutdown phase and zed is/should be stopped
much later than that. We don't want zed to be among the ones killed, so add
the zed pid to list of pids for 'sendsigs' to ignore.
* CentOS uses echo_success() and echo_failure() to print out status of
command. These in turn uses "echo -n \0xx[etc]" to move cursor and choose
colour etc. This doesn't work with the modified IFS variable we need to
use in zfs-import for some reason, so work around that when we define
zfs_log_{end,failure}_msg() for RedHat and derivative distributions.
* All scripts passes ShellCheck (with one false positive in do_mount()).

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.

* Debian GNU/Linux Wheezy
|

Set to control how dkms should build the dkms packages.
* ZPOOL_IMPORT_PATH
Set path(s) where "zpool import" should import pools from.
This was previously the job of "USE_DISK_BY_ID" (which is still used
for backwards compatibility) but was renamed to allow for better
control of import path(s).
* If old USE_DISK_BY_ID is set, but not new ZPOOL_IMPORT_PATH, then we
set ZPOOL_IMPORT_PATH to sane defaults just to be on the safe side.
* ZED_ARGS
To allow for local options to zed without having to change the init script.
* The import function, do_import(), imports pools by name instead of '-a'
for better control of pools to import and from where.
* If USE_DISK_BY_ID is set (for backwards compatibility), but isn't 'yes'
then ignore it.
* If pool(s) isn't found with a simple "zpool import" (seen it happen),
try looking for them in /dev/disk/by-id (if it exists). Any duplicates
(pools found with both commands) is filtered out.
* IF we have found extra pool(s) this way, we must force USE_DISK_BY_ID
so that the first, simple "zpool import $pool" is able to find it.
* Fallback on importing the pool using the cache file (if it exists) only
if 'simple' import (either with ZPOOL_IMPORT_PATH or the 'built in'
defaults) didn't work.
* The export function, do_export(), will export all pools imported, EXCEPT
the root pool (if there is one).
* ZED script from the Debian GNU/Linux packages added.
* Refreshed ZED init script from behlendorf@5e7a660 to be portable so it
may be used on both LSB and Redhat style systems.
* If there is no pool(s) imported and zed successfully shut down, we will
unload the zfs modules.
* The function library file for the ZoL init script is installed as
/etc/init.d/zfs-functions.
* The four init scripts, the /etc/{defaults,sysconfig,conf.d}/zfs config file
as well as the common function library is tagged as '%config(noreplace)' in
the rpm rules file to make sure they are not replaced automatically if locally
modifed.
* Pitfals and workarounds:
* If we're running from init, remove stale /etc/dfs/sharetab before importing
pools in the zfs-import init script.
* On Debian GNU/Linux, there's a 'sendsigs' script that will kill basically
everything quite early in the shutdown phase and zed is/should be stopped
much later than that. We don't want zed to be among the ones killed, so add
the zed pid to list of pids for 'sendsigs' to ignore.
* CentOS uses echo_success() and echo_failure() to print out status of
command. These in turn uses "echo -n \0xx[etc]" to move cursor and choose
colour etc. This doesn't work with the modified IFS variable we need to
use in zfs-import for some reason, so work around that when we define
zfs_log_{end,failure}_msg() for RedHat and derivative distributions.
* All scripts passes ShellCheck (with one false positive in do_mount()).

separate datasets like /var, are mounted before anything else is started.

Base init scripts for SYSV systems
* Based on the init scripts included with Debian GNU/Linux, then take code
from the already existing ones, trying to merge them into one set of
scripts that will work for 'everyone' for better maintainability.
* Add configurable variables to control the workings of the init scripts:
* ZFS_INITRD_PRE_MOUNTROOT_SLEEP
Set a sleep time before we load the module (used primarily by initrd
scripts to allow for slower media (such as USB devices etc) to be
availible before we load the zfs module).
* ZFS_INITRD_POST_MODPROBE_SLEEP
Set a timed sleep in the initrd to after the load of the zfs module.
* ZFS_INITRD_ADDITIONAL_DATASETS
To allow for mounting additional datasets in the initrd. Primarily used
in initrd scripts to allow for when filesystem needed to boot (such as
/usr, /opt, /var etc) isn't directly under the root dataset.
* ZFS_POOL_EXCEPTIONS
Exclude pools from being imported (in the initrd and/or init scripts).
* ZFS_DKMS_ENABLE_DEBUG, ZFS_DKMS_ENABLE_DEBUG_DMU_TX, ZFS_DKMS_DISABLE_STRIP
Set to control how dkms should build the dkms packages.

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
