Pierre-Luc Dion commented on CLOUDSTACK-6166:
---------------------------------------------
There is a not about the async flag, at the end of this page:
http://cloudstack-installation.readthedocs.org/en/latest/storage_setup.html
sync is usually not performant which probably explain the reason for this
configuration.
> 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...
