Just finished installing 2.1.5R (went very smoothly, thanks Team FreeBSD!) and thought I'd try disk mirroring using ccd. I want to mirror the contents of my entire file system so that I can reboot from one of the disk if the other fails. I have read the documentation; ccd home page and man pages and am still unclear on exactly what I need to do. I have two idential SCSI drives, sd0 & sd1. Right now the OS is installed on sd0 and I have done nothing to sd1. Do I; 1. recompile a new kernel with 'pseudo-device ccd 4' ? 2. use dd to copy the contents of sd0 to sd1? (do I need to use disklabel,partition first?) 3. create the /etc/ccd.conf file with CCDF_MIRROR flag? 4. now run ccdconfig, creating device ccd0? 5. is ccd0 now my device with the original filesystem installed, except now I am mirrored? 6. by default, I think the system will boot from sd0. If sd0 fails, how do I get the system to boot from sd1, will it automatically check for a valid system there? 7. how do I test if ccd is working? Thanks in advance for your help. I will compile any responses I get for possible inclusion in the handbook. Neil Jensen Habanero Studios Ltd Vancouver, Canada
