I have walked into a new customer site. The 2000 server they have was never promoted to a DC, so this is still a member server. There is a mirrored drive that has been setup and it is full, why would this happen? The Hard drive space on the other drive isn't at capacity yet. There are 3 volumes created and I'm wondering if that is why it is causing this. b/c the sys volume and the vol1 volume are one disk and the backup volume(mirrored drive) is the other hard disk and can't handle the data. have I solved my own question or is it something else?
