Jeremy Schaffer commented on CLOUDSTACK-586: -------------------------------------------- This is due to the new syntax of the /etc/exports in Ubuntu. Since it assumes the default of no_subtree_check the line should read: /export *(rw,async,no_root_squash,no_subtree_check) > exportfs -a gives 'no_subtree_check warning' when following the Installation > guide > ---------------------------------------------------------------------------------- > > Key: CLOUDSTACK-586 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-586 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Doc > Affects Versions: 4.0.0 > Environment: Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-29-generic x86_64) > Reporter: Max Thoursie > Priority: Minor > > The installation guide says, under 4.5.5.1 and 4.5.5.2 > 2.
