I just go about my business and try not to create too much trouble for myself. To be honest and truthful I have to say that this journaling stuff entirely snuck up on me. I confess... I wasn't paying attention (to the world of FreeBSD innovations) and thus, when I moved myself recently to 9.x (from 8.3) I did so without even having been aware that the new filesystems that I was creating during my clean/fresh install of 9.1 had journaling turned on by default. (As the saying goes, I didn't get the memo.) Not that I mind, really. It sounds like a great concept and a great feature and I was happy to have it right up until the moment that "dump -L" told me to go pound sand. :-( So, um, I was reading about this last night, but I was sleepy and my eyes glazed over... Please remind me, what is the exact procedire for turning off the journaling? I boot to single user mode (from a live cd?) and then what? Is it tunefs with some special option? >> If I use all of the following rsync options... -a,-H,-A, -X, and -S .... >> when trying to make my backups, and if I do whatever additional fiddling >> is necessary to insure that I separately copy over the MBR and boot loader >> also to my backup drive, then is there any reason that, in the event of >> a sudden meteor shower that takes out my primary disk drive while leaving >> my backup drive intact, I can't just unplug my old primary drive, plug in >> my (rsync-created) backup drive, reboot and be back in the sadddle again, >> almost immediately, and with -zero- problems? > >It works.

Thanks Warren. >Use the latest net/rsync port, and enable the FLAGS option. I use these >options, copying each filesystem individually: > >-axHAXS --delete --fileflags --force-change Hummm... I guess that I have some non-current rsync installed. In the man page I have there is no mention of any "--force-change" option. What does it do? >Yes, the partitions and bootcode must be set up beforehand. After that, >it works. Good to know. Thanks again Warren. >Like any disk redundancy scheme, test it before an emergency. Naw.
