 Description   
i see these crashes after resetting the data path to /data which had data files from build with a different file format ( or let's say the file could be corrupted )

i am not sure what we can do in this case - keep the server running but show that the status is yellow for that node ?

i think this is not a blocker or even major becasue we wont have users with earlier builds and we will keep data files compatible between 2.0 versions.

Having any logs here would be actually very helpful
Comment by Karen Zeller [ 06/Dec/12 ]
Added to RN:

If you reset the disk path to a path that contained corrupted data, Couchbase
Server will shut down and non response. Avoid using the same data path if had
contained corrupted data.
