problem (again) booting from underlying volume after Sandbox updated
Well, it happened again! (See this post for original issue).
Once again, my Mac Pro won't boot from the main hard drive but WILL boot from the Sandbox created from that drive. Same symptom: I hear the chimes, the gray screen appears, the gear spins for about 2 seconds, and the machine shuts down. Here's what I noticed....after restoring from a month old SD! backup and reapplying changes to the main drive I made in the last month, I again created a Sandbox. I booted off of the Sandbox. A few days later I applied the Combo Updater to update the Sandbox from 10.5.2 to 10.5.4 and then rebooted off of the Sandbox and all seemed good. Then, a few days after that I wanted to boot off of the underlying main drive, and wham, the Mac Pro shut down, just as it did weeks earlier! So, it seems there is some evil interaction going on. Fortunately, I have a relatively recent SD! clone that I made right after getting my HD back to speed (a good caution, I guess!). I'm going to conduct a test....after creating a new Sandbox, I will (a) make sure I can boot both from the Sandbox and the main drive, (b) apply the 10.5.4 update to the Sandbox, and see if I can boot from the main drive. I will not use the machine for anything else as I conduct this test, so we can be (relatively) certain that it's the step of applying the OS update that is the culprit (if the symptom occurs again!). I'll report back shortly, I hope. |

You should send me a "system.log" from the drive that shuts down -- send it to the support address. It might indicate *why* it's shutting down.

A (possibly) dumb question....how do I send you a system.log from a drive I can't boot off of? In the past, the way I've gotten logs is via Console, but not from a different drive. Is there a place I can find the system.log of the offending drive while booted from a different drive (obviously, I can't boot from a drive that won't boot!).

Well, that test crapped out! Right after applying the 10.5.4 combo update, I was able to boot up both off of the Sandbox and the main drive. Darn! So much for that theory!
I WAS able to locate the system.log file. I think what I need to do at this point is to work off of the Sandbox, as I prefer to, and periodically try to boot off of the main drive. The next time it won't boot, I'll send you the system.log file. Now, what I've been doing to recover from this mess is that when I couldn't boot off of the main drive but COULD off of the Sandbox, I've copied my Desktop and Documents folder to some free space somewhere, cloned back using SD! from a working, booting backup, and copying back the desktop and documents. That's really tedious, because it takes about 45 minutes each way to copy the docs and desktop (mostly the docs). Is there a better way? Thanks, as always, for your help. |

If you're cloning back, I don't quite see why you're copying off Desktop/Documents, because they never 'move' -- they're on the original drive anyway. And you should always be doing a regular backup of the base drive.
As far as getting the system.log from the base drive when you're on the sandbox, you'd use Finder's "Go To Folder" command to open /Volumes/the-base-drive-name/private/var/log system.log is in there.

I have a complete SD! clone that's, say, a week old. In the last week, I've altered documents. Since the Sandbox boots, and the main drive doesn't, I want to restore my system on the main drive back to health. If I just clone back my week-old SD! backup, I lose any document file changes in the last week. So, what I've been doing is:
Am I missing something obvious? |
