Remove node from gfarm 1.3

This instruction apply to Gfarm 1.3.1 using Postgresql backend metadata storage only

1. Remove the node from your cluster. Ex: For NPACI Rocks 4.2

insert-ethers --remove compute-0-7

2. Use psql to access gfarm database. Make sure to change the port number to the correct port. Use 'ps auxw | grep postmaster' to find the port number

psql -p 10602 gfarm farm

3. From psql prompt, input

DELETE FROM filesectioncopy WHERE hostname='compute-0-7.local';

4.Exit from psql. Now the node has been removed permanently from database. Remove it from gfarm now.

gfhost -d compute-0-7.local

That should be all.
