I forwarded your questions to the guy who implemented journaling in
HFS Plus and he just got back to me with a response...
<clip> Thanks, Quinn, for taking the time to forward this to your contact on the HFS team, and for their comprehensive reply. Together with an excellent technical article in the Macintosh Developer's Journal, I think I've got all the information I was looking for. Except for one last nagging question. Looking at the boot logs, I'm pretty sure I know the answer but I'm still looking for a definitive statement. When you boot OS X in single user mode, the root filesystem is mounted read-only. When a journalled HFS volume is mounted read-only, is the journal still replayed? From my casual testing, it appears that it is -- despite the fact that this sort of goes against the concept of "read-only". If anyone has any information on the behavior of an HFS journalled filesystem when mounted read-only, I'm dying to find out. ______________________________________________________ James Bucanek <mailto:privatereply@gloaming.com> _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
