[Gluster-devel] Bug Reports

[Gordan Bobic]

OK, just managed to clear this weird condition and return things to some 
appearance of normality. Stopping all the servers and explicitly 
deleting the offending symling/directory (it seems to have splitbrained 
- some servers had the symling (which wasn't viewable!) and others had 
the directory (which was also not viewable). Deleting them all from the 
backing store, and remounting seems to have fixed the problem. Really 
weird how it split-brained while all the servers were up, though. :-/
