NetBootSP0 folder unsharing itself?

Question

NetBootSP0 folder unsharing itself?

The server system is a Mac Mini running OS X Mountain Lion Server(10.8.5). It was originally running 10.6.x. It has 8GB of RAM, and dual 1TB hard drives in a RAID-1 configuration. I know that the Mac I'm trying to boot can boot from the particular Netboot image, because it's done so in the past. The network is all 1Gbps over ethernet, and there are no known network issues.

I use Netboot, and have for many years. I'm trying to use Netboot, but the NetBootSP0 keeps unsharing itself. It's bizarre.

I'll make sure the NetBootSP0 folder is shared, then try to netboot a Mac, and it will fail to do so. Then I'll open /Applications/Server.app, check the File Sharing pane, and sure enough, the NetBootSP0 folder has become unshared.

I just want to be able to continue netbooting as I've been doing for many years.

Any ideas?

Mac mini, 10.8.5

I had this happening on each & every version of Mac OS from Yosemite to Sierra

On upgrade, on brand new clean install

It is completely bonkers!

I have never ever managed to "fix" it

Sometimes it stays for 24 hours, sometimes it happens after 10 minutes!

No sense or logic

Check the server logs/syslog for anything that might indicate why the service is being stopped.

Maybe you have some sort of permissions issue on the folder. You could set aside any images, deconfigure NetBoot, delete the /Library/NetBoot folder, and reconfigure NetBoot so it recreates the folder structure. Then copy your images back into the new NetBootSP0 folder.

Thanks for the suggestion. I disabled Netboot, renamed the NetBoot folder to NetBtOld, and flipped the switch to enable Netboot. It momentarily flipped on, then flipped off, but it did generate the folder structure.

Then in the Terminal, I entered

rsync -avuE /Library/NetBtOld/NetBootSP0 /Library/NetBoot/NetBootSP0/

then enabled Netboot, shared the folder, and everything seems to be working as well as it used to.

Thanks again.
