Greetings,
First, apologies if this is the wrong forum. Please direct me to the right place if it's not.
I'm trying to find some definitive word about using fsck on a Journaled HFS+ file system. I'm technical editor for a book on OS X and I'd like to get to the bottom of this.
I've heard that you should never run 'fsck -fy' on a Journaled file system. I've heard that you should always run 'fsck -fy'. I've heard that Journaling is implemented in the file system, so if you boot up in single user mode and run 'fsck -fy' that the journaling system will later "undo" any fixes. I've heard that in single user mode that the journaling system has already done any required repair before you get to the single user prompt.
In other words, I'm confused.
What I'm trying to find out is: When do journaling fixes get applied. What exactly does 'fsck -f' do? Under what circumstances can the two conflict? And what's the generally accepted practice for maintaining volume integrity when using Journaled HFS+?
Yea, I know, it's a lot of questions. But any insight or advice would be greatly appreciated.
Cheers,
James
