RAID 1 software mirror
Posted on 2013-01-02
I have issues setting up a RAID 1 mirror through Disk Manager, as a software RAID to have fault tolerance, along with my present windows server backups.
I have two Seagate 1 TB drives, the only difference is that one is a model 524, and the other is a 528.
Both are not advanced format, otherwise it would dis-allow.
When I go to mirror the primary disk (disk 0) which containes the volumes: System Reserved, and C: , it will SUCCESSFULLY mirror the System Reserved (shows healthy), and when mirroring the C: volume, it will show "Resynching".
The new drive (disk 1) will have a yellow exlamation as well.
I have to refresh from time to time to monitor the progress, but takes a while. I will usually come back to it, and it will show: "Failed Redundancy" each time. I am unsure what could be the issue. Both drives are plugged in straight to the mobo sata slot 1 and 2, so no other H/W, or the like. Both drives have write caching disabled.
The C: volume is around 931 GB. I downloaded Seatools, ran a error check on both, SMART on both, and DST on both and came out perfect. No fragmentation.
I am out of ideas? Is this an issue with server 2012 perhaps?
