From cef48f14da6eec8a9095a0272f1cd7d9d60ca476 Mon Sep 17 00:00:00 2001 From: Tom Caputi Date: Wed, 28 Nov 2018 13:12:08 -0500 Subject: [PATCH] Remove races from scrub / resilver tests Currently, several tests in the ZFS Test Suite that attempt to test scrub and resilver behavior occasionally fail. A big reason for this is that these tests use a combination of zinject and zfs_scan_vdev_limit to attempt to slow these operations enough to verify their test commands. This method works most of the time, but provides no guarantees and leads to flaky behavior. This patch adds a new tunable, zfs_scan_suspend_progress, that ensures that scans make no progress, guaranteeing that tests can be run without racing. This patch also changes zfs_remove_max_bytes_pause to match this new tunable. This provides some consistency between these two similar tunables and ensures that the tunable will not misbehave on 32-bit systems.
