System Image Utility: NetInstall creation failed

A debug log will give you much more complete information but, it appears that it's failing trying to move the asr image (System.dmg) into the shell image (NetInstall.dmg).

As I recall, on Snow Leopard, the OS is installed to the shell image. So, the combination of the OS + System.dmg has gotten larger than the space that was determined necessary for the creation of the shell disk image.

In other words, if I interpreted your description correctly, System.dmg is 49.1GB. If you mount NetInstall.dmg, it will have less than 49.1GB available on it.

I've seen this happen when the filesystem compression (somehow) gets disabled, causing the installed system to be larger than expected.

I'm getting the same/similar building a 10.10 NetRestore image. How does one get compression to be nice and reliable?

Or is there something else I'm missing? I installed 10.10 and 10.10 server/tools the same day, so should be in sync, right? I'm using a procedure I've done successfully for a long time with Mavericks. Any suggestions, of course, are welcome.

If I'm reading your log correctly, your source image is in the vicinity of 55 GB in size. You've probably had this work with smaller sources. Suffice it to say this is a bug in System Image Utility.

The images have been in that size range a long time, and they have always taken a while to create, but work well for our classroom.

Ironically I did web searches for issues with 10.10's SIU, found none, then too confidently upgraded. I will hope for a fix with 10.10.1...unless you know a workaround of course!

I don't believe it's a new problem... it's very possible Jeff ran into the same thing. To fix it without a patch from Apple would require hacking around the the bowels of System Image Utility.app.

Same here: Server 4 on a Mac mini (Late 2012) with FusionDrive (1.11TB) running 10.10.1. Trying to take Image (of a McBookPro)

The key is (the obviously wrong) message: mv: /tmp/mnt.uy0ENoi0/Packages/System.dmg:) No space left on device

But I have 1.08 TB space left on the Volume .... ohhhh apple - not again!

should probably add: I can take an image of a MacBookPro with just 9 GB of space occupied ...

I actually have the exact same issue. I tried to capture an image of a Macbook Air onto my server and no matter what i did i got hte same result you did.

I finally got it to work by re-creating the image on a macbook pro (2010 model via firewire/target mode/without an SSD) and it worked. I found that capturing an image of a mac with an SSD always seemed to be problematic for SIU, but once i tired to capture the same image from an older macbook pro, it always worked.

I really do hope they fix this issue soon, its been on-going far too long.
