Hi,
I have a FreeBSD 7 running on harddisk /dev/ad6.
I have a second harddisk which is currently not empty at /dev/ad4. On /dev/ad4 is a former FreeBSD 8 installation. This /dev/ad4 is part of the mirrored geom mirror/gm0.
I want to erase /dev/ad4 and combine /dev/ad6 and /dev/ad4 to one mirrored geom.
When I run [cmd=]gmirror status[/cmd] I can see "COMPLETE" for /dev/ad4 which is correct. But what happens if I add /dev/ad6 to /dev/ad4? It will "sync" the harddisks, but what does it mean? Will it erase the data on /dev/ad6 as /dev/ad4 is the "master" (if this term exists in a RAID) or will it copy /dev/ad6 to /dev/ad4?
The problem is that the system is currently running (not in use) and I dont have physical access at the moment, so I can not do the "normal" way booting from a DVD.
What would you suggest to do? I mustn't lose the data on /dev/ad6 (even backup exists for the worst case).
Can I make sure that /dev/ad6 is copied on /dev/ad4? In the meantime I would activate gmirror on boot and edit my /etc/fstab.
Thanks for recommendations.
