Interesting thread.  So how would you go about fixing this?

I suspect you have to track down the vnode, znode_t and eventually 
modify one kernel buffers for znode_phys_t.  If your left with the 
decision to completely rebuild then repairing this might be the only 
choice some people may have.

I have a file system that at some point in the last week went from a directory per \
'ls -l' to a  special character device. This results in not being able to get into \
the file system. Here is my file system, scott2, along with a new file system I  just \
created, as seen by ls -l:

drwxr-xr-x 4 root root    4 Sep 27 09:14 scott
crwxr-xr-x 9 root root 0, 0 Sep 20 11:51 scott2

Notice the 'c' vs. 'd' at the beginning of the permissions list. I had been fiddling \
with permissions last week, then had problems with a kernel panic.  </pre>

Are you still running with aok/zfs_recover being set? Have you seen this issue before \
panic?

May be.

This can be fixed, but it is a bit more complicated and error prone that setting \
couple of variables.
