I hate to ask, but did you tick the checkbox for "erase disk"? The block copy cannot occur without this selected.
99% sure it was set in the auto run. I'll double check.
Odd, it doesn't show my Recovery HD or other partitions either.
Erase disk IS checked.
More info:
I can not unmount any internal drive while net booted.
I can unmount from recovery HD.
Diskless is checked on Netboot server.
NBI is a clean install of 10.7.4 auto login as root. No other software installed.
When I force unmount from Terminal all hell breaks loose.
Seems like something is in use during the net boot...
Is your NetBoot image diskless?
FIXED!!!!
STUPID SACL!!!!
I turned that off and everything is great. It wasn't able to create the shadow file on the AFP share.
Thanks for all the help.
Matt4836 - what did you do to turn off SACL?
