I got reply from quite a few people on this topic, some expressed interest in this topic, some offered ideas about how to go about testing. I'd like to thank all of them: Rami Aubourg Mike Ekholm Christopher L. Barnard Jaime Menendez Bertrand_Hutin Ivan Wong doberman000@ sympatico.ca Gordon Cormack Thomas_J_Jones@ eFunds.Com Galen Johnson A few suggested that I can just use system tools to observe the mirroring in action. For example, create some activity on the system and then start iostat to make sure both drives have the similar i/o. While this is going on, unplug one of the drive and see if the system will remain up. I have not yet tested this yet, but it sounds a little risky. I am concerned about damaging the disks. On some system, you can safely quiescence the disk IO first, but on a Netra T1, I am not sure. Other suggested that at the minimum, I should test breaking the mirror and re-connect the mirror to see if things gets sync'ed up. As you would have expected, this is not a problem at all. One reply also suggested that I disconnect the primary drive and verify that the system is bootable from the mirror. Remove one of the drive, add a new drive and make sure the new drive can be rebuilt. The second part of this, I believe, can be done using "metareplace". Zaigui Y!
