# This script is designed to rebuild an Edge server from a checkpoint off the master. 
# You have to first copy the checkpoint from the master to the edge server before running this script.
# Then you run this script on the Edge server with the instance number and full path and filename
# of the master checkpoint as parameters.
#
# Run example:
#  ./recover.sh 1 /depotdata/p4_1.ckp.9188.gz
