I have a software RAID setup in Windows Server 2003, which recently had a disk go bad. I replaced the disk, and rebuilt the array. Every time I reboot though, it automatically starts rebuilding the array. The resynching slows disk access down to a crawl, so is there a way to stop or pause it. I have 1 RAID 5, and 2 separate Mirrors, and its trying to resynch all 3 arrays at the same time. This basically makes my bootup time over 48 hours! I'd like to postpone the array rebuilds until after I copy all my precious data off it.
Caveat -- this is not for a RAID 5, but for a RAID 1. Hopefully, it also applies to RAID 5, to remove the drive being synchronized. In any case, it is wisdom to perform an image-level backup before doing anything.
Select the disk that is not good yet, right click on its mirrored volume, and choose "Remove Mirror..." from the menu.
When it asks which disk, choose the disk not yet synchronized (shown by warning triangle), and click "Remove Mirror":
This should stop the synchronization process and allow you to copy the files off of the drive. The end state should look like this:
That's it. HTH.
