Failed Redundancy
First off - Windows 10 1709 fully patched.
I have two 2TB disks in a Windows software Raid 1 array. They are initialized as Dynamic. The last time I looked at Disk Management it informed me that they had 'Failed Redundancy'. I have a pretty good idea of what that means, but I can't find anywhere where it tells me what I should do about it. Anytime I look on line it starts giving examples and fixes for Windows Server 2012, which doesn't do me a lot of good. What exactly does 'Failed Redundancy' mean. I know it means they are no longer in sync, but does it mean the system is writing to one and not the other? Or that at one time a write didn't take place to one of the pair, and now Windows can't guarantee that everything is exact? If Windows is only writing to one, which one? Is there something I can diagnose that will help me figure out what is going on? I know that worst case I can back up the drive(s) to another disk, break the Raid, reinitialize both drives after testing the hell out of them, then reload the backup and hope everything is ok. Since backing up the drive to an external disk takes about 16hrs, I would rather not take that path. Do I have any other options? |
