…dev_validate Reviewed by: George Wilson <george.wil...@delphix.com> Reviewed by: Matt Ahrens <matthew.ahr...@delphix.com>
ztest failed with uncorrectable IO error despite having the fix for #7163. Both sides of the mirror have CANT_OPEN_BAD_LABEL, which also distinguishes it from that issue. Definitely seems like a racing condition between the vdev_validate and spa_sync: 1. Thread A (spa_sync): vdev label is updated to latest txg 2. Thread B (vdev_validate): vdev label's txg is compared to spa_last_synced_txg and is ahead. 3. Thread A (spa_sync): spa_last_synced_txg is updated to latest txg. Solution: do not check txg in vdev_validate unless config lock is held.
