Just to help Tony out, here were the two postings he attempted to
send from his non-subscribed address.

Sftp and schedule are pretty much the same under the covers- all you need
on the server is sshd. You can set up an occur on the server that prohibits
shell access I don't recall the details offhand.

ZFSday quote...

Y4K? ? George Wilson

For over 30 years, hard drives have designated the smallest storage
location as 512 bytes. In January 2011, all major hard drive manufactures
began shipping their hard drive platforms using a new standard called
Advanced Format. To aid in the transition, these new hard drives provide a
512 byte emulation mode that allows the drives to advertise themselves as a
512 byte addressable devices. This can severely impact write performance
resulting in the need for read-modify-write operations for any misaligned
or partial writes that are issued.

The problem is not limited to just physical hardware. Other storage
platforms may also provide LUNs (logical unit number) that presents
themselves as a 512 byte addressable devices when, in fact, they use a 4K
sector size internally. Although ZFS has built-in support for 4K sectors,
it has no automatic way of dealing with the lies that the storage devices
tell. This talk will focus on the methods that have been developed to work
around the lies that hard drive storage platforms tell and will discuss the
challenges and drawbacks that come with using 4K sectors.
