I'm a bit confused. I tried hard, but haven't been able to reproduce this using Sol10U8. I have a mirrored slog device. While putting it under load doing synchronous file creations, we pulled the power cords and unplugged the slog devices. After powering on zfs imported the pool, but prompted to acknowledge the missing slog devices with zpool clear. After that the pool was accessible again. That's exactly how it should be. What am I doing wrong here? The system is on a different pool using different disks. One peculiarity I noted though: when pulling both slog devices from the running machine, zpool status reports 1 file error. In my understanding this should not happen as the file data is written from memory and not from the contents of the zil. It seems the reported write error from the slog device somehow lead to a corrupted file.
