Evidently fixed in a later release...
I think there's some confusion here. The download cache is always stored
in the *current* BE before the new BE is created. While you will see the
client "go through" the download process -- it shouldn't actually
download files unless they're missing or corrupt.
Well, that's what I always thought, and of course you are correct.
FWIW, it took about 4-1/2 minutes just to delete the BE and around
10 minutes just to create the plan and iterate over the first 78 pkgs.
You really can't tell the difference between the rate at which the pkg
counter goes up when downloading for real or iterating over the
cache, which wasn't the case with iscsitgt. Because it was relatively
slow and snoop did show some traffic to opensolaris.org, it was only
too easy to come to the wrong conclusion.

Now, the progress indicator will appear to re-download the files it had

usually notice that this portion of the "download" happens much faster than
if the bits are actually coming off the network.
Ah, if only :-). It takes around 45 minutes before the iscsi target disks
go offline during the install phase, which is abysmally slow compared
to iscsitgt, which took only 15 minutes or so to install from the cache.
There were some pointers to specifics in the evil tuning guide on
zfs-discuss recently and maybe there have been some COMSTAR
performance fixes since b124, so I'll try moving the initiator over
to a machine running b132 and see if it can get any further.
Sorry about the noise.
Thanks for taking the time to reply -- Frank
