Failed to mount sparse image... what does this mean?
 
I have a sparse image that resides on a pair of mirrored external 1TB LaCie drives. I manually run SD every night; the last action I take before leaving the computer.

I noticed this morning that last night (and now again today) SD is failing. It repairs permissions on the internal HD (the one being backed up), and fails when it tries to mount the sparse image.

I can double-click on the sparse image and mount it manually. (I unmount the sparse image before attempting to run SD again.)

This is very odd. Here's the log

Try restarting your Mac, rithban. Typically, that'll correct the problem, which is due to a low-level issue in OSX's IOKit.

OK... that did the trick. Seems like every OS has a niggly in a library somewhere.

Hey Apple! What's the big deal, guys? Can't you write a measly million lines of code without messing up? Geez Looeez! :D :D :D

dnanian 08-20-2007 12:34 PM

Yeah, this is a weird one that only affects some users...

rithban 08-20-2007 12:43 PM

Doh!

I have a note here from some months ago about rebooting when encountering IOKit oddities.

I have so few problems with OS X (and Linux) that rebooting never comes to mind. (But when doing development work rebooting Windows is just part of a day's work.) Funny how the human brain works.

Thanks for the reminder! *blush*
