Before allowing the ZED to mark a vdev as REMOVED due to a
hotplug event confirm that it is non-responsive with probe.
Any device which can be successfully probed should be left
ONLINE to prevent a healthy pool from being incorrectly
SUSPENDED. This may occur for at least the following two
scenarios.
1) Drive expansion (zpool online -e) in VMware environments.
If, during the partition resize operation, a partition is
removed and re-created then udev will send a removed event.
2) Re-scanning the namespaces of an NVMe device (nvme ns-rescan)
may result in a udev remove and add event being delivered.
Finally, update the ZED to only kick in a spare when the

When resilvering the estimated time remaining is calculated using
the average issue rate over the current pass. Where the current
pass starts when a scan was started, or restarted, if the pool
was exported/imported.
For dRAID pools in particular this can result in wildly optimistic
estimates since the issue rate will be very high while scanning
when non-degraded regions of the pool are scanned. Once repair
I/O starts being issued performance drops to a realistic number
but the estimated performance is still significantly skewed.
To address this we redefine a pass such that it starts after a
scanning phase completes so the issue rate is more reflective of
recent performance. Additionally, the zfs_scan_report_txgs
module option can be set to reset the pass statistics more often.

When scrubbing/resilvering a pool it can be counter productive to
cancel the scan and kick of a replace operation to a hot spare
when encountering checksum errors. In this case, the best course
of action is to allow the scrub/resilver to complete as quickly
as possible and to keep the vdevs fully online if possible.
Realistically, this is less of an issue for a RAIDZ since a
traditional resilver must be used and checksums will be verified.
However, this is not the case for a mirror or dRAID pool which is
sequentially resilvered and checksum verification is deferred
until after the replace operation completes.
Regardless, we apply this policy to all pool types since it's
a good idea for all vdevs. Degrading additional vdevs has the
potential to make a bad situation worse. Note the checksum
errors will still be reported as both an event and by
`zpool status`. This change only prevents the ZED from
proactively taking any action.
