PREREQUISITE

• cluiclient downloadable in HP Replication Solution Manager Software (http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3807693&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3DswItem%253Dco_51723_1&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken)
• openjdk-jre (for cluiclient)

INSTALL :

• Copy this directory in ExtStorage Providers search path (/srv/ganeti/extstorage, /usr/local/lib/ganeti/extstorage, /usr/lib/ganeti/extstorage, /usr/share/ganeti/extstorage)

• Copy and complete eva.conf in /etc/ganeti/extstorage/

• Copy cluiclient wherever you want and adapt config file

• Patch function NewUUID() in /usr/share/ganeti/ganeti/utils/io.py to match this one :

   def NewUUID():
     """Returns a random UUID.
  
     @note: This is a Linux-specific method as it uses the /proc filesystem.
     @rtype: str
  
     """
     return ReadFile(constants.RANDOM_UUID_FILE, size=18).rstrip("\n")
  

• (ganeti < 2.12) Patch function GenerateDiskTemplate() in lib/cmdlib/instance_storage.py :

     # Only for the Ext template add disk_info to params
     if template_name == constants.DT_EXT:
       params[constants.IDISK_PROVIDER] = disk[constants.IDISK_PROVIDER]
   +   params[constants.IDISK_NAME] = disk[constants.IDISK_NAME]
  

• restart ganeti

TODO

• Grow function : It seems that cluiclient does not want to resize a VD with thin provisionning disabled.
