[jira] [Created] (CLOUDSTACK-6166) Should we be recommending ASYNC NFS in documentation?

John Kinsella created CLOUDSTACK-6166:
-----------------------------------------

             Summary: Should we be recommending ASYNC NFS in documentation?
                 Key: CLOUDSTACK-6166
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6166
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Doc
            Reporter: John Kinsella
            Priority: Minor


Looking at current and past installation, we recommend users export secondary storage with async NFS:

/export  *(rw,async,no_root_squash,no_subtree_check)

Generally async mode is considered risky from a data reliability point of view (eg http://serverfault.com/questions/328931/how-dangerous-is-nfs-async-when-raid-bbu-and-ups-are-present ).

While advanced users will see this and ignore it, we probably shouldn't be guiding new ACS users towards async NFS...
