10900 Fix estimated scrub completion time

illumos/illumos-gate@3db6627c6730f7ec4426ac0be0e9338235aed2d8 https://github.com/illumos/illumos-gate/commit/3db6627c6730f7ec4426ac0be0e9338235aed2d8 https://www.illumos.org/issues/10900 ZoL update: Author: Tom Caputi Date: Wed May 1 20:34:24 2019 -0400 Fix estimated scrub completion time Currently, it is possible for the 'zpool scrub' command to progress slightly beyond 100% due to concurrent changes happening on the live pool. This behavior is expected, but the userspace code for 'zpool status' would subtract the expected amount of data from the amount of data already scrubbed, resulting in a negative integer being casted to a large positive one. This number was then used to calculate the estimated completion time, resulting in wildly wrong results. This code changes the behavior so that 'zpool status' does not attempt to report an estimate during this period. Reviewed by: Brian Behlendorf Reviewed-by: Igor Kozhukhov Reviewed-by: George Melikov Signed-off-by: Tom Caputi Closes #8611 Closes #8687 After this fix, the zpool status output does display more reasonable output.

10566 Multiple DVA Scrubbing Fix

2019-11-21T14:00:09Z

illumos/illumos-gate@12a8814c13fbb1d6d58616cf090ea5815dc107f9 https://github.com/illumos/illumos-gate/commit/12a8814c13fbb1d6d58616cf090ea5815dc107f9 https://www.illumos.org/issues/10566 ZoL PR_8453 Author: Tom Caputi Date: Fri Mar 15 17:14:31 2019 -0400 Multiple DVA Scrubbing Fix Currently, there is an issue in the sequential scrub code which prevents self healing from working in some cases. The scrub code will split up all DVA copies of a bp and issue each of them separately. The problem is that, since each of the DVAs is no longer associated with the others, the self healing code doesn't have the opportunity to repair problems that show up in one of the DVAs with the data from the others. This patch fixes this issue by ensuring that all IOs issued by the sequential scrub code include all DVAs. Initially, only the first DVA of each is attempted. If an issue arises, the IO is retried with all available copies, giving the self healing code a chance to correct the issue. To test this change, this patch also adds the ability for zinject to specify individual DVAs to inject read errors into. We then add a new test case that utilizes this functionality to ensure scrubs and self-healing reads can handle and transparently fix issues with individual copies of blocks. This update is followup on #10405 While attempting to port this update, the following ZoL updates are included: 551905dd4 vdev_mirror: kstat observables for preferred vdev d6c6590c5 vdev_mirror: load balancing fixes 9f500936c FreeBSD r256956: Improve ZFS N-way mirror read performance by Portions contributed by: Toomas Soome Portions contributed by: Jerry Jelinek Author: Tom Caputi

Here is the original description. This addition will enable us to sync an open TXG to the main pool on demand. The functionality is similar to 'sync(2)' but 'zpool sync' will return when data has hit the main storage instead of potentially just the ZIL as is the case with the 'sync(2)' cmd.
