Hi,
   i want to config namenode HA with hadoop 2.0, but i don't have any NAS
device. instead i have SAN disk array.
   my question is:  Do you have any experience using REDHAT GFS  as "share
storage" between two namenode for HA?
  is it works? As we know from hadoop.apache.org that "NAS" stoarge is
recommended.
Best R.
