Tony Hutter 0bc841fb59 zpool: Add slot power control, print power status
Add `zpool` flags to control the slot power to drives.  This assumes
your SAS or NVMe enclosure supports slot power control via sysfs.

The new `--power` flag is added to `zpool offline|online|clear`:

    zpool offline --power <pool> <device>    Turn off device slot power
    zpool online --power <pool> <device>     Turn on device slot power
    zpool clear --power <pool> [device]      Turn on device slot power

If the ZPOOL_AUTO_POWER_ON_SLOT env var is set, then the '--power'
option is automatically implied for `zpool online` and `zpool clear`
and does not need to be passed.

zpool status also gets a --power option to print the slot power status.

Tony Hutter dffe59c415 zed: misc vdev_enc_sysfs_path fixes
There have been rare cases where the VDEV_ENC_SYSFS_PATH value that zed
gets passed is stale.  To mitigate this, dynamically check the sysfs
path at the time of zed event processing, and use the dynamic value if
possible.  Note that there will be other times when we can not
dynamically detect the sysfs path (like if a disk disappears) and have
to rely on the old value for things like turning on the fault LED.  That
is to say, we can't just blindly use the dynamic path in every case.

Also:
	- Add enclosure sysfs entry when running 'zpool add'
	- Fix 'slot' and 'enc' zpool.d scripts for nvme

Ameer Hamza 777c98ee52 Use setproctitle to report progress of zfs send
This allows parsing of zfs send progress by checking the process
title.
Doing so requires some changes to the send code in libzfs_sendrecv.c;
primarily these changes move some of the accounting around, to allow
for the code to be verbose as normal, or set the process title. Unlike
BSD, setproctitle() isn't standard in Linux; thus, borrowed it from
libbsd with slight modifications.

Tony Hutter 2b8b89c6b3 zed: Fix mpath autoreplace on Centos 7
A prior commit included a udev check for MPATH_DEVICE_READY to
determine if a path was multipath when doing an autoreplace:

    f2f6c18 zed: Misc multipath autoreplace fixes

However, MPATH_DEVICE_READY is not provided by the older version of
udev that's on Centos 7 (it is on Centos 8).

This patch instead looks for 'mpath-' in the UUID, which works on
both Centos 7 and 8.

Tony Hutter 90abfdf8ee zed: Misc multipath autoreplace fixes
We recently had a case where our operators replaced a bad
multipathed disk, only to see it fail to autoreplace.  The
zed logs showed that the multipath replacement disk did not pass
the 'is_dm' test in zfs_process_add() even though it should have.
is_dm is set if there exists a sysfs entry for to the
underlying /dev/sd* paths for the multipath disk.  It's
possible this path didn't exist due to a race condition where
the sysfs paths weren't created at the time the udev event came
in to zed, but this was never verified.

This patch updates the check to look for udev properties that
indicate if the new autoreplace disk is an empty multipath disk,
rather than looking for the underlying sysfs entries. It also
adds in additional logging, and fixes a bug where zed allowed
you to use an already zfs-formatted disk from another pool
as a multipath auto-replacement disk.

Furthermore, while testing this patch, I also ran across a case
where a force-faulted disk did not have a ZPOOL_CONFIG_PHYS_PATH
entry in its config.  This prevented it from being autoreplaced.
I added additional logic to derive the PHYS_PATH from the PATH if
the PATH was a /dev/disk/by-vdev/ path.  For example, if PATH
was /dev/disk/by-vdev/L28, then PHYS_PATH would be L28.  This is
safe since by-vdev paths represent physical locations and do not
change between boots.

Tony Hutter 586b5d366e Rescan enclosure sysfs path on import
When you create a pool, zfs writes vd->vdev_enc_sysfs_path with the
enclosure sysfs path to the fault LEDs, like:

    vdev_enc_sysfs_path = /sys/class/enclosure/0:0:1:0/SLOT8

However, this enclosure path doesn't get updated on successive imports
even if enclosure path to the disk changes.  This patch fixes the issue.

Better zfs_get_enclosure_sysfs_path() enclosure support
A multpathed disk will have several 'underlying' paths to the disk.  For
example, multipath disk 'dm-0' may be made up of paths:
/dev/{sda,sdb,sdc,sdd}.  On many enclosures those underlying sysfs
paths will have a symlink back to their enclosure device entry
(like 'enclosure_device0/slot1').  This is used by the
statechange-led.sh script to set/clear the fault LED for a disk, and
by 'zpool status -c'.

However, on some enclosures, those underlying paths may not all have
symlinks back to the enclosure device.  Maybe only two out of four
of them might.

This patch updates zfs_get_enclosure_sysfs_path() to favor returning
paths that have symlinks back to their enclosure devices, rather
than just returning the first path.

Alan Somers fd95af8dd4
Speed up "zpool import" in the presence of many zvols
By default, FreeBSD does not allow zpools to be backed by zvols (that
can be changed with the "vfs.zfs.vol.recursive" sysctl). When that
sysctl is set to 0, the kernel does not attempt to read zvols when
looking for vdevs. But the zpool command still does. This change brings
the zpool command into line with the kernel's behavior. It speeds "zpool
import" when an already imported pool has many zvols, or a zvol with
many snapshots.

Remove unnecessary references to slavery
The horrible effects of human slavery continue to impact society.  The
casual use of the term "slave" in computer software is an unnecessary
reference to a painful human experience.

This commit removes all possible references to the term "slave".

Implementation notes:

The zpool.d/slaves script is renamed to dm-deps, which uses the same
terminology as `dmsetup deps`.

References to the `/sys/class/block/$dev/slaves` directory remain.  This
directory name is determined by the Linux kernel.  Although
`dmsetup deps` provides the same information, it unfortunately requires
elevated privileges, whereas the `/sys/...` directory is world-readable.

Richard Yao 803884217f Implement ZPOOL_IMPORT_UDEV_TIMEOUT_MS
Since 0.7.0, zpool import would unconditionally block on udev for 30
seconds. This introduced a regression in initramfs environments that
lack udev (particularly mdev based environments), yet use a zfs userland
tools intended for the system that had been built against udev. Gentoo's
genkernel is the main example, although custom user initramfs
environments would be similarly impacted unless special builds of the
ZFS userland utilities were done for them.  Such environments already
have their own mechanisms for blocking until device nodes are ready
(such as genkernel's scandelay parameter), so it is unnecessary for
zpool import to block on a non-existent udev until a timeout is reached
inside of them.

Rather than trying to intelligently determine whether udev is available
on the system to avoid unnecessarily blocking in such environments, it
seems best to just allow the environment to override the timeout.  I
propose that we add an environment variable called
ZPOOL_IMPORT_UDEV_TIMEOUT_MS. Setting it to 0 would restore the 0.6.x
behavior that was more desirable in mdev based initramfs environments.
This allows the system user land utilities to be reused when building
mdev-based initramfs archives.
