HowTo: Exporting a new dCache NFS directory

Working with GIT + Puppet

• In order to change exports for the dCache NFS service you need to changes in Puppet.

• Follow HowTo: dCache Management - GIT + Puppet to see how to download and propagate changes in Puppet.

Add a new export

• Add a new export by editing the Puppet class dcache::configuration::door::nfsv41
• Modify the corresponding Puppet Resource common::nfs::exports or create a new Resource of this if needed. In example:

diff --git a/manifests/configuration/door/nfsv41.pp b/manifests/configuration/door/nfsv41.pp
index 373ae5d..ddbbbe1 100644
--- a/manifests/configuration/door/nfsv41.pp
+++ b/manifests/configuration/door/nfsv41.pp

                       }

                               v4_export_root => '/pnfs/pic.es',

• Commit & push changes

Run puppet in the NFS Doors

• In example:

puppet agent --test --server puppet03.pic.es --logdest /var/log/puppet/puppet.log --environment=production

Reload dCache configuration

• Access to the dCache Admin Console

ssh -2 -x -o StrictHostKeyChecking=no -l admin -c blowfish -p 22224 dccore.pic.es

• Once logged in the admin console:

1. Move to a NFS door with the command cd. In example, for dcdoor05.pic.es:

   cd NFS-dcdoor05

2. Reload the configuration by running:

   exports reload

3. Repeat 1. and 2. for all doors where changes need to be applied.
