Quoting "Jason J. W. Williams" <jasonjwwilliams@gmail.com> (from Thu, 2 Sep 2010 13:30:51 -0600): > How well does ZFS on FreeBSD handle a dying/wedged log and/or cache > device? OpenSolaris handles this pretty well in my experience and will > fail through relatively quickly. But this tends to rely on FMA. Thank > you in advance. No problem for the cache device. I have an USB memory stick as a cache device, and if I just remove it during operation, the system handles the situation. If you connect it again, you need to remove/readd it via zfs commands. I do not use a log device. Bye, Alexander. -- Govern a great nation as you would cook a small fish.
