Journal TheRaven64's Journal: A Leopard ate my ~
There is no way I could feel more disdain for Apple's QA department than I do right now. It seems that, in spite of the fact Leopard was in development for over two years, no one bothered to test what happened when you updated an account using FileVault from Tiger. My experience was:
- The installer worked fine.
- I logged in, and used the OS for a day.
- The kernel paniced.
- On rebooting, my home directory was inaccessible, and Disk Utility was unable to repair the disk image.
Oh well, I thought. It's an occupational hazard when using an encrypted disk image for your home directory; if you don't get a clean shutdown then you can lose data. So, mindful of this, I restored from a recent backup and rebooted. Sure enough, there I was logged in again. Then, a few weeks later, I upgraded to 10.5.1, shut down cleanly, rebooted, and... couldn't log in. Apparently the disk image was corrupted. Worse, it turns out this is a known fault: Leopard always leaves FileVault home directories created with Tiger in an unmountable state when you log out.
I'm going to say that again:
Leopard always leaves FileVault home directories created with Tiger in an unmountable state when you log out.
What kind of monumentally incompetent design is this? I have no idea. Anyway, enough of the ranting. I'm sure what people really want to know is 'what do I do when my shiny new OS has just eaten 30GB of personal data.' Step one is to swear at Apple. A lot. Step two is to realise that this 'corrupt' disk image, with a 'bad superblock' actually mounts fine in Tiger still. Fortunately, I haven't 'up'graded my Powerbook to Leopard. I booted the MBP in target mode, mounted it on the PowerBook, mounted the disk image and copied all of the files out.
I now had
This lead to the question of how to tell OS X that I was no longer using FileVault. Apparently this isn't documented anywhere I could find via Google and so I had to spend a long time hunting through the filesystem. Thanks again Apple.
It turns out that the relevant file is
Once upon a time, Apple was known for attention to detail and thorough testing. I suppose their current activities are good news for Étoilé, but I'd rather we competed by raising our standards than by Apple lowering theirs.
