Goal

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance

This document explains how to set up the 'ftp' service so that uploads can resume from where they have been stopped. On the ZFS appliance, the 'ftp' service is based on 'proftp' with "AllowStoreRestart" not defined. This was mainly chosen by design, for security considerations.   


See http://www.proftpd.org/localsite/Userguide/linked/config_ref_AllowStoreRestart.html :

"Care should be taken to disallow anonymous ftp "incoming" transfers to be restarted, as this will allow clients to corrupt or increase the size of previously stored files (even if not their own)."

Under the 2011.1.* Appliance Firmware Releases, here is what "curl" gives when "AllowAutoRestart" is not defined (or set to "off").
The nas head has been rebooted and we try to resume the interrupted 'ftp' upload.
