Hi all!
I'm a "nervous nellie", I have not yet updated my 7.5 desktop to 7.6 because (1) it has an Nvidia card, and (2) I've heard of problems upgrading on top of software RAID (using RAID1 with 2 drives).
I need to upgrade it to stay secure, and I want to do a bare-metal backup first (so I can put it all back as it now is, in case it explodes in my face), so I'm trying to figure out the safest way to do that. Here are the choices as I see them, I'd appreciate comments/thoughts:
- boot from live DVD and manually reassemble the RAID array (how
would I do that?) 2. degrade the array (with appropriate commands) so that it is running on just one drive, then boot a live DVD and use dd to back up that drive. 3. Other choices you can suggest?
then after successfully getting a bare-metal backup, reboot it with the full RAID array and run the update.
Thanks in advance!
