Although btrfs/143 has a similar problem, this method doesn't work for it. Unlike btrfs/142, the second IO error needs to be triggered by another process, not by xfs_io. So we can't simply set task-filter to solve this problem. I'm still investigating a way to solve the problem. Do you have any ideas? Any help will be greatly appreciated. -- Thanks, Lu -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
