I'm not sure if stuff is mirrored in single user mode. But I would resist breaking a mirror if I didn't need to. And I don't see how that will help here.
Actually, I now think that you simply had a typo in /etc/vfstab. Someone had changed /var to "ro". Later, a reboot caused your problem to occur.

As for "fsck -n", it simply provides information and I try to gather information when I don't understand something. "fsck -n" might result in anything from "all looks cool" to "file system? what file system?". Knowing the state of /var would be a help. If I'm right about the typo in /etc/fstab, "fsck -n" will not find a problem. That would lead me to stop looking at /var. Add that to the odd read-only status of /var and my next step would be to check vfstab.
I also like to run "fsck -n" to see how bad stuff is before I run a plain "fsck". I have deeply regretted not doing that on several occasions.

I appreciate the thought on vfstab. I have found an error in another server's vfstab so there's a chance that was it. I'll check the explorer output.
I've spent a lot of time these past several months discovering problems, making repairs and whipping up scripts so they won't happen again so it wouldn't surprise me.
Thanks.
