Description of problem:
If maximum file size to be cached is lesser than the minimum file size to be cached, then io-cache reconfigure will set both min-file-size and max-file-size to the old value (according to the log message).
[2012-01-16 19:23:30.995499] E [io-cache.c:1673:reconfigure] 0-io-cache: minimum size (23068672) of a file that can be cached is greater than maximum size (23068672). Hence Defaulting to old value

But gluster volume info still shows the wrong input value given by the user only.
