Ok, so the answer so far is to use Lenny, as it's installer will guide
me through the process of setting up RAID1.
Mirror both disks because then you're covered for disk failure.
Make sure the bios know to boot from the other disk if the first fails.
Make sure grub is the same on both disks so that everything books up.
mdadm is a tool for managing the RAID configuration, but I can't find a
decent functional overview that clearly explains the scope.
QUESTIONS...
What tools do I need to know about?
What reporting do I get and how do I get it? (email, logs, etc)
What tools do I need to use to monitor the disks to make sure they're
not failing?
(Can you tell I'm a guy who's never had a disk fail before? So I've
never worried about monitoring them.)
How do I test the array once I've built it? Being SATA is hot start, I
assume I can just pull the data cable off and things should keep
trucking? Can I assume I'll get an alert some how?
If I write data to the disk while one disk is missing then it will need
to resync once the disk comes back. How long does this normally take?
Is there a delay?
How do I put a new disk in if one fails? Can I just wack a blank disk
in and the tools will sort out the rest?
What happens if disk 0 fails, data is written to disk 1, then disk 0
comes back, then disk 1 fails, data is written to disk 0, then disk 1
comes back. Will it sync everything up correctly even if some recovery
hadn't been finished between failures?
What other gotya's do I need to know about?
Cheers Don
