To Openfiler From Another Machine (a Freenas server)

1. In Freenas run the RSYNC service
2. Goto Services > RSYNC > Server > Modules and create a module from the right directory
3. Use ssh to log into your Openfiler box
4. To query which modules are available (notice the double colon):
   # rsync freenas.yourdomain.com::
   DATA            MY DATA
5. To rsync from the module (notice the double colon again)
   # rsync -avu freenas.yourdomain.com::DATA/* /mnt/vg_data01/data01/data/
6. This one worked for me too(create the user first in Freenas)
   # rsync -avu This e-mail address is being protected from spambots. You need JavaScript enabled to view it :/mnt/DATA/* /mnt/vg_data01/data01/data

To a Freenas Server From Openfiler

1. First create a module on Openfiler:
   # vi /etc/rsync.conf
   
   # PLEASE DO NOT MODIFY THIS CONFIGURATION FILE!
   #       This configuration file was autogenerated
   #       by Openfiler. Any manual changes will be overwritten
   #       Generated at: Sat Jun 6 0:32:09 CEST 2009
   
   port = 873
   motd file = /opt/openfiler/etc/rsync.motd
   address = 192.168.0.10
   
   # End of Openfiler configuration
   [data]
           comment = data
           path = /mnt/vg_data01/data01/data
           read only = no
           list = yes
           hosts allow = 192.168.0.0/24
           secrets file = /etc/rsyncd.secrets
           uid = nobody
           gid = nobody
   
   And then reload rsync:
   # service rsync reload
2. Now you can schedule a RSYNC job in Freenas:
   Services > RSYNC > Client and create the job using the module name.
3. Check the Freenas logs by going to:
   Diagnostics > Logs > RSYNC > Client
   
   So remember that this is for getting data TO freenas, not From Freenas to Openfiler. I thought it was the other way around and I lost 50GB of data before I was able to stop the process (by shutting down Freenas). Damn.
