Unable to erase "Macintosh HD" from netboot...

[#1]

I have a strange problem with netboot, in that it will not erase disks. I
get this error message :-

The netboot image was created from a external USB drive I have. This USB
works fine & I've been doing the same process for years, its just now it
will not allow me to erase disks.

I've been scratching my head for a while on this & wondered if anyone else
has come across this before?

There is nothing on this USB drive other than a minimal 10.6.6 install i.e
with out the printer drivers & fonts, with nothing else installed. The
netboot box is a MAC Mini server running 10.6.6.

Peace

Is your Netboot image configured as "Diskless" in Server Manager? A

Hi William

Diskless images was not enabled. An ID10T error? ;)

We also run diskless netboot and run into this problem. We've created a "nuke and pave" script that techs can click in the dock that basically uses diskutil to flatten the drive. It appears to be a bug in Disk Utility from what we can see.

Was a bit of a strange one, as it put our image time up from 15 minutes to
45'ish as Casper had to manually erase all files & folders before it would
drop our image down.

45 minutes per machine is not bad anyway, but when you have been used to 15
minutes it was a bit of an head scratcher.

I've had a same kind of issue and got fixed by giving AFP service "Allow all users and groups" in Server Admin "Access" settings.

I ran into this as well. Assuming you have your NetBoot image set as diskless and that NetBootClients is shared via AFP. The issue was that I had SACL's enabled for AFP (as @Kumarasinghe indicates disabling). Rather than disabling the SACL I added all netboot users (these are system accounts that get created automatically) to the SACL list for AFP. To do this you first have to set Server Admin to "Show system accounts in users & groups browser" in Server Admin preferences. Then click on your server in Server Admin, go to the Access pane, select AFP, click the plus button to add users, search for netboot (by default there are 50 starting with netboot100-149) and drag them to the allow list. Then save.
