I'm currently trying to decide between = LVM2 (is it in 2.4 already?), MD, and a "manual" nightly rsync onto the seco= nd disk. I'd like a few pointers (RTFwhatever welcome) to the following question= s: How about RAIDing the root partition? If one drive fails will the other= be able to boot via LILO? How about GRUB? Which do you prefer? How about (/var)/tmp? I (suppose I'll) need it on both disks, does it m= ake sense to mirror it as well? Can I mirror the whole disk? Or do I need to mirror each partition seperately? Does MD or LVM2 do hot sync, i.e. if one drive fails will I be able to = stick in a replacement, and stop worrying? Or do I need to repartition the ne= w disk exactly as the old one, before being able to sync? How does LVM2/MD deal with failing harddisks, which is why I do the mir= ror at all? I've heard about MD not detecting read errors because the "othe= r" disk was reading fine, and crashing completely when one disk was finall= y replaced because the data on the other disk was also corrupt. Is that s= till the current case? The goal is to have as "stress free" a system as possible - i.e. with a= s little manual configuration, and in event of emergencies, as little wor= k to do, as possible.
