Well, sort of. I think a big portion about it for me was figuring out the TaskAttribute and ACA handling. Basically, many of these assumptions are (well?!) communicated to the block layer by the SCSI protocol (not even iSCSI, that is a thin layer) - but configuring it on the target side was always poorly understood.

We run "Ordered" - without queueing - so we essentially are trading off some /more/ performance for reliability in this situation. The block layer tends to handle it well in most OS.. I'll be game to test what softraid crypto would do to it (luks actually handles it reasonably!)

In terms of encrypted transport - the value is mostly in HMAC layer. That might die oddly if the ISPs decide to mess around with these packets because they look too cute - but for encrypted FS, it shouldn't be accidental, only malicious. (Accidentally, I've seen ISPs get upset over MPEG streams over netcat!)
