I came in to find a server down. When restarting it I would get an error
message that a pool has problems and was being put in maintenance mode.
After a poolrebuild I was able to mount the volume. 1 folder (off the
root of the volume) is now missing. I can restore the files from tape but
when I try to recreate the folder I get a message that the folder already
exists. I can the same result with Windows Explorer, nwadmin, and toolbox.

How do I get past this?
